   2 // __Development of next steps in LhARA accelerator R&D programme:__// C. Whyte, J. Pasternak \\
    - CW: Work is progressing on the Gabor lens paper and in the preparation of a plan for the next steps in the development.  Collaboration has been established with the University of Swansea.  Next meeting will be aimed at defining the way forward.  Discussions with the LhARA proponents within the CI have been initiated.  STFC call for funding for engagement/impact IAA at Strathclyde will be considered as a source of funds.  Need for longer-term funding noted.
+   - JPa: Design of FFA ring continues.  Presently assumes a single spiral element as this is the cheepest and simplest solution.  Want variable-energy extraction and zero chromaticity.  This requires particular magnet properties and complicated windings to ensure that beam tuning can be done.  Attempt to use rectangular magnet is now being made.  The price to pay is more rapid acceleration, or the use of a doublet lattice.  The horizontal and vertical tunes can be adjusted using two magnets rather than a single one.  Can keep working point and stability at injection.  Zero-chromaticity requirement still being worked on. \\
+   - TG asked about possibility of using magnetic induction acceleration.  JPa replied that this had not yet been considered -- medical application is to push beam into extraction septum.  TG offered to review possibility; JPa agreed.
   3 // __Proton- and ion-acoustic imaging:__ J. Bamber, P. Beard \\
    - J.McGarrigle has made progress determining the power spectrum of a proton beam in a water phantom.  Next step is to share power spectrum with B.Cox (UCL) to begin study of acoustic signal.
