Testing of the HCC and AMAC functionality and radiation tolerance for the HL-LHC ATLAS ITk strip detector

For the high-luminosity phase of the LHC, which begins operation in 2029, the current ATLAS inner detector will be replaced by a new tracker, the ITk. The ITk consists of two subdetectors, one using pixels and the second using silicon-strips, the ITk Strip detector. The HCC and AMAC chip are radiati...

Description
Summary:For the high-luminosity phase of the LHC, which begins operation in 2029, the current ATLAS inner detector will be replaced by a new tracker, the ITk. The ITk consists of two subdetectors, one using pixels and the second using silicon-strips, the ITk Strip detector. The HCC and AMAC chip are radiation-tolerant ASICs that contribute to the front-end readout, monitoring and control of the ITk Strip subsystem. Low temperature startups and low internal regulated voltage tests have been performed on HCC and AMAC to guarantee their reliability at edge operation conditions. In addition, to ensure the operation of the HCC and AMAC under a radiation heavy environment, gamma and x-ray irradiation campaigns were conducted. HCC and AMAC successfully operated at harsher conditions than the ones expected during the HL-LHC.
