Cosmic ray tests of a liquid argon calorimeter

University of British Columbia

A series of tests have been performed on a liquid argon calorimeter module at the Test Beam Facility at the Stanford Linear Accelerator Centre. We find that the calorimeter performs according to design. Several performance parameters have been measured. The charge-collection efficiency in a tower of the calorimeter was observed to be 87%. This loss is due mainly to recombination; absorption by oxygen impurity seems insignificant. No detectable energy loss has been observed when a particle moves through the crack between adjacent towers. The cross-talk between two adjacent towers was measured and found to be in agreement with a simple model.
