The ablation of solid pellets injected into high temperature magnetically confined plasmas is characterized by rapid oscillations in the ablation rate, and the formation of field aligned filaments in the ablatant. High speed imaging of the ablation (> 250, 000 frames/second) during the 2003-2004 campaign revealed that these filament move away from the pellet primarily in the poloidal direction with a characteristic speeds of ~ 5km/s. Significant differences appeared in the filament drifts in RF heated H-mode plasmas compared to ohmic L-mode plasmas. Filaments in ohmic L-mode plasmas moved in both the electron and ion diamagnetic directions while filaments in H-mode move only in the electron diamagnetic direction. Furthermore, the motion of the filaments in L-mode plasmas appeared to be semi-random, with the direction changing randomly from shot to shot, but with a distinct preferred direction during each shot. The susceptibility of the filament's motion to variations in the background plasma conditions indicate that the drift is a result of interactions with the background plasma, and not a result of the internal dynamics of the ablation cloud. Furthermore, the chaotic, or semi-random, nature of the filament drift suggests that the drift could be due to ExB flows resulting from plasma turbulence. A stereoscopic imaging system was installed on Alcator C-Mod to make a detailed study of three dimensional evolution of the filaments. By examining a large number of pellet injections into ohmically heated L-mode plasmas, we were able to demonstrate that filaments do indeed move primarily along flux surfaces, and that the filament flow direction is correlated for sequential filaments. Additionally, a statistical examination of the trajectory data revealed that filaments have a wider distribution of speeds at lower values of the local safety factor, q. The measurements of the stereo-imaging system were compared with the implied turbulent ExB drifts determined by the gyrokinetic solver GYRO. Simulations conducted using profiles consistent with both pre-pellet and post-pellet conditions demonstrate that the filament drifts are more consistent with the turbulent conditions prevalent after the injection, indicating the filament drifts are most likely the result of turbulence generated by the modified plasma profiles from injection process itself.

Pełny tekst źródłaThe preferred method of fueling fusion device is the use of D and/or T pellets injected into the plasma. They are currently used, but the results cannot be extrapolated to future larger reactors where the design of the injection system and the construction of scenarios will be mainly based on simulations. It is therefore important to fill in the gaps in the existing models from the manufacture of pellets to the deposition of material in the plasma. Two lacks of knowledge appear: the modeling of the pellet transport in the injection pipe and the validation of the ablation process. This work aims to fill these gaps and consists of 3 parts.- Describe the physics of material deposition, then the state of the art of the main results and finally the description of the pellet injection systems planned for the next machines.- Model the transport of the pellet in the injection pipe. The effects taken into account in the model are the weakening of the ice during rebounds, the increase in its temperature and its erosion. The model gives in particular the slowing down and the loss of mass of the pellet during the journey, as well as the stored elastic energy linked to its integrity on leaving the tube.- Contribute to the validation of the HPI2 ablation code, by comparing its predictions to data measured in ablation clouds. The method used is a calculation of synthetic data sets from simulations and comparing them to measurements. This method made it possible to validate the assumptions and approximations of the ablation model

Pełny tekst źródłaAn impurity pellet injector has been projected, built and installed in the TCABR tokamak, at the Physics Institute of Physics of the University of São Paulo - USP. Basically, the injector is composed of a high pressure gas chamber, in which the gas flow (N2 or He) is controlled by a fast switch valve. An high voltage (7kA) and high electric current (6kA) power supply has been built to provide energy for the valve. When fired, the propellant gas move the pellet into the interior of the tokamak vessel. During this process, the gas is properly collected before reaching the tokamak vacuum chamber. For this work, cylindrical carbon pellets with 0,4mm to 0,9mm in diameter and 0,5mm to 1mm in length were chosen as to investigate how the hazardous effects of a major disruption could be mitigated. The pellet ablation process in TCABR was studied trough running simulations that take into account, in a simplified way, the cooling of the plasma by the propagating pellet. The model, when applied to the T-10 tokamak experimental data, for example, exhibited very encouraging results. For the TCABR tokamak, in most of the cases in which pellets were injected, the plasma was terminated because of the advent of a major disruption. By analyzing the plasma current decay rate in two time intervals - within the end of plasma discharges, with and without the injection of pellets, it was observed that the plasma current decays significantly slower when pellets are injected. Consequently the load on the tokamak\'s electromechanical systems is reduced. Fourier analysis has been carried out to investigate the MHD activity near the disruption time, caused by the pellet injection. It could be noticed a reduction on the magnetic island\'s velocity rotation, after the pellet-plasma interaction initiates. Also, for all discharges analyzed, the MHD activities increased in amplitude after the pellet-plasma interaction. Another interesting result refers to the fact that the hard X-ray emission was observed to decrease significantly within the end of discharges in which pellets were injected

Pełny tekst źródłaIn magnetic or inertial fusion reactors, hydrogen, its isotopes, and lithium are used as fusion fueling materials. Lithium is considered a fusion fuel and not an impurity in fusion reactors as it can be used to produce fusion energy and breed fusion products. Lithium hydride and lithium deuteride may serve as good ablating sleeves for plasma formation in an ablation-dominated electrothermal plasma source to propel fusion pellets. Previous studies have shown that pellet exit velocities, greater 3 km/s, are possible using low-z propellant materials. In this work, a comprehensive study of solid lithium hydride and deuteride as a pellet propellant is conducted using the ETFLOW code, and relationships between propellants, source and barrel geometry, pellet volume and aspect ratio, and pellet velocity are determined for pellets ranging in volume from 1 to 100 mm3.

The research had used the metallized plastic of the ABS + 20wt%PC / Al flake with three different weight percentages (20wt5, 27wt%, 33wt5). Using the design of three - zone screw in the injection molding, and get the average aspect ratio of Al flake is 156. Using the design of progressive screw in the injection molding, and get the averge aspect ratio of Al flake is 198. Using the injection molding to get the tensile, impact and shielding test specimens, and discussing the microstructure and the effect of the content and aspect ratio of Al flake. From the result, the Al flakes are piled up easily in the injector, and the degree of piling up increases by adding the content of Al flake. In the EMI testing specimen, the pile - up situation is modified in the fanshaped runner and the sheet gate, but there are still clusters of Al flake in the gate (single pointed gate) of the tensile and impact. The impact strength, shielding effectiveness and HDT are increased with the rise of aspect ratio, but the volume resistivity and tensile strength go opposite. The HDT and the shielding effectiveness are increased with the adding of the content of Al flake, but the volume resistivity, tensile strength, and impact strength go contrary.
