Abstract—A compact neutral particle analyzer that has been modified for studying thermal and suprathermal ions in neutral-beam heated plasma is described. Results of the analyzer calibration performed using an atomic beam are presented. The possibility of adjusting the analyzer channel energies by varying the voltage applied to the acceleration module of the analyzer is tested. The measured ion temperatures and suprathermal-ion spectra are presented for discharges with the neutral beam injection at the TUMAN-3M tokamak.
