Please send comments and corrections to Julie.

• 12 GeV preparation
  • [joining now] From Carlos: there will be two PMT shipments back from France : one for high efficiency (16 PMTS?) and another ones for "regular" PMTS. The PMTS will be shipped in January from France.
  • Alex 's trip at Clermont: The installation of CODA has been successful. The end of run routine is crashing the system maybe half of the time ; this is more an annoyance then a big issue. Magali is now working with a "realistic" setting, she has been sending some run to Carlos: some parameters still need to be tweaked (for example, the full ARS window is not showing up).
  • From Charles commenting on shielding design. See entry: https://hallaweb.jlab.org/dvcslog/12+GeV/120 A. Gavalya is proposing two new shielding pieces. One that is stuck along the beamline at the exit of the scattering chamber and another one that is stuck along the calorimeter box on the beamline side. For the first one on the beam pipe itself: still need to decide on its height. For the second one: it might results from mis-communication, it is unclear we need it and it will probably make the motion of the dark box a bit more complicated. [JR missing some discussion here :( ] The people from Orsay will try to see the impact of these shielding with Geant 4.
  • The group have a meeting with Tanja Horn about the neutral facility in Hall C. Fill the Doodle at : http://www.doodle.com/usgvy739c6nc4d6f
• 6 GeV analysis
  • Work being done at Orsay: pion calibration a la Malek, still setting up routines for pi zero subtraction. Geant 4 trying to extract DVCS cross section from the previous experiment: still work in progress.
  • Maxime and the extraction of DIS cross-sections: (1) looking at improving the multitracks corrections. (2) Charles will ping Thia for a new parametrization of the PDF. (3)Found the source of the discrepancy between the simulation and the data (angle theta- vertical): this mismatch only exists when the collimator was in. One issue is that there is no automatic reading for the position of the collimator, Alex will double check this.(4) Deadtime corrections: two different ways to compute them that gives different results. The discrepancy could be due by the amount of beam trip during the run. Maxime is checking this.
• A. Camsonne to submit his DOE early career proposal today at 5pm. Good luck !
