**ZOOM:** https://imperial-ac-uk.zoom.us/j/98220889714?pwd=SM90vOF7BKSXoU3mD9q7OwBQo4IVB3.1 

Attended: PH, JMcG, AFr, MH, JPi, CD

== Meeting Notes == 

1. Overview of desired paper and required aims for next SCAPA beamtime
 - Dates: July/August

2. Steps before next beamtime and discussion 
 - Document: https://docs.google.com/document/d/1OTARVtxhLRu02S6CLdRDB2QlGvCqDfZ3aWBifjIFs_Q/edit?usp=sharing
 - Do we have a set beamtime?
 - Cell control tests should be done with irradiated cells as well
  - Can use Marie's lab
 - Mark has a Timepix detector to use as an alpha-particle detector and OSL he will test.
  - If successful, can bring to SCAPA as LET detectors

3. Discussion of aims post-October

4. Aims for ELI
 - Thanks to Emma for coordinating the bid
 - Josie requires more details on the low energy beams at ELI. Currently, can only find information on the 68MeV beams.
  - Calvin to ask Robbie tomorrow.

5. Quick updates
 - In-beam diagnostic
  - PH: Presentation on hollow fibre readout plan
   - [raw-attachment:LhARA_28May26.pdf Slides]
   - Peter has ordered some plastic silicone fibre with hollow core.
   - Zemax simulations show a fibre with a 1.6mm core has 0.14% to ~1m away.
   - Bending must be constant so require tubing and stands to hold the fibres in place 
   - Must consider the 10mm thick glass porthole
   - Need the dimensions of the vacuum chamber to be able to recreate and test at Imperial
 - Bioprep
  - None
 - SCAPA
  - None
