The Spherical Tokamak MEDUSA for Costa Rica
POSTER
Abstract
The former spherical tokamak (ST) MEDUSA (Madison EDUcation Small Aspect.ratio tokamak, R$<$0.14m, a$<$0.10m, B$_{T}<$0.5T, I$_{p}<$40kA, 3ms pulse)[1] is in a process of donation to Costa Rica Institute of Technology. The main objective of MEDUSA is to train students in plasma physics /technical related issues which will help all tasks of the very low aspect ratio stellarator SCR-1(A$\equiv $R/$\langle $a$\rangle \ge $3.6, under design[2]) and also the ongoing activities in low temperature plasmas. Courses in plasma physics at undergraduate and post-graduate joint programme levels are regularly conducted. The scientific programme is intend to clarify several issues in relevant physics for conventional and mainly STs, including transport, heating and current drive via Alfv\'{e}n wave, and natural divertor STs with ergodic magnetic limiter[3,4].
