Thick films have bulk like properties. In this paper it is explored the possibility to sputter 70 micron thick films in order to get rid of the Q-slope in Niobium sputtered Copper Cavities. An innovative method based on the multi-layer deposition of zero-stress single layers is re-ported. The deposition of zero-stress thick films into 6 GHz Copper seamless cavities, has shown the possibility to obtain straight curves for the Q-factor versus acceler-ating fields.

Abstract

Thick films have bulk like properties. In this paper it is explored the possibility to sputter 70 micron thick films in order to get rid of the Q-slope in Niobium sputtered Copper Cavities. An innovative method based on the multi-layer deposition of zero-stress single layers is re-ported. The deposition of zero-stress thick films into 6 GHz Copper seamless cavities, has shown the possibility to obtain straight curves for the Q-factor versus acceler-ating fields.
