Abstract :
A new type of high resolution beam position monitor called the damped slot resonator RF BPM has been installed at the focal point of the FFTB. It is comprised of a cylindrical resonant cavity with a tuned choke joint at the TM110 resonance. The BPM has a large dynamic range from the nm to mm range with a minimum resolution of 1 nm. We report on the RF cavity cold tests performance, processing electronics design, and some experimental results obtained in the high energy electron beam line
