= LhARA radiobiology; meeting: 23Oct25; 14:00 BST = **ZOOM:** https://imperial-ac-uk.zoom.us/j/98220889714?pwd=SM90vOF7BKSXoU3mD9q7OwBQo4IVB3.1 Attended: CD, EM, AFr, KL, JMcG, CW, TP == Meeting Notes == 1. Minutes and actions: - **RW**: Fine-tune installation of cell carousel - **Stands** - **RW:** Send proton numbers to Tony to get the dose rate - **Done** - **CD/DA/Afr:** Find final beam setup with gold foil - **Stands** - **CD:** Find alternative 8MeV setup - **Done** - **EM/JMcG/DA/more visitors:** Complete the online training indicated by Mark - **Stands** - **CW/RW:** Turn on and clean the water in the incubators - **Stands** - **CW:** Contact Marie Boyd - **Done** Waiting - **RW:** Add lip to RCF holder - **Stands** 2. Strathclyde: BT, ED, RW \\ - Dose rate updates - Tony and Calvin to meet with Robbie to sort this out. Invite Nick Dover as well - Fine-tune carousel - Incubator not turned on yet - Colin offered to sort it; just needs access 3. Simulation CD, DA, AFr: \\ - Results of 8MeV setup - 8MeV requires smaller drifts, but there are some values that fall into an acceptable range. - [raw-attachment:10MeV_vs_8MeV.pptx Slides] - Priority is to achieve a high dose, uniformly across the dish. Uniformity needs to be no more than 10%. Also must be uniform across the depth of the dish too, so no Bragg peaks, which means no protons entering the media with less than 1MeV. - Set up optimisation to find the best setup to achieve this. 4. BioPrep EM, JP: \\ - Finalised irradiation plan - [raw-attachment:Glasgow_Cell_Plan.docx Plan] - Confirmation of plan for staining cells - when and who is needed - Need to have someone available on the 14th to do staining from the 5th. - Contact Diaza about whether he will be available - Contact Robbie about clearing people for weekend work in case clonogenics are done on the Thursday or Friday - For the clonogenic cells in the third week Emma will stain these and then bring them back to Birmingham - Cannot be done on the 28th so clonogenics on the third week should be aimed for Tuesday, the 18th Nov - Marie Boyd has been contacted but no response 5. Beam Diagnostics KL, CD: \\ - RCF update - Trying to get as much done as possible at Imperial with Kevin - Lip on RCF holder - No update - Real-time beam diagnostic - Lanex cannot be placed around the cell dish as previously hoped. No room to fit the camera in. 6. DoNM - Next Week: 30th Oct 7. AoB - Confirm everyone has filled out the sheet and confirmed they are visiting - Link to the sheet: https://docs.google.com/spreadsheets/d/13vkixxNBZX42WFtxw7_MFJTU-gc06J19N8zpTcMKFys/edit?usp=sharing - Ken to determine visiting dates - Emma to fill out sheet but has completed training - Visitors complete the online training indicated by Mark ---- === Summary of actions === - **CD/DA/Afr:** Find final beam setup with gold foil - **Visitors:** Complete the online training indicated by Mark - **CW/RW:** Turn on and clean the water in the incubators - **RW:** Add lip to RCF holder - **RW/TP/CD:** Meet to discuss dose rate calculation. Tony to send an email for the meeting time. - **DA:** Confirm availability for staining - **CD:** Confirm possibility of completing staining at the weekend - **CD:** Fine-tune run plan for first week and fill out details from irradiation plan - **KL/CD:** Get RCF cut
