* Simulations
	* MP - RL fpr nozzle , small reduction in transmission and divergence
	* TJK - thesis writing. Send fieldmap to JP for dynamic aperture studies.
	* JP - readdress dispersion issue in stage 1 arc. Track large amplitude particle but hard edged model. Investigate need for sextupoles. Beamoptics.
* AOB
	* JP: CDR. Pg 8, five cavities is not correct. Eqn 2.1 units are not correct, should be mass & not energy. Beta0 equation wrong. Gabor lens injector for lens 1 & 2 is downstream, not upstream. Wien filter for velocity selection. Eqn 2.9 should be sigma p, text changed to momentum. Stage 2 operation beam aperture is fine, better reason is emittance issue. Markus ion chamber volume times 10^-8,
