Radiation hardness compatibility of vacuum gauge electronics for the HL-LHC era

Abstract The High Luminosity Large Hadron Collider (HL-LHC) upgrade will lead to increased radiation levels in the LHC tunnel. Consequently, hundreds of vacuum gauge conditioning electronics deployed throughout the machine tunnel must be replaced by new radiation tolerant designs. The development of radiation tolerant electronics followed CERN's radiation hardness assurance protocol. Component and system level radiation tests have been performed at different radiation facilities. Issues encountered with an operational amplifier and related mitigation actions are explained. For adequate tracking during production and operation, quality assurance methods were applied. This paper describes the different steps taken to ensure radiation hardness compatibility of vacuum gauge electronics for the HL-LHC era.
