Detectors presently considered for monitoring and
control of the LHC luminosity will sample the
hadronic/electromagnetic showers produced by neutrons
and photons in copper absorbers designed to protect the
superconducting magnets from quenching. At this
location the detectors will have to withstand extreme
radiation levels and their long term operation will have to
be assured without requiring human intervention. For this
application we have successfully tested thick
poly-crystalline-CdTe detectors. The paper summarizes
the results obtained on rise-times, sensitivity and
resistance to neutron irradiation up to a dose of
1015/cm2.
