Abstract

A novel TM020 demountable test cavity has been fabricated by the Spallation Neutron Source (SNS) from large grain niobium ingot sheets. This TM020 cavity is designed to have a demountable test plate at the base of the cavity to allow for measuring RF properties as well as performing surface science analysis in an aim to develop plasma processing as a cleaning method for niobium cavities. Large grain ingot sheet fabrication methods were chosen to reduce the cost of the cavity and to produce smooth surfaces at high electric field locations with standard chemistry techniques, i.e. buffered chemical polish.
