Design of ex-vessel magnetic probes for JET-EP

摘要: Abstract A new magnetic diagnostics system has been designed for the 2005 JET experimental campaigns onward. The system, which is integrated into existing diagnostics, consists of in-vessel and ex-vessel sensors, intended to provide an improvement in accuracy reliability present equilibrium reconstruction iron modelling capabilities [V.
