Description
The Heavy Ion Beam Probe (HIBP) diagnostic is known as a unique tool for the direct plasma electric potential measurements. The method is based on the injection of single charged ion beam into the plasma and the registration of the double charged particles born due to collisions with the plasma electrons. Three schemes have been analysed: Cs+, Tl+ ion and neutral injection for TCABR parameters: B0 = 1.5 T, Ipl = 135 kA. The calculations show that ion probing allows getting radial profiles of TCABR plasma parameters with the injection angle fast scan system. In all cases of ion beam injection we must use a curved beam line for ion beam transportation from last alpha-steering plates towards upper port. The primary ion beam injector must be situated out of high magnetic field area and its length is about 1.5 m. The energy range (less than 100 keV for Cs+, or Tl+) allows using compact and cheap ion gun equipment
