Abstract :
A titanium nitride (TiN) coating can reduce multipactoring problems in vacuum cavities and also reduce photoemission electrons from beam-pipe surfaces. A new technique is being explored at LBNL that will allow an efficient way to coat differently-shaped surfaces with TiN. In this technique, an RF-induction discharge with an exposed Ti induction antenna is employed. Tests are being performed using Ar, N, and a mixture of Ar-N gases. It is found that the characteristics of the TiN coating depends on the processing time and the gas that forms the discharge plasma
