Introduction • • • High Luminosity Large Hadron Collider (Hi. Lumi-LHC) Planned upgrade to increase luminosity Important part of the upgrade – new high-field superconducting magnets New magnets New quench detection systems (QDS) to ensure fast and reliable quench detection QDS requires accurate and fast signal measurement using suitable analog-to-digital converter (ADC) ADC has to operate properly in the presence of radiation levels found in the LHC – typical radiation dose of 1 Gy/year is expected To assess ADC behavior when exposed to radiation, an irradiation testing campaign has been conducted 3/9/2021 RADECS 2017 3

Our experience with ADCs ADC SAR Sigma-delta General characteristics • Low power consumption • Simple structure • No latency • Higher power consumption • Large filters and modulator • Larger latency Used so far in QDS • MAX 1162 200 k. Sps 16 -bit • MAX 11049 250 k. Sps 16 -bit • ADu. C 834 100 Sps 16, 24 -bit • ADS 1281 4 k. Sps 24 -bit Performance in radiation • Low rate of SEEs up to 200 Gy • Good tolerance to TID (up breakdown at 400 Gy - 500 Gy to 650 Gy) BUT frequent • Only one type of SEU – single SEEs sample spikes • SEUs in 3 different stages • No SEFIs of the ADC (single, multiple sample, gain/offset errors) • SEFIs in the modulator stage (ADC stops) • Our choice: LTC 2378 -20 1 MSps 20 -bit SAR ADC combines speed with resolution 3/9/2021 RADECS 2017 5
