The most common type of vacuum pumps and measuring gauges based on available literature are studied with emphasis on how new research and development will enable the new generation of vacuum technology specially in designing, its operational procedure and applications. The technologies were developed to meet the operational goal which include vacuum chamber structures, compatible materials, specialized vacuum pump and gauges. There are many areas where different vacuum condition is required for conducting experiments therefore modeling of pumping system is on demand. The basic understanding of how and when the particular pumping and measurement system can be applied most effectively and economically is essential. The poor choice of pumping and measurement system will interfere the scientific objectives and may leads to substantial maintenance demands and an unpleasant working environment. The development and fundamental investigation of innovative vacuum techniques for creation and measurement of vacuum used for various applications necessary for the research work to be done in future are presented.

Abstract Vacuum fluctuation was measured using three different vacuum control methods. Firstly, the use was made of a control valve delivered by the manufacturer; then, an additionally installed frequency converter was used. Lastly, a frequency converter fitted with the stabilisation device prototype was used. First, control sensitivity according to ISO was measured in all the three alternatives. Then, vacuum fluctuation during milking was measured. To conduct the measurements under objectively identified conditions, another measurement was conducted with air feed during milking being replaced with a precisely defined variable flow rate. The conducted measurement confirmed the fact that when the frequency converter is used, vacuum fluctuation in stabilised condition is at the same level as when the control valve is used. If there are sudden changes in flow rate and the frequency converter is used, vacuum fluctuation increases. The proposed stabilisation device prototype can reduce the fluctuation in small milking plant but it is not suitable in large milking parlours.

An especially important direction in metrological science is ensuring the accuracy of vacuum measurements, which is crucial for industry. In Russia, predominantly foreign vacuum gauges with a vacuum measurement range PNPI – PVPI 0.1–1000 Pa are used as reference vacuum gauges for verification and calibration of vacuum gauges. On the basis of the analysis of the characteristics of reference vacuum gauges used in Russia based on various methods for measuring gas pressure, it can be argued that the most accurate and common measurement method among reference vacuum gauges is the strain method. However, the strain method has a number of limitations associated with the need to introduce the following corrections: correction for the residual pressure in the comparative chamber, correction for the influence of temperature effects during temperature control of the primary measuring transducer. The purpose of this work was to study the compliance of the metrological characteristics of a vacuum gauge based on a new strain-frequency method for measuring the absolute gas pressure with the requirements for reference vacuum gauges given in state verification schemes in the field of vacuum measurements.The main research methods were the study of the metrological characteristics of the strain-frequency vacuum gauge, taking into account the correction for the residual pressure in the comparative chamber; corrections for the influence of temperature effects during temperature control of the primary measuring transducer, as well as for the compliance of the method with the requirements of state verification schemes in the field of vacuum measurements. An assessment of the accuracy indicators of the strain-frequency method for measuring the absolute gas pressure based on the analysis of the measurement equation, taking into account the assessment of the components of the uncertainty sources, is given. The obtained results have shown the possibility of using the strain-frequency method of pressure measurement, with the exception of the correction for the residual pressure in the comparative chamber, corrections for the influence of temperature effects during temperature control of the primary measuring transducer in reference vacuum gauges that meet the requirements of state verification schemes in the field of vacuum measurements.As a result of the study, it was found that the expanded uncertainty of the result of measuring pressure with a vacuum gauge based on the new strain-frequency method does not exceed 2 %. This makes it possible to use this method in reference vacuum gauges.The practical significance of the developed scientific and methodological principles, and technological solutions for calculating and manufacturing the primary measuring transducer of a vacuum gauge based on a new method for measuring low absolute pressure lies in the possibility to manufacture the primary measuring transducer at Russian enterprises using domestic technologies of microsystem technology.

Composite materials have traditionally been used in high-end aerospace parts and low-end consumer parts. The reason for this separation in markets is the wide gap in technology between pre-preg materials processed in an autoclave and chop strand fiberglass blown into an open mold. Liquid composite molding has emerged as a bridge between inexpensive tooling and large, technical parts. Processes such as vacuum infusion have made it possible to utilize complex layups of reinforcement materials in an open mold style set-up, creating optimal conditions for composites to penetrate many new markets with rapid innovation. Flow simulation for liquid composite molding is often performed to assist in process optimization, and requires the permeability of the reinforcement to be characterized. For infusion under a flexible membrane, such as vacuum infusion, or for simulation of a part with non-uniform thickness, one must test the permeability at various levels of compaction. This process is time consuming and often relies on interpolation or extrapolation around a few experimental permeability measurements. To accelerate the process of permeability characterization, a small number of methodologies have been previously presented in the literature, in which the permeability may be tested at multiple fiber volume contents in a single test. Some of the methods even measure the permeability over a continuous range of thicknesses, thus requiring no later interpolation of permeability values. A novel method is presented here for the rapid measurement of permeability over a continuous range of fiber volume content, in a single unidirectional vacuum infusion flow experiment. The thickness gradient across the vacuum bag, as well as the fluid pressure at several locations in the mold, were concurrently measured to calculate the fabric compressibility. An analytical flow model, which accounts for the compressibility, is then used by iterating the fitting constant in a permeability model until the predicted flow front progression matches empirical measurement. The method is demonstrated here for two reinforcement materials: 1) a fiberglass unbalanced weave and 2) a carbon bi-ax non-crimped fabric. The standard deviation of calculated permeabilities across the multiple infusion experiments for each material and flow orientation ranged from 12.8% to 29.7%. Validation of these results was performed by comparing the resulting permeability with multiple non-continuous permeability measurement methods.

Measurement of Raman shifts of a C60 thin film and the evaluation of their uncertainties were conducted. A C60 thin film with a thickness of about 1.2 μm was fabricated on a SiO2 substrate by vacuum deposition. Raman spectra of the C60 thin film were obtained using the laser beam power density of 5.7 103 mW mm-2. The measured Raman shifts were corrected according to the calibration curve that was prepared using sulfur and naphthalene as the reference samples. Standard uncertainties were calculated and combined in order to determine the combined uncertainty and the expanded uncertainty. It was found that the increase of measurement time and measurement points for the calibration curve leads to the higher reliability.

This work focuses on the interface circuitry design for MEMS resonator-based vacuum sensors. Two new measurement system topologies are proposed. The required specifications and the design of the comprising blocks for each topology are studied in detail. Next, the correct functionality and performance specifications of both architectures – designed in an IBM 0.13 μm CMOS technology – are presented through a combination of post-layout simulations and measurement results. Furthermore, the advantages and disadvantages of each design are examined in detail, followed by a comparison to similar commercial systems currently available on the market.Finally, setting the ultimate goal of building a low-power, monolithic, integrated MEMS-based temperature-compensated vacuum measurement system, areas with potential for future improvement, and expansion are discussed.

The diagnostic technique, polarization and depolarization current (PDC) is useful for insulation testing. It requires applying a DC step voltage to the test sample and measuring the current. To measure fast PDC phenomena a fast step is needed. One way of applying a fast high voltage step is to use power electronic switches. Series connection can be used to increase the voltage limit, but this result in unequal voltage sharing unless equipped with voltage balancing. In this work a high voltage vacuum reed switch is investigated as a simple and low-cost alternative to power electronic switches, handling up to 10 kV with a single device. The switch turn on and off behavior was studied. It was found that the initial turn-on is good, in the range of nanoseconds, but there is a problem with the vacuum recovering its insulating properties at low currents before the contacts fully close. The required output voltage level is therefore obtained only after a further settling time that increases with increased input voltage and is much longer than the initial breakdown, e.g. 20 µs for the case of 4.5 kV input voltage. Other limitations of the fast high voltage PDC were also studied. The output voltage was measured across the test sample without adding an intentional resistor in the circuit. There were large oscillations for 1 µs but these oscillations are damped due to inherent resistance of the connecting leads, series resistance of the capacitors and resistance of the reed switch. A comparison is made between the measured and the simulated results using MATLAB to see the effect of parasitic inductance. A damping resistor was added in the circuit and the output results were again compared. With the addition of the damping resistor, the number of oscillations were reduced and their time scale was limited to 0.1 µs . An analysis is made at the end which describes the limitation occurring in determining the high frequency component of PDC. The current during the step is many orders of magnitude higher than the polarization current even at 1 µs , so measurement of the current and protection of the apparatus is not trivial.

Thesis (MScEng (Mechanical and Mechatronic Engineering))--University of Stellenbosch, 2009.
This thesis describes the development of a vacuum arc thruster (VAT) to be used as a potential low mass (< 500 g), low power (< 5–10W) propulsion system for nanosatellites. The thruster uses a high voltage capacitive circuit to initiate and power the arc process with a 400 ns high current (150–800A) pulse. A one-dimensional steady state analyticalmodel describing the cathode region of the vacuum arc was developed. The model made use of mass and energy balances at the sheath region and cathode surface respectively to predict key quantities such as thrust, ion velocity, ion-to-arc current ratio and erosion rate. Predicted results were shown to be within the limits of reported literature (∼63 μN/A, 26.12 km/s, 0.077 and 110 μg/C respectively). A sensitivity analysis of the analytical model found that a high electric field in the cathode region impedes and decelerates ion flow, which is used for thrust. This was confirmed experimentally for thrust values at arc voltages greater than 2000 V. Both direct and indirect means of measuring thrust were achieved by using a deflecting cantilever beam and an ion collector system, respectively. The transient response of the cantilever beam to impulsive thrust was analytically modeled, whilst the ion current was found by measuring the current induced on a plate subject to ion bombardment. Knowledge of the ion current density distribution was successfully used to approximate the effective normal thrust vector. Direct and indirect thrust levels were roughly 140 and 82 μN/A of average arc current, respectively. Measured thrust was found to be higher than predicted thrust due to thrust contributions fromthe ablation of Teflon insulation. The discrepancy is also due to the uncertainty in quantifying free parameters in the analytical model such as the fraction of generated ions flowing away from the cathode region. The thrust-topower ratio, specific impulse and efficiency of the vacuum arc thruster at an average arc current of 200 A was measured to be 0.6 μN/W, 160 s and 0.05 %, respectively. A thruster performance analysis and specification showed that the VAT is capable of achieving specific orbital and slew manoeuvres within a constant 5–10 W average power. It was concluded that thruster performance could be improved by using a two-stage arc circuit consisting of a high voltage, low current, short pulse trigger and a low voltage, high current, long pulse driver.

Out-of-autoclave manufacturing processes for composite materials are increasing in importance for aerospace and automotive industries. Vacuum Infusion processes are leading the push to move out of the autoclave. An understanding of the various process parameters associated with resin infusion is necessary to produce quality product. Variance in compaction, resin, and vacuum pressures are studied, concentrating on developing a compaction pressure profile as it relates to fiber volume fraction. The purpose of this research is twofold: (1) to show and quantify the existence of a resin pressure gradient in compression testing using rigid tooling, and (2) to use measured test data to validate and improve resin flow simulation models. One-dimensional compression tests revealed a pressure gradient across the diameter of the compression tool. The pressure gradient follows trends consistent with Darcy's Law. Compression tests revealed fabric hysteresis during compaction as shown in previous studies. Fiber compaction pressure was found to not be directly equal to compressive forces of the Instron when resin is present in the system. The relationship between Instron, resin and compaction pressures is defined. The compression study was used to validate previously developed flow simulation models. Resin pressures are critical to developing an accurate two-dimensional radial flow simulation for low permeability fabrics. It is feasible to determine final fiber volume fraction at a given compaction pressure.

In this thesis we have proven that the resistance to accumulation of gases in vacuum tubes is not always negligible. The process of accumulation was described using the Fick's second law of diffusion. The diffusion coefficient was assumed constant and evaluated, depending on pressure, considering Knudsen diffusion, molecular diffusion, or a combination of them. Experimental system with tubes of different lengths and diameters was built and equipped with two high sensitivity pressure transducers to measure the dynamic pressure difference along the system during gas flow experiments. Two cases were considered. First, the governing partial differential equation was solved analytically assuming a constant flow of gas into the system. Experimentally, a low-flow mass flow controller provided the constant flow of gas into the system. In the second case, the governing partial differential equation was solved numerically assuming a time-dependent flow of gas given by the Barrer equation. (Abstract shortened by UMI.)
