Calorimeters With Charge-Collection Readout

Abstract

This short review will be concerned with questions which arise in the design and construction of calorimeters whose common feature is that the signal is derived by drifting charge, deposited in a sensitive medium by showers induced by the interaction of photons, electrons or hadrons, under the influence of an electric field. This broad definition encompasses a variety of distinct technologies: sampling calorimeters in which the sensitive medium is liquid argon (SLD, D0, E706 [1], H1, HELIOS), a room-temperature liquid (UA1), high-resistivity silicon (H1, SLD) and fully-absorbing devices such as the KEDR electromagnetic calorimeter, which uses liquid krypton. Using examples drawn from the work of these groups, I will deal with several general issues affecting the design of charge-collecting calorimeters.
