* Simulations
	* MP modelling transmission through PMQs at source at 15 MeV, using quad aperture instead of 2.87 mm radius nozzle.
	* 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.
	* JP presented [raw-attachment:ArcStudyUpdate_10112025.pdf 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.
* AOB
	* IPAC - include poplar? Pose to them if they do a separate contribution or include a 1-page teaser in a broader LhARA contribution.
	* JAIFest - TJK agreed to a remote talk.
