IPM and FW Update 3/4/2009
Mulitbatch Partial or Missing Profile • Tuesday Feb 10 -the 2nd bunch was being injected while the wire was flying. This would often show up as the first pass of data being taken prior to the 2nd bunch being injected. We delayed the start of the fly by .05 seconds. The 2nd bunch now shows up consistently on the horizontal wire data.
Second Bunch Not Yet Injected Wire Speed and IBeam
Integrator Mods Tue Mar 3 14:09:21- The Main Injector Flying Wire Integrator hold time was decreased to 100ns from 200ns on the Horizontal and Vertical Proton Integrators today. This should help reset the integrator more completely between the 2 batches on multi-batch proton injection. 6862_09030412:48:18_0 6855_09030307:10:36_0 6855_090303_07:10:36_1 6862_09030412:48:18_1
