Testing of the HCC and AMAC functionality and radiation tolerance for the HL-LHC ATLAS ITk Strip Detector

The ITk Strip is a new silicon-strip charged-particle detector for the HL-LHC ATLAS experiment. The HCC and AMAC chip are radiation-tolerant ASICs that contribute to the front-end readout, monitoring and control of the ITk Strip. Comprehensive functionality tests have been performed on HCC and AMAC to guarantee their reliability throughout the HL-LHC lifetime. In addition, to ensure the operation of the HCC and AMAC under a radiation heavy environment, gamma, heavy ions, proton and x-ray irradiation campaigns were conducted. HCC and AMAC successfully operated at extreme conditions and were reliable at the expected HL-LHC conditions.
