Title: Preliminary Design of Mu2E Spill Regulation System (SRS)

Conference ·
OSTI ID:1614726

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 re-quirements 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 1e12 protons are extracted at 590.08 kHz over a 43 ms spill period. To meet the specified perfor-mance, two regulation elements will be driven simultane-ously: 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 co-ordinate 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 10 kHz, which can be used to mitigate several sources of ripple in the spill pro-file.
