There is a mapping in the solenoid_map table which specifies a magnetic field setting for a given run number. So we should choose 2 different run numbers and assign these 2 field settings for them so you can generate events which will have different fields. | There is a mapping in the solenoid_map table which specifies a magnetic field setting for a given run number.

Latest revision as of 07:25, 6 January 2017
Agenda [attended: Moskov, Mikhail, Mark, Justin, Volker, Avetik, Kijun, Chan, and Igor]
1) Event generators:
Nick: I have updated the generator with the reactions we talked about at the previous meeting. I will have more time to work on things next week when I will be back at Edinburgh. I will keep you posted with updates.
Franz: I modified the geant3 and geant4 geometry to include the Beryllium target (+shielding). A simple geant3 view is attached [1]. Also I generated and ran 100k K0 p -> pi+ Lambda events but yesterday evening could not figure out why the tracking wasn't efficient (on hdview2 (event display) it looks like many hit patterns should have been reconstructed ... but I think this will be solved shortly).

2) MC News
Mikhail: [2]
Justin: From the meeting today it seems that you would like a new calibration context in CCDB for the klong simulations which seems quite reasonable. I would suggest we collect a list of settings you need specified for your simulation and then we can request these under a new context called "mc_klong". So the two tables I'm aware of that you need modified are
rf_period = 64 beam_period = 64
Simon, what magnetic field did you use in your studies [3]? It might be useful to try something near our nominal field like 1200 A (solenoid_1200A_poisson_20160222) and a lower field setting of maybe 800 A (solenoid_0800A_poisson_20160222).
There is a mapping in the solenoid_map table which specifies a magnetic field setting for a given run number. So we should choose 2 different run numbers and assign these 2 field settings for them so you can generate events which will have different fields.
Simon: I did the simulations at 1300 A.
3) neutron-calculations
Igor: Situation looks tolerable [4].
4) Meson spectroscopy
Volker: Next time
5) CP violation
Moskov: Next time
6) PAC45 is scheduled for a week of July 10, 2017. The deadline for submission of proposals and updates is 8:00 AM EDT on Monday, May 22, 2017 [5].
