 == Meeting Notes ==

 1.      Optimisation & FEMM results presented in the attached [raw-attachment: LION_12-02_Update.pptx slides]- C.D
+
 - The new optimised tilts/shift positions appear to generate plots that look plausible and seem to recreate the RCF nicely.
+
 2.      Some bugs were identified with the field map quads being placed into the BDSIM simulation:
+
 - Potential issue with the size of the central quad field aperture.
 - FEMM plots present holes in the middle for each RCF.
 - Bugs in parallel scoring simulation result in repeated data points and an energy spectrum with MeV too high.
-More field mapping was carried out in order to try to increase the efficiency in the attached [raw-attachment: Initial_runs_with_PMQ_fieldmaps.pptx slides]- J.M
-- Highlights run-time issues (~6000s per 1000 particles for full field map, ~6000s per 10,000 particles for field map reduced by 90%,) and how we’ve tried to mitigate- reducing eloss scoring, turning on minimum scoring, reducing field size etc.

  == Future Plan == 
+
 Look at the optical response and see if we can reproduce. 
+
 Contact Will about speeding up field maps. Look at bugs.
