Development of Integrated SOL/Divertor Code and Simulation Study in JAEA
Hisato Kawashima,Katsuhiro Shimizu,Tomonori Takizuka,S. Sakurai,Tomohide Nakano,Nobuyuki Asakura,Takahisa Ozeki +6 more
TL;DR: An integrated sol/divertor code is developed by the JAEA (Japan Atomic Energy Agency) for interpretation and prediction studies of the behavior of plasmas, neutrals, and impurities in the SOL/Divertor region as discussed by the authors, which can obtain a steady state solution within 3 ˜ 4 hours even in the first run of a series of simulations, allowing the performance of an effective parameter survey.
