The MICE PID Instrumentation

TL;DR

The MICE experiment develops advanced particle identification instrumentation, including time-of-flight, Cerenkov detectors, and calorimetry, to precisely measure muon beam emittance and contamination in challenging experimental conditions.

Contribution

This paper introduces a comprehensive PID system for MICE, combining multiple detectors to achieve high-resolution particle timing and contamination suppression.

Findings

Time-of-flight resolution better than 70 ps per plane

Contamination kept below 1% with the new PID system

Effective operation in high-rate, magnetic, and background environments

Abstract

The international Muon Ionization Cooling Experiment (MICE) will carry out a systematic investigation of ionization cooling of a muon beam. As the emittance measurement will be done on a particle-by-particle basis, sophisticated beam instrumentation is needed to measure particle coordinates and timing vs RF. A PID system based on three time-of-flight stations, two Aerogel Cerenkov detectors and a KLOE-like calorimeter has been constructed in order to keep beam contamination ($e, \pi$) well below 1%. The MICE time-of-flight system will measure timing with a resolution better than 70 ps per plane, in a harsh environment due to high particle rates, fringe magnetic fields and electron backgrounds from RF dark current.
