 We need to provide the “Experimental Interface Group” with numbers for Mu 2

We need to provide the “Experimental Interface Group” with numbers for Mu 2 e running. Basically the maximum instantaneous rate that the experiment can handle. This will go into the decision for the mode of operation for the 8 Ge. V program associated with Project X Ie, whether to include a stretcher/buncher ring as part of the package (Could be accumulator/debuncher or other) E. Prebys –mu 2 e meeting 4/23/08

 If slow extraction can work at all from the Recycler, it certainly can’t

If slow extraction can work at all from the Recycler, it certainly can’t work with more than one “blast” (I’m going to try to make that term stick) at at time. 1 “blast” = 9 m. A*1 ms = 5. 6 e 13 (protons)/(1. 4 s cycle) =4 e 13 p/s on average (!!) = 50 k. W average beam power = 8 e 20/yr (2 e 7 seconds) Compare to baseline proposal 6*4 e 12 protons/(1. 33 s NOv. A cycle) = 1. 8 e 13 p/s on average = 23 k. W average beam power = 3. 6 e 20 Modes of operation considered All “extra” blasts, extracted one at a time 4 in 800 ms = 57% duty factor 1 blast in 200 ms (sharing) = 14% duty factor 1 blast in 800 ms (timeline hog) = 57% duty factor E.
