Minutes of Oct 10th meeting:
Marco:
New drawings of front flange. Needed input for offset from Mike: offset 88.48mm with 15.37mm clearance to flange material. He also needs length of short beam pipe (presently 3.8", he has zero with a bellows.) Takashi, Al, .. will verify the offset dimension. (e- direct and e- bent is 45.4564 mm) (see Stepan's drawings shown in meeting.) Center of main chamber to center of the 3" hole is 65.75mm.
Marco and Clive will prepare drawing of target (mechanical motion, size and where beam hits, etc.)
Slow control description email.

John:
Vacuum pipe downstream: through 3 magnet to beam dump.
Shielding downstream finalize, ecal. Maurik will have next week.

Meeting with alignment guys at JLAB. Proposal is to align base plate with adjustment bolts, etc. In SVT on Monday afternoon. How to move magnet, survey, etc. Control to 0.5 to 1 mm.

We move the magnet between the parasitic run and the electron run. Marco will have drawing of parasitic run flange downstream.

Slow control systems talk: Hovanes Egyian

Detector cable system. Need rough sketch: racks and chiller. (Side of beam left and upstream can be used.)
