Abstract

A time of flight system for the analysis of low energy neutral hydrogen emitted from ASDEX is described. The neutral flux from ASDEX is chopped in bunches of 1 /us by a slotted cylinder driven by a modified turbo pump. After a flight path of 2 m the particles are detected by a secondary particle detector. Single particle pulses are collected in a multichannel analyzer in the MCS mode with a time resolution of 1 /us. Differential neutral emission spectra are calculated from the arrival time distributions. A number of results are presented to demonstrate the capabilities of the instrument.
