Willem will be away for a week starting on Wednesday of this week. The final topic was a report from Woody of some analysis he has carried out on flashlet data from Ofer and g-2. The connection to the AGS rf is thought to be extraction of beam halo from the bunches remaining in the AGS just after each normal bunch extraction i.e. after each firing of the G10 kicker. Ofer has organized the data by grouping these patterns -detector triggers tightly clustered in time with AGS rf period separation according to which of the 12 extractions initiated the scan. The model that these triggers are to be associated with full bunches still in the AGS predicts that as bunches are removed, no flashlet triggers should come at times associated with the removed bunches.
Some observations follow.
This last bunch is probably the second half of the first bunch injected into AGS from Booster. It is well diluted by the VHF in the front porch. A second observation is that flashlet production per number of remaining AGS bunches increases perhaps significantly for the last few extractions of the twelve.
