Measurement of Radiation Damage to 130nm Hybrid Pixel Detector Readout Chips
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 xray source was used to incrementally irradiate the separate regions of the detector whilst it was powered. This is the first total ionizing dose study of a large area pixel detector fabricated using the 130nm CMOS technology.
