Present: Pavel, Igor, Hovanes, Josh, Eugene, Edy, Beni, Marshall, Vitaly, Sean, Moskov, Richard, Ryan, Sean, Tim

Mikhail was traveling and was not present at the meeting, but he sent Hovanes a message with a very brief status update. Al detectors that KFM needs are uninstalled and prepared for packing (tracker is packed). The moving company wants to pack everything by their own crew to be sure that all pieces are safe. Nothing is shipped yet, since the paperwork is not complete.
Eugene said that in order to bring the KFM detectors here we do not need to have any new documentation. In order to have some kind of insurance, we would need to have at least a loan agreement, or Non-proprietary User Agreement. We do not have to have an MOU to bring in the KFM equipment.

Sean discussed the need for photon beam to calibrate the RF-signal, GlueX detector timing, and GlueX calorimeters.
Sean presented kinematics of photons that would be observed in the final states for the reactions of interest to KLF. His simulations were based on phase space distributions with some t-slope parameters, when needed. Most of the channels seem to produce photons mostly in BCAL with energies going up to 2.5 GeV. The K*p channel produces a lot of photons in FCAL as well , with energies going up to 3.5 GeV.
In Sean's opinion, photon beam would match the kinematics better than neutron or kaon beams.
There is still question of characteristics such a photon beam would need to have to satisfy the calibration needs in a reasonable amount of time.

Pavel reported on his progress with CPS simulations. He has a new model, KLCPS81, which incorporates the magnetic field from the OPERA model corresponding to the official engineering design, new beam displacement monitor in front of the CPS, and modifications to reduce the photon flux on the cryo-target when running without 10% radiator.
