Hardware Agenda

  1. Announcements
  2. CDC Update
  3. FDC Update
  4. Calibration Discussion (File:20131009 cdc calib.pdf)
    • Current "calibrations" in use in reconstruction:
      • Function for CDC time-to-distance relationship
      • Function for correction for deflection due to Lorentz force in FDC
      • Charge-to-energy unit conversion for FDC cathode strips and CDC wires
    • Current "geometry" adjustments possible??
      • Inter alignment between CDC and FDC
      • Absolute locations of CDC and FDC
      • Adjustments to wire locations
      • Possible rotations.

Minutes

Present: Curtis, Naomi, Beni, Eugene, Fernando, Tim, Lubomir, Simon, David L, Sean

  1. CDC Update
    1. We reviewed the travel plans. CDC_travel_plans. We are planning to deliver the CDC on Oct 29, or a day later if the weather is bad, either to the EEL building or to Hall D, depending on the time of arrival. Tim will make arrangements with shipping & receiving & security, and liaise with Gary re delivery.
    2. The CDC cart is 80" long x 53" wide.
    3. Beni can reuse the FDC's test stand for the CDC after the FDC has moved into Hall D. There are enough readout electronics and scintillators at JLab but Beni will need to make something to support a scintillator above the CDC.
    4. Beni will make a TOSP. (?)
    5. Naomi will send Beni her CODA readout files and trigger timing.
    6. Naomi will keep one flash, Beni's crate and one non-production cable for use at CMU with the prototype for readout testing.
    7. The CDC cooling should be installed before the electronics; in EEL the rings can be used with compressed air, in Hall D Tim will try using ducted air with a compressor as a last resort.
