h2. Preliminary Agenda
* Effect of Reduced Focus Coil current on MICE Step IV and Step VI attachment:Reduced-FC-Current-Slides.odp attachment:Reduced-FC-Current-Slides.pdf (Rogers)
* Pion contamination in Step I (Domizia/Ole)
* EMR Analysis/Run progress (Ruslan)
* G4beamline Step 1 comparisons (Soler/Bayes/Nugent)
* Tracker Update (Dobbs)
* TOF rate analysis (Durga)
* Gauging the success of Step IV (Blondel/All)
* Multiple scattering & energy loss models (Middleton)
* Dipole Field-Current Discrepancy (Nebrensky)
** Apologies, I'll be setting up the beamline as BLOC.
** Preliminary results still in eLog entry "2413":https://micewww.pp.rl.ac.uk/elog/MICE+Log/2413
*** Note that field in centre of dipole bore (long probe) is maybe 1% less than measured against pole (short probe) so not an explanation for a >5% discrepancy
*** As per VB slide last time, should we be giving dipoles 5 minutes to settle at each setting? Or is 2 mins enough? (tolerable error?) This would need enforcing via Run Control...
** I've dug out and archived on the Grid our "official" field maps for QC quads and dipoles - eLog entry "2433":https://micewww.pp.rl.ac.uk/elog/MICE+Log/2433
* Next time:
** Quadrupole/TOF alignment study (Overton)
** Magnetic measurements (Blackmore/Leonova)
** Date of next meeting: Proposed date is October 31st (NB: Clocks will have gone back in the UK at this point)
