Rad-Tol Pt-100 isolation amplifiers for the LHC cryogenic system

Abstract

The cryogenic system of the LHC will use Pt-100 sensors to measure temperatures between 40-300K and isolation devices will be used. The selected commercial components must be rad-tolerant since a total radiation dose of 5E12 n/cm2 &100 Gy is expected during ten years of the LHC lifetime. Neutron tests in this family of devices were performed and the results are shown in this paper.
