	* Simulations
		* Slides from JP
			* Analytic field map with doublet FF focussing.
			* Able to obtain the initial working point. 
			* Constant tune as a function of KE.
			* Betatron functions.
			* New parameter list.
			* New lattice allows for large variation of vertical tune.
	* CAD
		* Details shown by CH on the layout of stage 1.
			* JP: Distance between len 3 and 4 is critical. Distance between lens 2 and 3 can be adjusted.
		* Further work on the target chamber shown by CH.
		* NB: Progress on FETS FFA engineering details. These details are relevant for LhARA. 
			* CH is looking at the vacuum chamber. 
			* Need to have strengthening ribs and bellows.  
			* This requirement has led to an increase in the magnet gap size.
	* NB: Costing
		* Looking at adding detail to the costing detail used in the PA2 proposal.
		* Discussion.
	* AOB
		* JP: question for CH. What is the size of the wall after lens 2 and is there a shutter? 
			* Nominally 0.5m
			* Is the gap on the current diagram sufficient?
			* Need to do a radiation study. 
			* The size of the wall is important for the injection line.
		* RR: Message from WS re submitting an abstract for the NPL workshop.
			* Consensus is if WS can submit one then that is good.
