Monte Carlo wish list¶

What we have currently:

• Well documented set up to pull in Monte Carlo configuration if it gets
  provided by the engineers
• Well documented set up to configure whatever fields and geometry
  people need
• Poorly documented module to generate multivariate gaussian beams with
  a reasonably flexible parameter set
• Well documented module to track and write out Monte Carlo data
• Poorly documented and possibly buggy tracker digitisation
• Elementary but probably reasonable TOF digitisation - but no user
  documentation

What I think we need in order to perform an end-to-end Monte Carlo of Step IV:

1. Step IV MICE "As-designed" (e.g. legacy/FILES/.../Step4.dat) set up needs to be checked and fixed - are the coil geometries correct? Can we get a reasonable beam through? What are the design absorber settings? Are they the same as what we have in Step4.dat
2. Functioning digitisation for the tracker
3. Trigger digitisation (what form should this take)?
4. KL, EMR, Ckov digitisation
5. Scalars digitisation
6. "As-built geometry" and CDB interface needs to be smoother (operational issue to do with getting geometries into CDB)

What I think we need to improve the "user experience":

1. Quick start guide + examples:
   1. Track a beam through and generate beta function/emittance plots
   2. Track a beam through and generate reconstructed data -> beta function/emittance plot at the Tracker Reference Plane
   3. Anything else?
2. Documentation MAUSUserGuide.pdf should be available to download/htmlarised from the wiki
3. Documentation - some stuff is in doxygen only, it needs to be in the user guide as well.
4. Optics calculation needs to be tidied
5. Python interface for extracting the field values
