CIADS is considering to use quarter wave resonators (QWRs), made by niobium thin film sputtered on copper bases, at its low energy section. Comparing with bulk niobium cavities, the Nb/Cu cavities feature a much better thermal and mechanical stability at 4.5 K. A 325 MHz QWR cavity has been fabricated at IMP, to demostrate the niobium coated copper cavity technique can meet the requirements of CIADS. The cavity is coated with biased DC diode sputtering technique. This paper covers resulting film characters, vertical tests with the evolution of the sputtering process, and improvements to mitigate issues we meet.
