Radiation Tests

  • Report by Steven Passmore on neutron exposure of Endcap boards with DTMROC and ASDBLR99's (1 and 3.5 X 10^14 N/cm^2)

  • Report by Steven Passmore on Gamma exposure of Endcap boards with DTMROC and ASDBLR99's (3MRad exposure at CEA Saclay)

  • Report by Anatoli Romaniouk and Juan Valls on gamma irradiation of an ATLAS endcap wheel sector prototype at the Wieizmann Institute.
    • The prototype was instrumented with 192 channels of prototype electronics. They report on system performance at high rates, looking at occupancy, noise and crosstalk.

    ASDBLR Radiation Studies

  • Histogram of threshold deviations after 10^14 protons/cm^2 exposure
  • Table of changes for 3fc and 30fC Threshold Mean and Sigma Shows that the change in threshold is worse for low thresold, Some of the 1fC max deviation may be due to insturmentation.
