h2. 2015/03

* Third draft run plan document is at http://micewww.pp.rl.ac.uk/projects/analysis/documents

* Lots of uncertainty around hardware, so we shall see what happens (ops meeting later)

* FC alignment:-

** Rogers has looked at settings, ~ 50 A solenoid mode looks okay (or 70 A flip mode); still not finalised

** Sophie is back from vacation and will start looking through "reconstruction" i.e. can we get good enough resolutions with TOF cut?

* Q789 switched off for TOF0 alignment

** nb this is a short run but should be done for TOF0 alignment

* SSU switched on with ECE:-

** Uncertainty around the hardware

** VB looking at trim coil currents

** Nb: needs some modelling of iron here - feeding in Jo Langlands (Sheffield grad student) to this effort + field mapping

* Straight tracks

** Staring at MuScat paper, looks like they were systematics dominated (errors ~ 50k muons)

** Working on the statistics analysis (can we get 50 k muons within momentum cut and radial cut at the absorber? what should the cuts be?)

h2. 3/4 December Review

* Step IV

** asked Ao to push through a new round of optics studies - he was distracted by PASI last week

** will then need to process at least one setting with full reconstruction

* Demonstration of ionisation cooling

** Baseline and baseline w/o M1 is at a reasonable point, using RMS emittance analysis

** CR is looking at generic phase space volume analyses (not RMS emittance); to fight the "do nothing" crowd

** Jaroslaw is looking at using third FC as a matching element (no news yet, Rogers pestering)

h2. January optics Review

* v1 agenda handed to KL, v2 attached (some familiar names)

* await revised ToR - but we need to start the writing up process now to have a hope to converge by January; agenda becomes the latex skeleton

* I am scared by the timescale

h2. Step IV

* Precision measurement of emittance

** VB working through the "TOF tracks" analysis (maybe she is in the meeting?), turning it into a reconstruction routine

** Awaits tracker reconstruction/geometry fixes

* Tracker alignment

** Discussion with Melissa/Jason/Durga/Tony Millington

** John Palin et al aligned trackers to monuments on the end face of SSU/SSD

** Tony Millington et al surveyed monuments on the outer rim of SSU/SSD

** end-face monuments are now obscured

** Jason Tarrant is in contact with John Palin to recover any (raw) survey data he may have, hand off to Tony

** Tony Millington will make a remedial survey of SSU on Wednesday this week when the diffuser goes in

** remedial survey on SSD may not be possible due to interference from cables and pipes

h2. Cooling demo

* No update on the paper, chasing on Jaroslaw "cooling demo with focus coil" optics

* No update on the tolerances study, will chase Alan
