Performance of the Front-End Electronics of the PADME charged particle detector system

Abstract

The PADME charged particle detector system should detect positrons and electrons with efficiency better than 99 {\%} and time resolution below 1 ns. The system hosts about 200 readout electronics channels whose operation has to be verified and commissioned. A custom based test system allowing to perform qualitative check of the produced frontend electronics has been developed and was used to test a total of 256 channels. The obtained time resolution was found to be consistent with the requirements and better than 500 ps for all the channels.
