One of the major design parameters for the design of thermal shield cryopanel and supports is the eddy current induced during plasma disruption. The eddy current creates joule heating as well as electromagnetic (EM) loads combining with magnetic fields. Since the cryopanel should be maintained at a cryogenic temperature lower than 80 K, even a small amount of joule heating may play an important role in increasing the cyropanel temperature. Also the EM loads are very critical mechanical forces for the design of structure of the thermal shield, especially for the supports. Joule heating and EM loads on the vacuum vessel thermal shield during plasma disruption were calculated to provide the design requirement of the thermal shield. Based on the joule heating and EM loads, the structural and thermal stress analyses were performed for the assessment of the structural robustness of the vacuum vessel thermal shield. It was found that the effect of joule heating on the thermal shield design is minimal, but the EM loads are important for the design of cryopanel as well as supports. The optimal number and size of supports were determined.","PeriodicalId":44192,"journal":{"name":"NINETEENTH CENTURY MUSIC","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85505740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"艺术学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was shown that a dimensionless local parameter, /spl rho//spl dot/(T/sub e/) =/spl rho//sub s//L(T/sub e/) characterises with a low computational cost the typical ITB features such as the emergence time, location, collapse time and dynamics [/spl rho//sub s/ is the local Larmor radius and L(T/sub e/) is the temperature gradient scale length L(T/sub e/)=-T/sub e//(/spl part/T/sub e///spl part/R)]. We report on the recent implementation of the calculation of the ITB criterion together with the associated feedback algorithms in the real time system of JET. The system purpose is to acquire all the analogue channels of the high space resolution electron temperature ECE diagnostic (heterodyne radiometer) and to calculate in real time the relevant ITB parameters which am used for the control: the maximum value of the dimensionless local temperature gradient, the ITB radius and width, the core and volume averaged electron temperature.","PeriodicalId":44192,"journal":{"name":"NINETEENTH CENTURY MUSIC","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89776912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"艺术学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
