| | 10 | 2. //Strathclyde Updates: // RG, RW, CW \\ |
| | 11 | - Laser damage and beamtime: |
| | 12 | - No major update. |
| | 13 | - Still on for July run. |
| | 14 | - Characterising the source to begin ~the week of the 14Jul |
| | 15 | - Quad alignment and set up to be from 22Jul - 25Jul (21Jul is a bank holiday) |
| | 16 | - Include cell sample for this run. |
| | 17 | - Funding can extend until end of the financial year. |
| | 18 | - Need to change the times of no-cost extensions (Emma to chase Tony about this). |
| | 19 | - Bio phase to occur after September |
| | 20 | |
| | 21 | - Bio-safety cabinets |
| | 22 | - Fixed! |
| | 23 | - Recalibration to be completed in the next week |
| | 24 | |
| | 25 | - Waste and plastic consumables: |
| | 26 | - Plan confirmed to use the autoclave in the Wolfson building. |
| | 27 | - Need to train someone to carry the waste over. |
| | 28 | - Marie Boyd is the back up. |
| | 29 | - No update from Jason as off, but had been contacted by Marie. |
| | 30 | - RCF stack fiduciary: |
| | 31 | - Larger stack cut and notched |
| | 32 | - Smaller stack more tricky. |
| | 33 | - Can send to Rutherford for laser cutting |
| | 34 | |
| | 35 | 3. //Field mapping, preparation of PMQs: // HO/BS \\ |
| | 36 | - Everything delivered or on delivery to Strathclyde. |
| | 37 | - Expected by Monday (30Jun) |
| | 38 | - Marked with a sharpie to indicate which way is forward. |
| | 39 | - F quad has the lettering the right way around when placed correctly in beamline. |
| | 40 | |
| | 41 | |
| | 42 | 4. // PMQ Positioning/Beam optimisation: // CD, RG, JMcG \\ |
| | 43 | - Tony produced simulations with an average of 5.6KeV/um |
| | 44 | - Previous simulations of 10MeV had shown an average of 4.8KeV/um |
| | 45 | - Waiting for overlay from Tony to better understand distribution of LET |
| | 46 | |
| | 47 | |
| | 48 | 5. //Simulation update: // KL, CD \\ |
| | 49 | - G4 simulation of RCF stacks complete. |
| | 50 | - Verified with SRIM and in comparison with LLO. |
| | 51 | - Does not show the splitting effect that was hoped for |
| | 52 | - Further verification with TOPAS simulating an RCF stacks |
| | 53 | |
| | 54 | 6. //Bioprep: // EM/MH \\ |
| | 55 | - Cultures appeared to have survived. |
| | 56 | - Results will be ready before the next meeting |
| | 57 | |

| | 63 | - Ross' last meeting :( |
| | 64 | |
| | 65 | === Summary of actions === |
| | 66 | - All the elements for the beamline are now in place |
| | 67 | - **TP (and others?):** Chase up no-cost extensions |
| | 68 | - **RW:** Cut and notch smaller RCF stack |
| | 69 | - **TP:** Overlay previous LET distribution on newer |
| | 70 | - **CD/AFR:** Verify G4 RCF stack |
