Abstract :
We report on results of efficiency tests for MIPs and timing resolution studies obtained with different layouts of micro-channel plate (MCP) detector prototypes at CERN PS test beams. The detector is composed of an MCP stack and multipad readout anodes integrated with a passive isochronal summator. Several types of setups were tested, including MCPs with different gain. Also, a very first test of the Micro Sphere Plates detector was performed. The performance of fast electronics including Double Threshold Discriminators and a fast multiplicity discriminator for short 2 ns signals was studied. Currently, the best experimental results for MCP detectors show 75 ps timing resolution obtained at 75% efficiency for the registration of a single muon. We expect further enhancements, mostly through improvements in the fast electronics.
