Radiation Testing of an SAR ADC for Use in Quench Detection Systems for the HiLumi LHC

Abstract

This work presents a radiation assessment of a successive-approximation-register (SAR) analog-to-digital converter (ADC) for purposes of a new generation of quench detection systems (QDS) that will be used in the radiation environment of High-Luminosity Large Hadron Collider (HLLHC). The assessment has been performed by conducting an irradiation testing campaign using a proton beam with radiation doses up to 1 kGy. The test results render the selected ADC highly robust for use in future applications of quench protection in the LHC superconducting magnet circuits.
