Description
The time-of-flight method of particle identification in the MPD multi-purpose detector is one of the main methods for identifying charged hadrons in the momentum range up to 3 GeV. It is necessary that the time-of-flight system detectors have the best time resolution with an efficiency close to 100% for highly efficient registration and separation of kaons and pions with a limited time-of-flight base. A multi-gap resistive plate chamber (MRPC) with 15 gas gaps was developed for this purpose. The best time resolution of the MRPC with front-end and digitizing electronics reached 40 ps with a detection efficiency of 99%. Such a detector is fully satisfied with the technical and physical requirements of the MPD experiment.
The report will present the testing results of the MRPC prototype and the results of the simulation of the properties of the time-of-flight system assembled from these detectors.
