Description
Future particle accelerators require performance figures which push the boundaries of what is achievable with current SRF technologies. In this light, research has been completed into the creation of HiPIMS Nb thin films deposited onto copper as a means of achieving these performance figures.
The results from the parametrical investigation into HiPIMS Nb thin films deposited onto copper substrates is presented. The copper substrates were prepared using an electropolishing process. The HiPIMS Nb films were prepared in a large scale commercial coating system by adjusting a number of deposition parameters.
As part of the optimisation process, the films have been characterised using various characterisation methods, including surface, crystallographic and superconducting analysis, to determine the effects of the deposition parameters during the film growth process. The effects of the HiPIMS duty cycle were also elucidated from the results.
