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!!!
