Here is the latest summary of calibrations, and work left to do.

• Beam Line
  • Calibration database: Not updated!! Find the correct database here: db_beam.dat
    • Note: there are a number of db_beam.dat files in the DB directory, some labeled "rb" for rastered beam, and some labeled "urb" for unrastered beam. Additionally there can be subsets like "db_urb.BPMA.dat" with info specific to BPM-A. Be careful what modules you are loading in your analyzer, and what databases those modules are calling.
    • Note on the Raster: The specific raster database parameters are simply taken from the previous experiment's database.
  • BCM:
    • Status: Completed
    • Personel: David Anez
    • Summary: A BCM calibration was done on March 3rd, 2011. It consisted of four MCC runs, 170 to 173, and three corresponding CODA runs, 2252 to 2254. Summary table can be found on David's web page here.
  • BPM:
    • Status: Completed
    • Personel: David Anez
    • Summary: Bull's eyes scans were taken at run numbers 1579 to 1599. The linear coefficients were extracted and are tabulated on David's web page here.
  • Luminosity:
    • Status: Completed
    • Personel: David Anez
    • Summary: During HAPPEX, special runs luminosity runs were taken at beam currents from 10uA to 80uA to search for possible boiling effects in the target. Seven out of eight Luminosity counters showed a very good linear relationship across all currents. The lone counter with non-linearity is attributed to an oversaturated counter. Again, a more detailed summary can be found here.
