Irradiation Testing of HGCROC3: the Front-End Readout ASIC for the CMS High Granularity Calorimeter

Résumé

The HGCROC3 is the final version of the front-end ASIC designed to readout the 6 million channels of the future HGCAL detector. Along with cutting-edge specifications in terms of low noise, time measurement precision, and ability to contribute to the Level-1 trigger decision, one of the key requirements for the HGCROC3 is a high radiation tolerance.Several irradiation campaigns have been carried out on HGCROC3 prototypes, with particular emphasis on the Total Integrated Dose (TID) and the Single-Event Effect (SEE) tests. In the context of the TID campaign, results are presented in terms of power consumption, charge and time measurement performance, clocks, and serial links robustness. Although previous versions of the same ASIC architecture show encouraging results in terms of SEE hardness, in this final version of the chip a special care is taken to reach the radiation tolerance requirement for critical blocks such as the digital counters, the clocks and the serializers. The corresponding studies of SEE effects on these components are also reported in this contribution.
