STAR Time-Of-Flight Patch
(TOFp/pVPD)

NIM Paper
(submitted 6-23-2003)
   

We proposed the construction of a single tray of highly segmented Time-of-Flight detecters and the installation of this tray in STAR in time for operation in the first physics run of RHIC. The system covers approximately one unit of pseudo-rapidity and ~5.3 degrees in azimuth with 41 single-ended plastic scintillator slats. At the heart of the system are custom high-performance leading-edge discriminators with remote threshold control inside the tray. When in STAR, the system will provide velocity information for reconstructed tracks that extends, and nearly completes, the hadronic particle identification capabilities of STAR. High efficiency direct identification of pi and K mesons is possible up to ~1.8 GeV/c, while protons can be positively identified with high efficiency at momenta up to ~3 GeV/c. The system thus plays a positive role in a number of fundamental "spectra" physics analyses in STAR. It also allows important consistency tests of the performance of each of the various particle identification approaches available in STAR.
