The electron emission from a field emission trigger unit was matched to the requirements for the simultaneous ignition of all channels in a radial multichannel pseudospark switch for a large parameter range of the pseudospark discharge. In such trigger unit the electrons are extracted from the surface of a high-e material by field emission after applying a pulsed voltage. Electron emission occurs in a pressure range from 1-50 Pa, where the pseudospark discharge is operated. The access to low working gas pressures (
