Agenda and Notes

1. Extended PIT Meeting (Resumption of Operations)

1:00 Goal for Meeting (Ginsburg)

Goal for Meeting


1:10 Experiment Requirements and Desires for next running periods (HALL APLs, Grames)

Posted Fall Running (Grames)

Hall B Run Requirements (Tiefenback)

Document on Hall B Run Requirements (Tiefenback)

Hall C Run Requirements (Benesch)

Comments: Test early at 300 muA will bge tried. A High current (150 muA) 1 pass running. Not too much stress! 30 muA to C is a target max. A could run at lower energy with benefit. High current parity quality. trip interaction with target not bad. Question, stability of the match into hal depends on the gradient distribution. Two hours up to several days to correct. can pre-prepare matches. 10.6 GeV needed to get beyond a physics threshold. 10.5 not good enough. energy in slide. Target faults. Slides from all Halls.

1:25 Performance Expectations in Relocated Modules (Drury)

Expected Performance After CM Swaps (Drury)
