h2. Actions

* ACTION  *(Pasternak/Rogers)*: determine magnetic settings routine - do we imagine "equivalent coil"? Implement iron in MAUS(!)? Run everything through OPERA?

* ACTION *(Rogers)*: Tolerances - controls people ask what are the tolerances on magnet current

h2. RLSR/MPB Actions

* ACTION *Rogers*: Review the requirements for accurate end-to-end simulation

* ACTION *Rogers*: Report, in a MICE note to the collaboration, the definitions and methods used for the determination of the betatron functions and emittances.

* ACTION *Rogers*: Carry out an independent review of the beam dynamics analysis

* ACTION *Rogers*: Define strategies to provide online feedback, quickly

h2. Actions following Run planning meeting

* ACTION *(Nugent)*: Estimate data rate with cooling channel magnets off

** Still waiting on good April data - this weekend?

h3. Field Off Trigger Rate

* Solenoid fields off triggers at TOF1 44000 TOF2 1000 

* Solenoid fields on triggers at TOF1 53000 TOF2 43000

** => 3 % rate scaling; but run with TOF2 trigger; so limit comes from ISIS/target

* 120 triggers per spill with the Decay Solenoid at TOF1, not including tracker deadtime

* Jaroslaw notes attempt to optimise was not successful

h3. Physics shifter

* Seek to get the physics devil automated

h3. Beamline

* Validated calibration

* Checked some old settings

* Made two additional settings to match to diffuser

* Made two additional settings to optimise for "straight tracks"

* Seeking to validate MC

h3. EMR Papers

* Review next week (Tuesday)

h3. Pion contamination

* See slides

* Feldman-Cousins?

** Frequentist method based on likelihood ratio; can deal in an automatic way with statistical results that fall outside of physically allowed; determines upper limit or two sided; 

** Paul Soler suggests alternatively use Bayesian method (e.g. Higgs papers)

h3. MDIC

* Final coil positions by MAP meeting

* Use IPAC paper as starting point for PR-ST AB paper

h3. Error Fields

* Slide 4: cusps come from the mesh

* Slide 4: symmetry point is at -2.75; tracker is at around -4.75 to -5.75

* Few * 10^-4 T in the tracker azimuthal

* Slide 9: units are T at 0.15 m

Solenoid fields in 2 weeks time

h3. Non-linear beam optics

* Looking at the 6x6 problem...
