Full textHigh-energy electron beams, with electron kinetic energies (∼1 MeV) much greater than the surrounding plasma temperature (<1 keV), are a common feature in Z-pinch pulsed power experiments. Their existence is indicated by non-thermal spectral signatures, such as high-energy Bremsstrahlung photons from the anode hardware and characteristic X-ray emission not representative of the pinch "hot-spot" temperatures. Despite their regular occurrence, the properties of these beams (kinetic energy, current) are not well known.
This dissertation describes an experimental study of X-pinch generated high-intensity electron beams, performed on the 1 MA pulsed power generator at the Nevada Terawatt Facility, and the feasibility of a novel method for inferring the total kinetic energy in the beam, through time-resolved measurements of the beam-induced shock that propagates through the anode.

Full textIt is shown that the system can be improved considerably by modifying the gas puff design. Three gas puffs developed in this work are optimized for x-ray emission from argon, krypton, and neon gases. In the optimized conditions the output x-ray energies of 0.5 J from Ar-K shell, 2 J from Kr-L shell, and more than 2 J from Ne-K shell are obtained.
The implosion dynamics is studied with different gases under varying conditions. The average implosion velocity, the final pinch diameter, the current waveform, and the emitted x-ray energy are measured. The pinched plasma parameters such as temperature, density, and the average ionic state are estimated using the corona model calculations, and the pinched current waveforms. The spectrum of the neon radiation clearly shows the characteristic H-like and He-like lines. The neon spectrum is used to estimate the plasma temperature.
The dynamic performance of the magnetically induced compression gas puff is studied carefully. A special ion probe was developed for studying the dynamic parameters of the gas puff. The ion measurements with the probe have led to the characterization of the gas puff performance under varying operating conditions. It is shown that ions are generated through photoionization of the injected gas by the UV light emitted from the inside of the gas puff plenum through the nozzle. It is found that the jet velocity and ion density can be in excess of $3 times10 sp3$ m/s and $2 times10 sp{14}$ cm$ sp{-3}$, respectively.
A theoretical model is developed to simulate the plasma evolution in the gas puff. This model uses the magneto hydrodynamic (MHD) equations solved by the finite difference method. The magnetic field in the vacuum is calculated using the Laplace equation and self consistent boundary conditions. The model predicts the evolution of plasma variables such as density, temperature, velocity, and magnetic field. It also calculates the variation of the total mass flow rate, optical output, and the ionic signal. The simulation results are shown to compare favourably with the experimental measurements.

Full textPolymorphic transitions and melting of tin were studied under dynamic loading by coupling velocimetry and X-ray diffraction in order to determine transition pressures and to identify phases in presence. In the literature, different onset pressures were measured for the β-γtransition between static and dynamic loading, and even for one same loading type. Thus, further work is needed to characterize the formation conditions of the γ phase: in-situ X-ray diffraction provides data on microstructure evolution in time, on phases in presence, on orientational relationship and on the kinetics of the transformation. These data can be used totest theoretical hypotheses on the transition mechanisms, kinetics, and possible twinning. Previous impact experiments were performed at CEA Gramat and at Advanced Photon Source(APS) facilities, on single crystal tin of (110) orientation with a launcher and a short X-raysource. The present investigation is a continuation of that exploratory study based on an optimized configuration to highlight the γ phase from three orientations of the β phase: (110),(100) and (001). Shock experiments were performed at CEA Gramat with an X-Pinch generator to obtain X-ray diffraction patterns both under shock compression and in release. For each orientation, varying the time delay between the shock and the X-ray probe allowed studying the evolution of diffraction patterns directly correlated with microstructural modifications and transition kinetics. Complementary shock experiments were performed at the synchrotron facilities of APS to probe a time-resolved evolution of the sample for each shot, which provided additional results. These data enable to propose kinetic hypothesis for the transition between β and γ. Furthermore they are consistent with the theoretical mechanism which was validated in quasi-static anvil cell experiments recently. Other direct and reverse transitions between β, γ and δ phases as well as melting on release were observed according to the applied pressure. All these results build up a database to improve multiphaseequations of state used in simulations of dynamic processes

Full textIn order to study the feasibility of creating an intense X ray source for France, the Centre d'Études de Gramat (CEG) is investigating several technologies. The Syrinx project is looking at the potential of High Pulse Power technologies for Isentropic Compression Experiments, High Temperatures Hohlraums and Radiation Hardening (X rays between 1 eV and 10 eV radiated by a Z-pinch). Then it is necessary to provide a power amplification stage allowing electrical currents of the order of 10 MA with a hundred nanoseconds rise rime to be delivered to the load. Usually, generators use pulse forming lines or plasma opening switches. Magnetic Flux Compression, another power amplification possibility, is studied in this dissertation. It has enabled the compression of the 100 ns pulse of the Z machine (Sandia National Laboratories) into a 40 ns pulse and the compression of the 1 ms pulse of the ECF generator (CEG) into a 100 ns pulse. This technology bas the advantage of a characteristic implosion time less than a micro second avoiding many of the problems the explosive driven flux compression ran into. This research work consisted initially in finding the right parameters for several codes (circuits codes, plasma codes. . . ) in order to adapt them to the Flux Compression. These numerical tools have then been used to design experiments on Z and ECF. These experiments have reached 5 Mbar with shock and more than 2 Mbar in isentropic compression as well as 110 eV in a hohlraum. Insights gleaned from the interpretation of the shots have been compared to our understanding of the power amplification system and of the loads. Finally, this allows us to improve our numerical tools and to optimize the Flux Compression concept. The work which has been done should lead to the extrapolation of the concept to an X ray generator of the 60 MA class
