Minutes

"Attending: Elton, Beni, Alexandre, Hovanes, Eugene (Hall D); Todd (CASA); Pavel (RadCon); Curtis (CMU); Richard (UConn).

  1. Announcements
    • Accelerator Schedule: Weekend: beam to dumplet, Monday morning: lock up Hall D/tagger, evening tune beam to dump, Tuesday: CW to tagger dump, Wed morning: insert radiator
  2. ARR3 Recommendations
    • All recommendations complete and request for operation has been sent to Patrizia
    • Final documentation on the completion of items needed for Javier.
    • RadCon will tag the completed shielding in the tagger area with a plaque. The completion will be confirmed to Eugene
    • Fanning has sent a confirmation of all safety items checked during the walkthrough last Thursday
  3. Accelerator and Hall D Interface Document - update
  4. Update on Photon Commissioning (Alexandre)
    • small changes to the plan are being implemented including the last links
    • Tentative proposal to start shifts: standby shifts on Tue evening/night, start regular shifts on Wed day shift
    • Observers in the MCC are welcome during the electron beam tune. Todd suggests that the visits be coordinated with him and Michael. Todd will communicate with Alexandre.
    • Use of the nAmp bpms will start Monday by Trent. Feedback can be useful to him.
    • Discussion of various variable information being made available to accelerator screens. Ion chambers are currently blank on Hall D pages.
    • Alexandre will send the variable names to Pavel. Pavel will also make available a list of RadCon lists that may be useful to Hall D
    • Need to take baseline rates of profile monitor before commissioning starts. Hovanes will do this.
    • Eugene: Need checklists before starting various plans. Alexandre: There are checklists for the electron beam and photon beam separately. We will go over them during the 8:45 meeting tomorrow or Friday.
  5. Beam Simulations
    • Todd: GEANT now up and running on old laptop, but simulations have not started yet
    • Pavel: Getting ready to run the simulations. Could do this by enhancing the neutron production by a factor of 50. If not sufficient to get enough statistics, he may work with Richard to run jobs on the OSG.
  6. RadCon update
    • Note: shielding is being added to the gap in the wall nearest to the dump by Tom's crew
    • RadCon Checklists has a complete list of information that they are responsible for.
    • All monitors are in this list, in particular all in the FSD, but not yet made it into the HCO system
    • Pavel will monitor them and check that they are all operational
    • Checklists
  7. Other business
    1. This is the last meeting in this series. The content will be transferred to other meetings as appropriate.
    2. Beni: Are the goals for accelerator to deliver "quality electron beam" to Hall D defined? Todd: Yes, there are goals to be met and submitted as work plans to ATLIS.
    3. Richard: Preparation for active collimator commissioning.
      • Need to develop software visualization of data to understand the active collimator
      • Hovanes: Trent and Alex have waveforms, as well as FFTs of the waveforms.
      • Yi: Analysis of elements into ROOT for manipulation
      • Data also include integrated waveforms over one second, which may be useful
    4. Alexandre: Can Richard come to JLab for the commissioning of the active collimator? At the moment, it seems this will happen either Thursday or Friday. Richard will investigate schedules.
