14	14	* MP modelling transmission through PMQs at source at 15 MeV, using quad aperture instead of 2.87 mm radius nozzle.
15	15	* KL showed slides on SCAPA results, star-like pattern originating from PMQ fields. Looking to model, questioned which code. TJK recommended OPERA or FEMM, CW recommended CST. WS recommended Stephen Brooks code as a baseline for OPERA/FEMM/CST comparisons in the good field region.
16		* JP ~~showed slides~~ with results matching MP's results. Discussion on need for sextupoles in the arc. Question on the biology end station specifications, CW says 10% is being used at SCAPA, metric is different to ours, particularly considering 1D projection.
