ALICE is a prototype ERL accelerator that is being developed at STFC Daresbury Laboratory, UK. Recently it has successfully demonstrated the energy recovery technique by accelerating an electron beam to more than 30 MeV. A new superconducting LINAC cryomodule is being developed for the operation in CW mode with high average beam current. ALICE will be used as a test bed for this new cryomodule, which will utilise cold helium gas to cool the radiation shield, HOM absorbers and the thermal intercepts for the high power RF input couplers as opposed to liquid nitrogen. The additional cooling power required at 80 K and 5 K will be provided by COOL-IT (a system for cooling to intermediate temperatures). All these modifications would require new instrumentation for diagnostics and control of the additional cryogenic processes, which will be integrated with the existing Linde cryogenic control system for ALICE. In this paper we present an overview of the additional instrumentation requirement with associated integration scheme.
