抜粋

The International Large Detector (ILD) is a proposed detector for the International Linear Collider (ILC). It has been designed to achieve an excellent jet energy resolution by using Particle Flow Algorithm (PFA), which relies on the ability to separate nearby particles within a jet. PFA requires the calorimeters with high granularity. A sampling calorimeter with tungsten plates and silicon sensors is proposed for the Electromagnetic Calorimeter (ECAL). Thirty layers of tungsten plates, with total thickness of about 24 X0, are chosen for small Moliere radius to minimize overlap of electromagnetic showers. Fine granularity is achieved by using silicon sensors having 256 pixels of 5.5×5.5 mm2 in an area of 9×9 cm2. The total number of readout channels amounts to the order of 108. We have measured various properties of these prototype sensors: the leakage current, capacitance, and full depletion voltage. To optimize the sensor design, we have also examined relation of the guard ring structure and the cross talk between pixels using an infrared laser system.
