We present the first measurements of the performance of the Medipix3 hybrid pixel readout chip after exposure to significant x-ray flux. Specifically the changes in performance of the mixed mode pixel architecture, the digital periphery, digital to analogue converters and the e-fuse technology were characterised. A high intensity, calibrated x-ray source was used to incrementally irradiate...

There are more than 6000 electronic cards for the instrumentation of the LHC cryogenics, housed in crates and distributed around the 27km tunnel. Cards and crates will be exposed to a complex radiation field during the 10y of LHC operation. COTS and rad-tol ASIC have been selected and individually qualified during the design phase of the cards. The test setup and the acquired data presented in...

The ATLAS Liquid Argon (LAr) calorimeter consists of 182,486 detector cells whose signals need to be read out, digitized and processed, in order to provide signal timing and the energy deposited in each detector element. The current readout electronics is not designed to sustain the ten times higher radiation levels expected at sLHC in the years ≥2017, and will be replaced by new electronics...
