e10001: Tasks:

  1. Resurrect HiRA test setup (Juan, Jake, Zbigniew)
    • mechanical work and cabling is basically finished
    • vacuum test done
    • what is left:
      • test the electronics with the scope
      • test the old readout
  2. Development of the NSCL DAQ software for upcoming experiments with HiRA - work order: RC100609.11720.W01576 (Ron Fox)
    • previous task has to be finished first
  3. Upgrade the HiRA readout to ringbuffer (Juan, Zbigniew)
    • previous 2 tasks have to be finished first
  4. New 2-gain boards (Jake, Bill, Zbigniew)
  5. New CsI cables (Jake, Bill, Zbigniew, Mike)
  6. Assemble 3 new HiRA telescopes (Juan)
    • need drawings of the board
    • need part numbers
    • how many CsI crystals do we have?
  1. Modification of the drawings of HiRA PA box for an upcoming experiment - work order: RC100609.11720.W01613

To-do list based on the meeting on Tue (12/27)

  1. Where can the Caesar stand be made?
    • We should wait for the response from Jim Wagner but there is a high probability that the CAESAR stand cannot be made on time at NSCL. We may have to find another shop that can do it to keep the experiment on the schedule.
  2. HiRA
    1. HiRA Si cables
      • we need 2×14 cables
      • who should make those cables and should they be shielded?
      • we could reuse HiRA dE cables (that should be long enough) but we have only 20 so we should make more. Those cables are schielded. PLEASE ANSWER
    2. New CsI cables. - NSCL is going to make them
    3. How many detectors are you going to run with 2-gain setup? PLEASE ANSWER
    4. New 2-gain boards - WashU is going to make new boards. Did they test them? PLEASE ANSWER
    5. preamps; WashU brings own preamps and figures out how to cable them and put the setup together. PLEASE CONFIRM
    6. Can we run 12 CBs in one MB? NSCL is going to test it. The Sparky should be able to handle 12 CBs w/o si detectors but the issue is whether it can handle the setup of 12 CBs connected to the si detectors. In the past we could run up to 11-12 CBs in the MB with Jon's power supply but we couldn't run more than 9 CBs when the si detectors were connected.
    7. Related to 2.f. If we need to use 4 MBs then WashU should make new flange.
    8. Put HiRA racks back to old configuration. - NSCL responsibility
    9. Request VME/USB for Epool.
      • The issue is that there is no single vm-usb module in NSCL epool. Ron has one that he uses for software development and Dirk has one that belongs to gamma group. It's possible that WashU will have to bring their VM-USB module to NSCL to run the experiment. PLEASE, LET US KNOW IF YOU CAN'T BRING YOUR MODULE
    10. How are we going to run HiRA Si (in terms of VME modules)?
      • How many modules and what type are going to be brought by WashU (XLM with 2 lvds? XLM with 1lvds and 4fadc?)
      • How many XLM modules do you need from NSCL? We have to make sure we have backup modules.
      • We don't have a single XLM (1lvds, 4adc) at NSCL. Can Ron develop his code without this module? PLEASE, RESPOND
    11. HiRA test setup available for Ron - Should be ready this week - NSCL responsibility
    12. Check that we have working Pico systems. - NSCL
    13. Confirm that we have straight pulser through to Csi PA’s - NSCL
    14. Are we going to use CSI discriminator in PICO? PLEASE CONFIRM
    15. Remove dE silicon detectors?
      • PLEASE, MAKE A CASE WHY WE SHOULD DO IT. Aren't we going to have calibration beam?
      • NSCL is going to revisit the procedures of removing and mounting the dE detectors.
  3. CAESAR
    1. Use part of existing setup, but use VME qdc’s
      • we have enough QDC modules
    2. Setting up and testing - 100% WashU responsibility. PLEASE CONFIRM
    3. Our previous experience with VME QDCs shows that it helps to AC couple. Jack is going to send you the description of the setup we used previously so you can decide if you want to use it.
      • We should have enough boards to do AC coupling - JACK
      • we can send the bastard cable setup to WashU - JACK
    4. Are CAESAR cables long enough so they can reach VME QDCs? Do we need the cable extensions?
      • Have to decide on the location of CAESAR and HiRA racks - WashU responsibility PLEASE CONFIRM
  4. Beam blocker drawings
    1. Zibi talked to Craig on Tuesday. It seems like there is enough room to retract the blocker from the beam so it doesn't shadow the HiRA. We should be also able to rotate the beam blocker- the source is going to be mounted on the side of the beam blocker. Craig took the measurements of the alpha source to fit it in his drawings. We should get the drawings soon.
