Minutes Went over summary of tasks to be completed for PREX. Comments by Simona and Sasha that Roman should be added to DAQ expert.
Bill continues work on G3 optical transport. It appears that turning Q1 off works fine and we will work on a Q2 and Q4 only optics solution. Working on implementing TOSCA maps. Sasha will provide maps at 1.1 GeV and 2.2 GeV and we will see if they are linearly scalable.
Eric showed results of adding scaled TOSCA map to G4. All tracks mysteriously bent in same direction in quads. Need to understand this. Added phlange prior to dipole and removed a lot of junk from detector hitmaps. Will be in contact with Bill to ensure all G3 geometry and G4 match up.
Update on magnet from Javier. Hi Don,
Last week I was off but before that we had cooled down the magnet and operated it to 4T. Everything went OK. Temps are higher (half a degree at cooling head and magnet, few degrees at power leads) - so, we still have that puzzle. Checked a few things on the target (just repeat of work done by Bill and Ethan previously). The magnet was let to warm up on June 15. No progress has been made on the communications front - we met with the controls group today so, we will we see how things go.
Cheers - Javier
