Hardware implementation and testing of 4-channel fast electronics for a MCP detector

Using the Quartus software environment, simulation of time measurements for a fast collision monitor of particle beams based on chevron MCP assemblies was carried out. The measurement algorithm is based on the delayed coincidence method. 4-channel electronics for a detector on microchannel plates (MCP) based on high-speed comparators and FPGA EPM240 from ALTERA have been created. The test prototype was tested using a 4-channel nanosecond pulse generator, with an adjustable delay between channels. When using these comparators and FPGAs, it is possible to determine the time of registration of particles by a detector with an error of 100 ps, while the calculated speed of the reading circuit coincides with the measured one and is no more than 10 ns for each event for a 4-channel system.
