HIISI

 Ion beams were produced with HIISI:

HIISI was tuned for Xe27+/Xe35+ ion beams using 3-frequency operation mode. The power was distributed as follows: 2000 W(18 GHz)+750 W (17.4 GHz)+250 W (14.5 GHz). Oxygen was used as a mixing gas. The extraction voltage was 16 kV (4 mA). Other tuning parameters:

Bias disk voltage: -20 V (0.6 mA).

Injection coil/middle coil/extraction coil: 1000 A/-140 A/860 A. Magnetic field values were about 2.8 T/0.45 T/1.36 T, respectively.
