(MLI) has designed, delivered and tested power supplies rated at 240 kJ/s, 50 kV and 120 kJ/s, 30 kV to DLR for use in a high-power, pulsed CO/sub 2/ laser. The optical performance of this electron-beam sustained laser with an active volume of 20 liters and a transversal gas flow is strongly dependent on the shot-to-shot repeatability of the power supply(s). Testing of the power supplies was performed by operating the electron-beam and main discharge pulse forming networks (PFNs) into a resistive load at the maximum repetition-rate of the laser, 100 Hz, for the rated burst length of 1000 pulses. The PFN was switched using a rep-rate spark gap pressurized with compressed air to less than 3 atm of pressure. The regulation (shot-to-shot repeatability) of the 240 kJ/s supply operating at 40-45 kV was </spl plusmn/0.05%. This regulation was achieved through the use of a modular power supply design using 12 kJ/s CCDS switching power supply modules. In addition to the patented high regulation topology of the individual CCDS units, the key to achieving the high regulation is reducing the size of the quantum of charge delivered at the end of the charging cycle. The techniques used to assure graceful degradation (unplanned downtime minimization), high regulation and user friendly assembly as well as the technique for parallel control of tens of modules are discussed in this paper. In addition, a comparison of the practical limitations, advantages and disadvantages of this technique verses conventional 60 Hz approaches are discussed.","PeriodicalId":11163,"journal":{"name":"Digest of Technical Papers.

We have designed a low-cost modular photoemissive detector designated the XRD-96 that uses commercial 1100 series aluminum for the photocathode. In addition to photocathode detectors a number of designs using solid state silicon photodiodes have been designed and fielded. We also present a soft X-ray time-integrated pinhole camera system that uses standard type TMAX-400 photographic film that obviates the need for expensive and no longer produced zero-overcoat soft X-ray emulsion film. In a typical experiment the desired spectral energy cuts, signal intensity levels, and desired field of view will determine diagnostic geometry and X-ray filters selected. We have developed several computer codes to assist in the diagnostic design process and data deconvolution. Examples of the diagnostic design process and data analysis for a typical pulsed power experiment are presented.","PeriodicalId":11163,"journal":{"name":"Digest of Technical Papers.

First is the multi POS design with the number of the switches being equal to the number of the modules. The main advantages of this design are the possibility to perform the full scale investigation of the single module prototype including the POS before the total system will be built, and the possibility to increase the power of the system by adding some number of the well known elements. The main disadvantage of the multi POS design seems to be the jitter in the switch openings-the problem which is not solved at present. The second, single POS design, presumes one POS switching the energy from all the modules into the load. The main advantage of the design is the absence of the POS synchronization problem. In the same time the single POS design requires building of the total system before the POS could be tested resulting in a risk of worse opening or some other problems which may appear at increased POS current level. The GIT4-GIT8 facilities at HCEI represent a test bed allowing investigation of the single POS design at successively increasing POS current (2.5-5 MA). The goal of the experiments described was to clear the current distribution in the switch region on GIT8 and to determine possible restrictions which could limit the application of the given single POS design.","PeriodicalId":11163,"journal":{"name":"Digest of Technical Papers.
