  1. Announcements
    • 12 GeV electron beam has been delivered to the tagger hall, and a photon beam has been extracted as well. This is a great step forward!
      • Nathan shared a logbook entry of the uncorrected PS energy spectrum. There was some discussion of this - the location of the high-energy cutoff is not understood. The measured beam energy reported by the accelerator was also found to be a little slow.
    • Data was taken to study the TAGH voltage settings. There was not much data, and it is not very useful for other calibrations since the RF signal needed was not hooked into the PSC. This has been fixed, and is being verified today.
    • Mark Ito reported that on Friday, he released sim-recon-1.8.0, which is included in version-1.1.1 of the XML version file.
      • The single track and b1pi tests have been updated with all the latest software. The single track is working fine. The b1pi seems to be working, except the jobs running on the same platform as the farm. This needs to be looked into.
      • Mark also reported a rumor that ifarm62 is disappearing, so we will no longer provide builds for CentOS 6.2. Most users have moved on from this platform.
    • Paul reported that the next monitoring launch will be Friday, and will be the last of the year.
  2. Calibration Tasks
  3. Subdetector Reports
    • Naomi reported that some changes she made to the fADC125 emulation code snuck into the main branch from a development branch, and reconstruction of mode 8 data has been broken since early November. Mode 7 data, which includes most of the Spring data being used for calibrations is unaffected. The issues is being tracked on GitHub here. A fix is sitting on David L.'s desk to review, hopefully before the next monitoring launch occurs.
