Summary of Objectives
This is the summary of our test-beam goals for one week of beam time (Sep. 22-30, 2006) delivered to Hall-B during the period in 2006 when the CEBAF accelerator is running at 687 MeV. The electron beam will produce a photon beam using the Hall-B tagger system. Photons of various energies will be used to measure the response of a 4-m-long lead, scintillating fiber (Pb/SciFi) prototype module for the GlueX barrel calorimeter (BCAL). The 687 MeV endpoint energy will provide the minimum photon energies needed for these tests. The module will be mounted on a support system in the Hall-B alcove area. The module will be illuminated at several positions along its length and at several angles, from 0-80 degrees with respect to normal incidence. The data will allow us to measure energy resolution, time resolution and linearity and will also allow a validation of our Monte Carlo simulations.
Calibration
The initial calibration of the BCAL prototype module (Module 1) will be accomplished using cosmics...
Beam
During the initial stages of beam in Hall-B, the BCAL will be positioned so that the beam impacts at its center, and at a 90 degree angle...
...work in progress, hope for a draft by August 26 -- zp
