Semi-Digital hadronic calorimeter for future high energy physics experiments
Résumé
A new concept of high granularity hadronic calorimeter based on a semi-digital readout for future ILC experiments is presented. The aim of this concept is to provide the HCAL with a tracking capacity in addition to a good energy measurement resolution. The sensitive medium of this HCAL is made of very thin gas detectors. The readout is based on detector-embedded electronic boards equipped with low consumption daisy-chained 64-channel chips. The nice results obtained with a slice test made of small detectors show that the concept is successful and can be used to build a 1m3 semi-digital HCAL prototype.
