Drift Collection Calorimetry Using a Combined Radiator and Field Shaping Structure of Lead Glass Tubing

Abstract

A design for a drift collection calorimeter having a combined radiator and electric field shaping structure made of fused lead glass tubing is described. Reduction of a surface layer of lead oxide in a hydrogen oven is used to form a high resistance metallic layer on the interior of the tubes. This layer is used as a continuous voltage divider for drift field shaping. The EGS shower Monte Carlo code was used to model the performance of the proposed calorimeter. The effects of choice of the tube geometry, gas pressure and sampling scheme (digital vs. conventional) are discussed. The possibility of using this type of radiator/drift field structure in liquid argon is briefly considered.
