The application presents efficiency, lifetime and cost challenges that mandate the use of advanced pulse compression topologies. In turn, these advanced topologies require the development of critical components and the establishment of engineering criteria for use in designing them. The component most critical to realizing any of the advanced topologies under study is the primary energy transfer switch. Therefore, the program has been developing an advanced optically-triggered and pumped solid state switch that is expected to meet the efficiency, lifetime and cost requirements of an IFE driver. Liquid dielectric breakdown studies are also underway, with the intent to develop design criteria relevant to the large electrically stressed areas associated with a viable KrF IFE power plant. KrF IFE pulse compression and component concepts are discussed as well as the most recent results from the solid-state switch development and liquid dielectric test efforts.","PeriodicalId":339166,"journal":{"name":"Conference Record of the Twenty-Fifth International Power Modulator Symposium, 2002 and 2002 High-Voltage Workshop.","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127732819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By applying external electric fields along biological cells in a water suspension the cytoplasm becomes polarized. The charge displacement in the cytoplasm and in the suspension leads to high transmembrane potentials in the order of several volts. The build-up of large irreversible openings in the cell membrane, the flow-out of cytoplasm and the cell-perish are the desired effects. The subject of this paper is i) to report on experiments at an EP system with whole crop plants. Experiences have been gained already with sugar beets, apples, grapes, etc., ii) to present design studies for an industrial EP production device. The amount of plant material, which must be treated is in the order of 1 t/min. Since crop plants, such as sugar beets, are large in diameter and nearly weightless in water (suspension), the size of an EP reactor has to be large and the plants must be moved continuously by means of a forced feed-through. This requires very high voltage pulses to establish reactor field strengths of about 20 kV/cm in the 30 cm gap, as well as high pulse repetition rates to fulfill power demands. At the Forschungszentrum Karlsruhe several types of Marx generators with gas spark gaps have been developed and tested. They run with pulse frequencies in the order of 20-30 Hz. The pulse amplitude is 300 W, the pulse length is 1 /spl mu/s and the pulsed energy fed into a 20 load is about 1 kJ. The lifetime of the electric components is designed to withstand at least up to 200 million discharge cycles (3 month operation). The system consisting of the EP reactor plus conveyance is designed to be built up mainly of dielectric materials to avoid undesired shielding effects of the electric field in the area of the reactor chamber. However high voltage-proof dielectric materials such as polyethylene or polypropylene underlie enhanced mechanical wear which must be taken into account.","PeriodicalId":339166,"journal":{"name":"Conference Record of the Twenty-Fifth International Power Modulator Symposium, 2002 and 2002 High-Voltage Workshop.","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133666622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SAS had long turn off time due to the minority carriers existence after the turn on process. Circuits, which were used to modulate SAS, with power modulator thyristors as primary switches, could not provide the efficient work at high PRF. We overcame these limitations by use on the next means. The specially doped series of SAS, which combine fast turn on time and low jitter with high reliable work at tens kpps repetition rates, has been developed, tested and produced. The new control circuit schematic, based on drift step recovery diodes (DSRD) and transistors (DSRT), has been designed. This circuit is able to generate stable driving signals to switch SAS up to hundreds kpps. As a result, the developed power pulse generator has the following parameters: output pulse amplitude (on 50 Ohms) 1 kV; rise time 80 ps; pulse width 220 ps; jitter <30 ps; maximal PRF 50 kpps; total power consumption at max. PRF <5W; lifetime 10/sup 11/ pulses and size (version with DC power supply) 110/spl times/50/spl times/40 mm. It should be mentioned that the high time stability of output pulses gives a possibility to combine total power of many generators into a load.","PeriodicalId":339166,"journal":{"name":"Conference Record of the Twenty-Fifth International Power Modulator Symposium, 2002 and 2002 High-Voltage Workshop.","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131727250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
