Among the observed resonance transitions the cyclotron resonance and combined resonance were identified. The g-tensor is not proportional to the macroscopic magnetization in its T- and B-dependence. In addition, transitions are observed which extrapolate to a finite binding energy.","PeriodicalId":314918,"journal":{"name":"1983 Eighth International Conference on Infrared and Millimeter Waves","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121081611","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}

Theoretical results will be presented on the design and performance of the two high power gyrotrons that will be used in these experiments. Both resonant structures employ a complex cavity configuration which was conceived to alleviate the problem of mode competition. The first gyrotron consists of a TE031-TE041 combination with an output power of 0.5 MW, while the second gyrotron consists of a TE031-TE061 combination with an output power of 1 MW. Both gyrotrons operate at 100 GHz. Results will be presented on the starting currents in the presence of magnetic tapering and on the optimal operating conditions of each device.","PeriodicalId":314918,"journal":{"name":"1983 Eighth International Conference on Infrared and Millimeter Waves","volume":"285 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124215486","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}
