Abstract

We describe a time-of-flight electron spectrometer designed for measurements of the energy spectra of the electrons emitted in the forward direction in ion-atom collisions. The most important part of the spectrometer is an electrostatic mirror. The electrons ejected in a small angular range (typically ±1°) around 0° from a gas jet target by a well-collimated ion beam are reflected by the mirror into backward angles. Following the reflection, the electrons fly in a field-free space until they reach the detector. The time-of-flight of the electrons elapsed between their emission and detection is measured by detecting the electrons in coincidence with the charge-state analysed outgoing projectiles. Results of test measurements carried out for collisions of 200-350 keV Cq+ (q ≤ 1, 2) ions with Ar atoms are presented.
