In order to minimize the operating voltage of the pulse generator and to increase the discharge gap and hence the energy absorption by the plasma channel that leads to the fracture build-up, the electro-bursting cartridge (copper wire in polyethylene) was used. With the pulse amplitudes of ∼ (15–20) kV and wire length of ∼ (20–60) mm, concrete blocks of 700*450*300mm size can be fractured. Specific energy deposition of ∼ 60 kJ/cm3 leads to the pressure buildup of up to 2.5·109 Pa in the discharge plasma channel. Under the action of pressure, the highly conductive plasma channel expands and generates the shock wave, causing the mechanical stress formation in the solid. Elastoplastic deformations and radially propagating cracks are launched into the material and this leads to the sample fracture. The dynamics of the generator energy conversion into the plasma channel and into the wave of mechanical stresses in solid is considered. Electro-discharge fracture can be a cost-effective and practical solution for disintegration of the rock mass by splitting rock fragments off the free rock surface in mining, oil and gas, tunnel construction and similar applications.","PeriodicalId":331835,"journal":{"name":"2011 IEEE Pulsed Power Conference","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131450172","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 new design allowed to achieve up to ∼1.7 MA in plasma loads and up to 1.9 MA in static loads [1]. The previous LCM version provided 1.4 and 1.6 MA accordingly [2]. The load current increase results in the increase of X-ray yield and power from plasma radiation source loads [3]. The advanced LCM represents an integral part of Zebra, inside the generator vacuum section. The new low-inductance design of LCM-to-load connection ensured shielding of the multiplier convolute from load events. Experiments with plasma loads were thus possible without after-shot dismounting of LCM for load installation and diagnostics arrangement. Validation of LCM's on a high-voltage nanosecond generator suggests that the concept could be applicable to existing and future multi-MA fast pulse-power drivers. Anticipating these applications, we present first estimates supporting scaling-up of the LCM technique to multi-terawatt facilities.","PeriodicalId":331835,"journal":{"name":"2011 IEEE Pulsed Power Conference","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134501510","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}

Statistical analysis of the breakdown voltages associated with such liquid-solid interfaces can reveal useful information to aid system designers in the selection of solid materials. Described in this paper are the results of a Weibull statistical analysis, applied to breakdown voltage data generated in gaps consisting of five different solid polymers immersed in mineral oil. Values of the location parameter γ provide an estimate of the applied voltage below which breakdown will not occur, and under uniform-field conditions, γ varied from 192 kV (480 kV/cm) for polypropylene to zero for ultra-high molecular weight polyethylene (i.e. the data for UHMWPE were better described by a two-parameter distribution). Longer times to breakdown were measured for UHMWPE when compared with the other materials. However, high values of the shape parameter β reported in the present paper suggest greater sensitivity to an increase in applied voltage - that is, the probability of breakdown increases more sharply with increasing applied voltage for UHMWPE compared to the other materials. Only PP consistently reflected a low value of β across the different sets of test conditions.","PeriodicalId":331835,"journal":{"name":"2011 IEEE Pulsed Power Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133040185","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}
