== Meeting Notes == 

1. BioPrep
 - New radiobiology specific meeting at 4pm (GMT) Mondays on alternating weeks to this meeting.
 - Let us know if you'd like to be added to the mailing list

2. Instrumentation
 - RCF:
  - Tony update on new film
  - None
 - Scifi:
  - Update on prototype
   - Fibres glued in place, just needs polishing off before testing
  - Need to discuss visit to Birmingham
 - LET
  - Update from Mark:
   - Looking at the data, but looks like there is good agreement with the modelling across the Bragg peak and can get 2D LET distributions.
   - Need to make sure good calibration
   - Potentially take to SCAPA but test at Birmingham first
   - Details about irradiating in the dark to be discussed and figured out.
 - Other detectors (Thin-wall chambers, Diamond etc)
  - Thin-wall chambers have an aperture of 6mm in x.

3. SCAPA
 - General Update
 - Any information on what kind of experiment we will be parasiting off
 - No update


4. Alternate Beamlines
 - ELI proposal:
  - Deadline passed
  - Next deadline most likely March/April

5. Review Trello: https://trello.com/invite/b/67587c515b0c69656ee78b48/ATTIe86f94b24e3e5884e4cb87e5ed3b89ab64321B83/poplar

6. DoNM 
 - 12/11/26

7. AoB 
 - LhARA/CLF Workshop!!!
