Abstract

The coincidence experimental setup for studying multiple electron processes at low energies established at the Institute of Modern Physics was presented. The setup includes time-of-flight spectrometer, position sensitive detector, and multi-parameter data acquisition system. Presented were a TOF spectrum for Ar12+ on Ar collisions, a position spectrum obtained in O2+ + He collisions, and a two-dimension spectrum for Ar8+ + Ar collisions at 104 keV. The experimental results were analyzed in detail and 12 subprocesses were identified from the two-dimension spectrum.
