Construction and Performance of the Barrel Electromagnetic Calorimeter for the GlueX Experiment

Understand

The barrel calorimeter is part of the new spectrometer installed in Hall D at Jefferson Lab for the GlueX experiment.

• The calorimeter was installed in 2013, commissioned in 2014 and has been operating routinely since early 2015.
• The detector configuration, associated Monte Carlo simulations, calibration and operational performance are described herein.
• The calorimeter records the time and energy deposited by charged and neutral particles created by a multi-GeV photon beam.
