HIBP diagnostic injectors for Uragan-2M and TJ-II stellarators

The testing and first operations of the Heavy Ion Beam Probe (HIBP) plasma diagnostic injectors for stellarator Uragan-2M and TJis presented in this work. The increasing of plasma density in modern fusion devices up to (3...7)×10 m (TJand T-10) leads to huge probing ion beam absorption in central plasma area. One way to obtain the HIBP information from plasma centre is the increasing of primary ion beam current. A new modification of HIBP injectors for TJand Uragan 2M stellarators was developed and tested in IPP NSC KIPT with energy up to 100 keV and ion current up to 300 μA. PACS: 52.70.Nc
