     56 * Action items
     57  * JPar to look at spot scanning.
     58   * Trying to arrange a date to meet Karen. Could be Feb.
     59   * Spot scanning may not be necessary, can do many things with passive scattered.
     60   * KL: Energy too low to passively scatter.
     61   * KL: For microbeams:
     62    * Ideally like to get back to laser target spot size. ~70 micron.
     63    * Other people do few hundred microns width beams.
     64   * Discussion re fixing spot size for spot scanning.
     65    * Choose 100 micron spot size for scanning.
     66 * System updates
     67  * Capture.
     68   * Summary of discussion on 20th Dec.
     69   * Calculations from Colin on differential pumping.
     70    * Prelim calculations show can have 2 orders of magnitude pressure differential.
     71    * Need to include investigating this experimentally into the R&D plan.
     72   * CW spoke to Bob Bingham who is interested in the lens.
     73  * Beam transport
     74   * BDSIM model updated to include all features. Most of Stage 2 parts are there only as placeholders, waiting for physics design to be finalised.
     75   * Looked at countering space charge by neutralising more at the start to improve transmission.
     76   * Include phase rotation/bunch compression RF cavities.
     77    * JPas: I can provide bunch length at extraction and energy spread.
     78    * JPoz: I can then work out voltages and drifts.
     79  * End stations
     80   * Going over floor plan.
     81    * Second end station will be incorporated.
     82    * WS to send JPar snapshot of beamline.
     83    * Meeting with Birmingham re FLASH irradiations. They will set up a FLASH R&D facility and hope to start irradiations end of Jan to early Feb.
     84    * AK: Have they done anything on dosimetry.
     85     * Not yet.
     86    * KL: Tim Greenshaw is giving a seminar in Birmingham.
     87 * AOB
     88  * Schedule and costing from KL.
     89   * KL to circulate the project and request WPMs to update their parts.
     90  * JPas: deadline for APAC on 9th.
     91  * IOP HEPP and PAB meetings, need to submit abstract by 24th Jan.
