Preparation notes for active collimator beam tests to take place in Spring 2007. The online accelerator schedule shows that there will be significant photon running in Hall B in 2007.
- 2-20-2007 [R. Jones] I made an initial contact with Pawel Nadel-Turonski, spokesman of g13. G13 is scheduled for running in Hall B 3/8 - 5/29. Pawel welcomes us to conduct active collimator tests in parasitic mode during this period. The beam endpoint energy will gradually increase throughout this period, starting at 3.30 GeV and ending at the top accelerator energy of 5.16 GeV.

I checked the VME motor drivers in the Hall-B forward carriage but strangely all channels are connected (although I cannot recall more than 2 motors used in the alcove). I'll find out where the cables go next weekend. For sure, I'll have epics controls running for the stage!. I was looking for a table but haven't found Tom Carstens who keeps the stuff somewhere (that's easy to solve!). I connected some cables running from the forward carriage to the Hall-B counting house (in case that we want to look at discriminator signals).
