Abstract
Work on replacing all existing notch filters in the PBAR source with BAW notch filters is described. Three filters have been designed and built for the debuncher, thus eliminating the fiber optic filters. These have been installed since the fall of 1990. New filters for replacing the superconducting filters in the accumulator are now under construction. The delay stability of the BAW device is on the order of 27 p.p.m. per degree centigrade for a sapphire crystal. Maintaining notch frequency spacing requires a constant temperature environment; hence, the entire unit is mounted in an oven.<>
