Counting house status

Hovanes described recent plans and progress concerning outfitting the counting house. Interim networks and phones are in and the UPS installation is being planned along with routing of clean and UPS power. Next in is racks and our network equipment. He is also looking into office area furniture, displays and remote conferencing equipment. At some point we'll have to design and outfit the control room.

Equipment orders

• Mark has ordered some tools, test equipment and rack hardware, but has more to go.
• Hovanes ordered a 5 TB Dell RAID system.
• Hovanes ordered a 6-axis Newport motor controller, likely to be used on a number of beamline components.
• Three VME cpu's arrived, Beni will use them, 8 more on the way.

Solenoid controls

Elliott reported that we are still on schedule for magnet cooldown in Nov-2012. There is a great dealt to do so we cannot waste time. A working control system needs to be designed, purchased, installed and tested by this summer.

• There are no known showstoppers, but we still need the results of the FMEA from George to know the level of redundancy needed.
• The QD is under control.
• It now appears that Yi's National Instruments PXI solution solves the fast/slow daq and isolation problems.
• Scot noted we may have more coil tap signals than expected since George wants taps in more places.
• Scot ordered another Lakeshore temperature monitor. We have no spare channels in the four units.
