Compensating hadron calorimeters with Cerenkov light
Many future high energy experiments anticipate the need for large compensated hadron calorimeters. The authors are attracted to homogeneous absorption calorimeters for hadrons by potential gains in simplicity, hermeticity, ease of calibration and a potential reduction in sampling fluctuations when compared to layered structures. However the excellent compensation possible by heterogeneous stacking of inert absorbers and active ionization layers is impossible in homogeneous calorimeters by the detection of ionization alone. Because only a small fraction (-- 10%) of the energy deposition in the purely hadronic portion of a hadron shower is by minimum ionizing particles, they have investigated the possibility of compensating calorimetry in homogeneous transparent materials by measuring separately the ionization energy (by scintillation or drifted ions) and the Cerenkov light, in order to separate the electromagnetic fluctuations in the shower, thereby correcting calorimeter response. They discuss potential media and methods to accomplish this, together with calculated responses. The advantages/disadvantages in construction, hermeticity, speed, radiation hardness, stability, segmentation, calibration, triggers, containment and simplicity are compared with SSC calorimeter plans.
