First Results with Prototype Detectors of the Si/W ECAL.

摘要

Measurements on the prototype silicon sensors for use with an electromagnetic calorimeter with tungsten absorber are reported. The prototype sensors are based on a hexagonal geometry that optimally utilizes the space available on 6 inch silicon wafers. The sensors are segmented into approximately 750 5mm hexagonal pixels, which are connected to a bump-bonding array located at the center of the sensors. We report on those properties of the sensors that are important for linear collider applications including depletion voltage, stray capacitance and series resistance.
