Time-Jitter Reduction on the RF Buncher Signal for the Los Alamos Proton Storage Ring (PSR)

摘要

The multiplier described in this paper is part of a considerably larger system whose function is to generate several synchronizing signals for the PSR. Without examining the details, the larger sync system must, from a basic 201.25-MHz clock rate, generate phase-coherent, low-noise cw signals of 2.795 MHz for the LF buncher, 100.625 MHz for low-precision timing, and 16.77 MHz for the prebuncher in addition to the 503.125-MHz HF buncher described above. In very general terms, implementing these requirements involved dividing the 201.25-MHz clock rate by 72 to obtain 2.795 MHz and multiplying this rate by 6 to obtain 16.77 MHz using techniques very similar to those described in this paper.
