Description
To enhance heat-transfer efficiency in SRF cavities, we previously introduced a novel approach that coats the cavity with an inner-wall thermal-conducting film (ITCF). Simulation results showed that ITCF absorbs heat from the RF surface and transmits it to cooler neighbouring regions on the inner wall, thereby reducing the heating-point temperature via an extra heat-transfer route. This work presents the set-up of the cryogenic temperature multi-test system in IMP, the preliminary thermal conductivity test for relevant materials that include substrate and film, and the coating properties of ITCF candidates on small samples.
