LTD based drivers are considered for many applications including future very high current Z-pinch drivers like ZX and Z-pinch IFE (Inertial Fusion Energy). The salient feature of the approach is switching and inductively adding the pulses at low voltage straight out of the capacitors through low inductance transfer and soft iron core isolation. Utilizing the presently available capacitors and switches we can envision building the next generation of fast z-pinch drivers without the usage of large deionized-water and oil tanks as it is the case with the present technology drivers. The most significant advantage of all is that the LTD drivers can be rep-rated. The later makes LTD the driver of choice for z-pinch IFE where the required repetition rate is of the order of 0.1 Hz. Presently we have in rep rated operation in Sandia a one 500-kA, 100-kV LTD cavity. The compact fast (≪100 ns) LTD was suggested and its development is funded by Sandia at the High Current Electronic Institute (HCEI) in Tomsk, Russia, where a number of larger and stackable 1-MA cavities are under construction.","PeriodicalId":338246,"journal":{"name":"2006 IEEE International Conference on Megagauss Magnetic Field Generation and Related Topics","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126051320","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}

Sharing similarities with the GEPI pulser [2], a compact pulser has been designed and built, focusing on Isentropic Compression Experiments. In order to achieve high compacity and fast turn around, the design is built around a solid dielectric transmission line to couple current from eight low-inductance capacitors that are switched with ultra-low-inductance multi-channel gas switches operating in dry air at atmospheric pressure. A peaking stage made of 72 capacitors enhanced by a low inductance, multi-channel sharpening switch brings the fundamental rise time of the pulser down to 350 ns (10-90%). A set of inductances in parallel with the sharpening switch as well as using various gases into this switch allow us to modify the current wave shape. The pulser delivers a peak current of 4 MA at a charge voltage of 80 kV on a short circuit. The rise time can be lengthened to around 650 ns for a current of 4.2 MA. The use of post-holes convolutes in a solid dielectric insulation design makes that pulser unique as well as its compact size, ease of use and ease of access to the load.","PeriodicalId":338246,"journal":{"name":"2006 IEEE International Conference on Megagauss Magnetic Field Generation and Related Topics","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116090203","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}

This quest has often achieved success with some form of liner implosion technology, but not in the actual compression of plasma. Several plasma targets have been proposed, ranging from plasma magnetized to reduce heat transfer, but mechanically-supported by the liner, to plasmas confined and supported by magnetic field, in some configuration of open and closed field-lines. In all cases, the principal issue remains one of preventing the high atomic-number material of the liner from penetrating the plasma and countering the gain in plasma temperature sought by compression. Two factors foster development of such deleterious penetration: the creation of a liquid/vapor layer at the liner surface at high magnetic fields, and disruption of this layer by Rayleigh-Taylor instability in the final stages of plasma compression. The latter factor, of course, depends on the desired efficiency of energy transfer from liner kinetic energy to the plasma. In reactor concepts, the efficiency needs to be high in order to reduce the total system energy and size to attractive values. Within a general review of issues of liner compression of plasma, we discuss reactor cost optimization by use of plasma at pressures intermediate between the values of conventional magnetically- or inertially-confined fusion concepts. We also describe the development of an equilibrium layer of vapor adjacent to the liner surface at high magnetic fields, and the consequences of liner deceleration and rebound for reactor concepts and research progress.","PeriodicalId":338246,"journal":{"name":"2006 IEEE International Conference on Megagauss Magnetic Field Generation and Related Topics","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121292463","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}

The Z DH source produces as much as 100 kJ with powers up to 17 TW into a 4-mm diameter, axially-located radiation exit hole above the source. The Sandia Laboratories¿ ZR upgrade of Z may be able to similarly produce 200 kJ. The complex Z DH radiation source varies in spectral power and timing from shot-to-shot. We are characterizing the source physics through simulation and experiment in order to minimize this variability. We are studying how the complex spatially and temporally-dependent behavior of the DH source affects the performance of a number of axially-located experiments. Using the Z DH as a source, we developed the new blast wave diagnostic, and applied it in a number of novel experiments. A large number of physics issues can be addressed by the Z DH and blast wave diagnostic, including experiments to study opacity, radiation transport and hydrodynamics. We will show how some experiments are quite sensitive to the source details while others are much less so. A synopsis and analysis of recently completed experiments as well as proposals for future work are presented.","PeriodicalId":338246,"journal":{"name":"2006 IEEE International Conference on Megagauss Magnetic Field Generation and Related Topics","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115505709","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}
