Abstract
A radio frequency (RF) ion source is utilized at the University of Mas sachusetts Lowell accelerator facility to produce a plasma from which positive ions are extracted and then accelerated. The interior surface of the source becomes contaminated with a dark coating after several hundred hours of usage which reduces the current output of the source. Rutherford backscattering spectroscopy (RES) was employed to analyze the constituents of this coating. Procedures have been carried out to etch chemically this film and to refurbish the ion source.
