Multi-batch P-bar production via snap coalescing: A plan to produce {approximately}5{times} more antiprotons/cycle using mostly existing equipment
A method is described to increase the yield of Anti-Protons/cycle by about a factor of five, without building new storage rings. In this method, the full circumference of the Main Injector is filled and accelerated. Existing RF cavities are then used to perform ``snap coalescing`` which clumps the charge in azimuth to produce 28 large RF bunches {approximately}5ns long. These are then extracted and targeted in a single 11{mu}sec turn of the Main Injector. The resulting P-bars are injected into six turns of the Debuncher using a resonant kicker which injects every 21st RF bucket The result is that every 3rd RF bucket in the Debuncher is occupied. After an h=30 rotation in the Debuncher, ESME simulations indicate a final momentum spread of {plus_minus}0.25%. This is comparable to the current momentum spread after debunching. It is superior to the momentum spreads of {plus_minus}1.2% and {plus_minus}2% which would be produced by the Compressor Ring and Linear Debuncher.
