Abstract
The design, construction, and performance of a hexagonal-nose-cone-shaped plastic scintillation counter system is described. This “Start Counter” is used as part of the trigger and to measure event start times for photon beam running with CLAS in Hall B at the Thomas Jefferson National Accelerator Facility. The Start Counter is constructed of three 3-mm thick coupled-paddle scintillators and achieves a software-corrected time resolution of 260 ps. Each coupled-paddle scintillator operated without appreciable sagging up to ∼1.2 MHz rate.
