Description
The GRINCH is a new heavy gas chereknov threshold detector developed for the Super Bigbite (SBS) program in Hall A in Jefferson Lab. The purpose of the GRINCH is to distinguish between pions and electrons during electromagnetic form factor scattering experiments in the SBS program. Consisting of 510 1-in photomultipier tubes and filled with $C_4 F_8 O$ heavy gas, this novel detector is designed to run in very high background rates. The GRINCH began commissioning with beam during the $G^n_M$ experimental run in Hall A in January 2022. This talk will give an overview of the GRINCH detector, analysis of its performance during the commissioning period using cluster finding methods, and its future in Hall A experiments.
