== Agenda ==
 * Action items from last meeting.
  * None
 * System updates.
  * Laser driven proton and ion source.
  * Proton and ion capture.
  * Stage 1 beam transport: Beam transport and delivery to the in vitro end station.
  * Stage 2 beam transport: Post-acceleration and beam delivery to the in vivo end station.
  * Biological end stations.
  * Infrastructure and Integration.

  * Version 2 [https://ccap.hep.ph.ic.ac.uk/trac/raw-attachment/wiki/Research/DesignStudy/PreCDR/LhARA-ProjectPlan-v2.xml xml] or [https://ccap.hep.ph.ic.ac.uk/trac/raw-attachment/wiki/Research/DesignStudy/PreCDR/LhARA-ProjectPlan-v2.pdf pdf]
 * [raw-attachment:2020-03-31-LhARA-pre-CDR-review-agenda-d1.pdf Pre-publication review of the pre-CDR.]
 * A.O.B.

== Notes ==
* Participants: AK, HTL, KL, TD, OE, WS, JPas, CW, GA.

 * Status updates
  * laser - OE
   * ZN proof reading but he's on strike.
   * Costings being prepared. 
  * Capture
   * Update in Overleaf.
   * Titus to add detail on diff pumping.
   * CW to work on the R&D part.
  * Beam transport - WS.
   * Focus has been on the write up of v4.3 as the main design and v5.3 as the alternative design.
   * Simulation using a more realistic beam will be done.
   * Ready for feedback.
   * AK to go over this.
   * JPas
    * Looked at tweaking 4.3 to reduced Beta from ~400 to ~50 to facilitate injection.
    * This change moves the focal point for collimation to where the RF cavity is.
    * This would increase the space needed after GL5, for octopoles, cavity and the switching dipole.
   * HTL
    * Updated Overleaf with the transfer line to in vivo.
    * This is more or less complete. Simulations from after RF cavity to the end station as assuming alpha=0 after extraction line.
    * Overleaf has many plots not included in the document. Can decide later what not to include.
    * Inconsistency in the BDSIM simulation being investigated.
    * Beta=58 coming out of extraction translates to 1cm for 15MeV, 3cm for 127MeV assuming 10x emittance growth.
    * AK to look at the write up on Thursday when it'll be ready.
  * GA
   * The costing has been updated based on costs from other existing facilities.
  * Pre-publication review of the pre-CDR - KL
   * Proposed agenda (see attachment) will be circulated.  
   * 20 minutes for each speaker should cover 10 minutes for a  presentation and 10 minutes for questions.
