The DMCG powering is provided by an energy preamplifier (helical MCG). Having a lot of contact connections located on a small radius, it is necessary to power the DMCG during a short time period; that is the preamplifier should be of high-speed. In the report, there are the results of the first experiment with a high-speed helical MCG with an internal diameter of the turns of 320 mm. The generator provided the current of 8.5 MA (magnetic energy of 10.6 MJ) with a characteristic rise time of 38 µs in the load of 300 nH at the energy powering of 120 kJ; this is equal to the initial inductance of the 15-element DMCG with a HE-charges of 480 mm diameter.","PeriodicalId":207949,"journal":{"name":"2018 16th International Conference on Megagauss Magnetic Field Generation and Related Topics (MEGAGAUSS)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128248492","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}
