Abstract

It was shown experimentally that delayed signals from the spark counters (''tail problem'') could be connected with low gain avalanches. The development of these avalanches is stopped by the anode electrode but they still have a chance to produce a delayed streamer by photon feedback. Good absorption characteristics of the gas mixture at wide photon energy range (starting from a cathode work function up to the X-ray region) and a high cathode work function value reduce the tail.
