abstract: eTOF is a forward time of flight (TOF) detector upgrade to the STAR experiment
at the rRelativistic Heavy Ion collider (RHIC). The eTOF program is a collabo-
ration between STAR and the Compressed Baryonic Matter(CBM) experiment
at FAIR. The eTOF wheel consists of 108 CBM-TOF multi-gap resistive plate
chamber (MRPC) prototypes. For CBM, eTOF is the first large-scale test of its
MRPC prototypes and its free-streaming data acquisition system (DAQ). For
STAR, eTOF extends the forward acceptance of its time of flight system for par-
ticle identification (PID). These extended PID capabilities are important for the
analysis of STAR’s Beam Energy Scan II campaign, especially the in the fixed
target program. The MRPC prototypes have shown no significant aging over
an operation time of more than two years. An average system time resolution
of 70.7 ps with a spread of < 4.3 ps RMS between the individual MRPC time
resolutions is achieved. The track matching efficiency of eTOF is close to 70 %.
