Description
During operation at instantaneous luminosities of up to 2 10^34/cm^2/s the
frontend chips of the ATLAS innermost pixel layer (IBL) experienced single
event upsets affecting its global registers as well as the settings for
the individual pixels, causing, amongst other things loss of occupancy,
noisy pixels, and silent pixels. A quantitative analysis of the single event
upsets as well as the operational issues and mitigation techniques will
be presented.
