|MOPP033||Preliminary Design of Mu2E Spill Regulation System (SRS)||176|
Funding: This work was supported by the U.S. Department of Energy under contract No. DE-AC02-07CH11359.
Direct µ->e conversion requires resonant extraction of a stream of pulsed beam, comprised of short micro-bunches (pulses) from the Delivery ring (DR) to the Mu2e target. Experimental needs and radiation protection apply strict requirements on the beam quality control and regulation of the spill. The objective of the Spill Regulation System (SRS) is to maintain the intensity uniformity of a stream of ~25K pulses as 1012 protons are extracted at 590.08kHz over a 43msec spill period. To meet the specified performance, two regulation elements will be driven simultaneously: a family of three zero-harmonic quadrupoles (tune ramp quads) and a RF Knock-Out (RFKO) system. The SRS will use two separate control loops to control each regulation element simultaneously. It will be critical to coordinate the SRS’ processes within the machine cycle and within each spill interval. The SRS has been designed to have a total Gain-Bandwidth product of 10KHz, which can be used to mitigate several sources of ripple in the spill profile.
