TWIST Technote 58

Status and Tests of the Capacitive Probe Time of Flight for Particle ID

Blair Jamieson, March 2002

In this document, the circuit used in November 2001 to produce a time of flight with the CP signal (CP-TOF) will be described. The method of selecting muons from the CP-TOF spectrum will be reviewed. Finally, by using information from the Proportional Chambers (PCs) in the TWIST spectrometer, two simple tests of particle identification by the CP signal will be presented.

This document is not intended to be a comprehensive study of TOF, but rather it is a status report on the state of the time of flight in November 2001 data.
