The CLAS Cerenkov Detector

As of 28 January 1998, the last of the six CLAS Cerenkov detectors has been installed. Now, it's time for some documentation. This document came into being on 29 January 1998; as of this writing, it is still 29 January 1998. So, there isn't much here yet.

This introduction is in lieu of having that ubiquitous image of a construction worker saying "This page under construction".

Introduction

The Cerenkov detector was built by Rensselaer Polytechnic Institute (RPI), with significant technical assistance by Jefferson Laboratory. The calibration software is being written by John Price of RPI, and the reconstruction software is being written by Alexander Vlassov and Alexi Stavinsky of ITEP (Russia). Each of its 216 independent channels consists of a Philips 5" photomultipliertube (PMT) and three specially-constructed mirrors. The overriding principle of the detector is to collect a large fraction of the Cerenkov light while using the minimum amount of material, which can degrade the energy reconstruction of the calorimeters.
