Abstract

At the LHC installed electronics will be exposed to a radiation field of mixed particles over a wide range of energies. While Monte Carlo transport codes can be used for calculations and predictions of radiation levels, the complex operation and layout of the LHC accelerator give rise to significant uncertainties. Dedicated radiation monitors are therefore installed in locations of the electronics to provide an on line measurement of the radiation levels. This paper addresses the method that has been applied to calibrate these radiation monitors for their use in mixed radiation fields. New irradiation tests to determine the sensitivity to neutrons from a few MeV to 20 MeV will be presented along with additional irradiation tests with high energy protons.
