Announcements

We will no longer cancel Online meetings just because Elliott is out of town. Dave and/or Hovanes will organize the meeting in his absence.

Next Meeting

1:30 PM Wed 30-Mar-2011 CC F326

Minutes

Present: Elliott W, Hovanes E, Simon T, Bryan M, Graham H, Dave A, Eugene C, Chris C, Vardan G, Beni Z, Dave L, Yi Q.

Single board computers

Hovanes ordered 5 Intel-based GE VME single board computers at $3400 each. These are the ones Dave A recommended. Dave noted that the three brands evaluated were all about the same, and GE had the best price at the moment for small quantities. This may change when we purchase large numbers of them. Also, by then the boards will have evolved, as we have seen with the PowerPC boards.

Project management and the JLab DAQ group

Eugene asked us to develop subtasks under the tasks in the 12GeV project schedule and come up with a plan to incorporate JLab DAQ group members into our work plan. Here DAQ group members would charge to the Hall D project, but only for work done explicitely for Hall D. We will use the Mantis system to document and keep track of work we ask DAQ group members to do for us. Further, they could only charge the project for work listed in the Mantis system.

Graham noted that he planned for 10 man-weeks of effort devoted to Hall D in FY11. Eugene asked him to increase this to 20 m-w and he agreed.

Dave L, Hovanes and Elliott will write a short description of each item in the 12GeV schedule, then develop sub-tasks that will guide us and allow Eugene to report on progress to the 12GeV management group. We will use the Mantis system to develop tasks that map the items in the 12GeV schedule to the "boots on the ground" work in the real world (i.e. one Mantis task may contribute to multiple items in the 12GeV schedule, if this is how the work practically gets done).

Coil test

Elliott reported on the recently completed test of coil 4.

• Mechanical installation went well.
• Leak checking was a pain, as usual.
• Cooldown went quite well.
• We were limited in ramp-up speed due to limitations in the protection circuits due to imbalanced coils.
• Magnetic field messed up some trip sensors, experienced many spurious trips.
• Eventually ramped up to 1500 amps with no problems, made measurements for 30 mins, then ramped down.
• Control system worked fine.
• Magnet is now warm and being removed in preparation for coil 3 installation.

Multi-crate test

• Being installed in Electronics lab.
• Most equipment here, still waiting on some boards.
• Tests should be completed in FY11.
• Fiber quotes higher than expected.

UConn tests

• Using CODA 2.6.1 for tagger electronics test.
• Using Labview for active collimator.
• Tests begin in about two weeks.

Controlling CAN devices

• A number of schemes possible, being investigated.
• Many large CAN systems controlled in HENP.

Raw event format

• Dave L says he should have a simulated raw data file by summer.

Event display

• Elliott is reconnecting with Andrew and another student after a long period of no work.

Controls test stand

• Probably will set up in EEL 126 as there is no room in F117.
• Will have a rack, PLC, some modules.
• Will use this to develop controls software for many detector components.
