= LhARA Radiobiology Meeting: 06Aug26; 14:00 BST = **ZOOM:** https://imperial-ac-uk.zoom.us/j/98220889714?pwd=SM90vOF7BKSXoU3mD9q7OwBQo4IVB3.1 - Planning Document: https://docs.google.com/document/d/1OTARVtxhLRu02S6CLdRDB2QlGvCqDfZ3aWBifjIFs_Q/edit?tab=t.0 - Trello: https://trello.com/invite/b/67587c515b0c69656ee78b48/ATTIe86f94b24e3e5884e4cb87e5ed3b89ab64321B83/poplar == Meeting Notes == 1. BioPrep - Josie: Summary of last week's biology meeting: - Bio plan being prepped short- and long-term, covering both experiments within our existing collaboration remit and ways to expand the team/bring in outside experts. - Jason and Emma have mapped internal biological experiments comparing radiation source results from cells to organoids to animals (see Emma's RAL lecture). - Plan to hold a seminar day with the wider field to showcase LhARA, discuss overlapping work, and identify partners suited to joining LhARA or collaborating. - Further meetings needed to nail down specifics for both the seminar and near-term experiments. 2. Instrumentation - RCF: - Tony investigated delaminated EBT3 as a thinner alternative for dosimetry (minimal dose interference) but couldn't source it. Discussed manufacturing our own instead. - Marie flagged that Alexander Mullen works on polymer thinning/stretching — plan to meet him to discuss making a thin sheet to sit in front of the cells without significantly reducing dose. - Also agreed to reach out to NPL: Richard G. will connect with Giuseppe to discuss their similar process. - Richard also mentioned the benefit in looking at fast electrons and will report back findings at the next meeting. - Scifi: - Unlikely to get clear fibre to Robbie before he goes to ELI and want to test it at Birmingham first - Equipment currently at Queen Mary's (Ken talking to them) - Air Scintillation - Colin/Narendar: Planning to meet to discuss the feasibility of the implementation at SCAPA and the timeframe 3. SCAPA - Team busy- no updates this week 4. Alternate Beamlines - No ELI feedback yet 5.
