1. 10 Aug 2010PC 423 1 Analysis PC Schedule Tuesdays fortnightly Provisional dates 10 Aug 24 Aug 7 Sept 21 Sept But it’s holiday season so they may vary – people, including myself, will be away Let me & Yagmur know of any items you wish to present

2. 10 Aug 2010PC 423 2 Agenda Schedule &c - JC + Questions / issues from last meeting & VC TOF Calibration - Yordan K. Cerenkov Calibration - ??? Beam Characterisation - Mark R MICE tuning - T. Carlisle IRIS Diffuser - V. Blackmore Wedge absorbers - P. Snopok / C. Rogers (in light of expense of LiH) ??? FC magnetic measurements - C. Tunnell Step III / IV comparison - Tim Carlisle +... [This lives again, stimulated by Ken Long.] Beamline in G4MICE - C. Rogers Statistical Errors - JC AOB-1 AOB-2 Apologies from VB, TC & probably others David Forrest would like to advertise the Database Workshop on 17 August(?) Yagmur suggests “Data Challenge”

3. 10 Aug 2010PC 423 3 Questions & issues from last time and last VC Congratulations to everyone who has worked on the analysis 1) X  -X ambiguity in in TOF1 ?? 2) TOF calibration: Drift? e+ / e- differences? (maybe Mark will address these) 3) More direct comparison of data / G4beamline as proposed by J-S G: Looking at X-X’ plots is indirect Straight comparison data / G4BL X0, Y0, X1, Y1 distributions more direct but also the (6) 2D distributions of X0 – Y0, X0 – X1 &c because X0 – X1 etc. used to derive X0’ and X1’ via Xfer matrices 4) Statistical errors – have been worked out & circulated to a interested parties

4. 10 Aug 2010PC 423 4 From David Forrest I would like to make a shameless plug at the analysis meeting for the database workshop on the 17th its for people who wanna know how to use it, how to add functionality if they want to do something new, how to fix it if it breaks (the easiest 'expert on call' job around) There will be talks in the morning and afternoon hands on sessions. Places are limited (I'm not even sure if there will be room for me) but podcasts and slides will be available of all the talky bits. I will either attend personally if I can find a working phone or upload a slide for AOB

5. 10 Aug 2010PC 423 5 From Yagmur... Now that we have real data from Step I and a good effort toward understanding it, we should know soon what the actual beam coming down the pipe looks like. Given that information, we should use the shutdown period to mount another data challenge and generate "enough" (tbd) monte carlo events with the appropriate bells and whistles (trigger simulation and beamline geometry in G4MICE, etc.) for carrying out a focused study of the future stages of MICE with everyone working off the same (simulated) data set. This is not a small project (have to define requirements, set goals, put new features in the software, make releases, define input configurations with potentially incomplete geometry information, run jobs on the GRID, make the data available, etc.) but worth the effort....may be able to get more people working on MICE analysis if there's a well-defined path with a standard data set and analysis tools. JC comments: – Would need to know what questions to ask / answer - Step III/IV comparison will take place –
