Radiation hardness test of the nSYNC ASIC with 60 MeV proton beam

Abstract

The nSYNC chip is a radiation tolerant custom ASIC, developed in UMC 130 nm technology for the upgrade of the readout electronics of the LHCb Muon System. The chip will work, over ten years of upgrade operation, in a radioactive environment and exposed to a total dose of 13 krad and a fluence of 2 · 1012 cm 2 1-MeV neutrons equivalent. The results of radiation tests performed at the Catana facility (INFN Laboratori Nazionali del Sud) with 60 MeV proton beam are discussed, with a particular focus on the internal logic and TDC performance, and Single Event Effects measurements.
