Calibration of the E683 main calorimeter (electromagnetic hadronic calorimeter)

Abstract

The calibration of an electromagnetic-hadronic calorimeter is discussed in the larger context of the physics goals of the experiment in which it was used. Descriptions of the experimental apparatus are given. The methods employed for balancing electromagnetic response are discussed, including cuts on data integrity and fiducial cuts on energy distributions, and the reliability of the balancing algorithm. Results for energy resolution are given and are found to be in reasonable agreement with expectation. Extension of these balancing methods to hadronic response is discussed along with preliminary results. The ratio of hadronic to electromagnetic response is considered and is found to be in reasonable agreement with expectation. Methods of measuring and correcting for the calorimeter's evolution through time are briefly discussed.
