LhARA radiobiology; meeting: 13Mar25; 14:00 GMT

Present: M.Hill, J.Parsons, R.Gray, K.Long, R.Razak, C.Whyte, C.Palmer, B.Sheppard.

Notes

1. Minutes and actions:

2. Field mapping, preparation of PMQs: HO/BS
   • Mapping done; needing now to document the measurements. Individual map probe points will be available. A grid field map can be provided, or, an interpolated map, analytical form etc.
   • Timeline: Still aiming for June/July.
     Actions:
     • RR/KL: Liaise with Will Shields and send to HO request for format of field map, e.g. B on grid with 0.5 mm pitch as starting point.

3. Mechanical design update: CH
   • Design of stands, kinematic mounts, stay-clear PTFE blocks advanced. Some details to be refined, then manufacture of plates can begin.
   • Note to continue to assembly in DL; discuss shipping timescale when orders for stages placed.
   • KL: ask C. Dyson to present error study at CM.

4. Bioprep: EM/MH
   • Carousel design updated; disc is larger and allows additional samples to be supported.
   • E. Melia is doing He ion irradiations at the moment using glass rings etc; investigations of benefit to SCAPA.

5. DoNM
   • 27Mar25

6. AoB
   • None.

Summary of actions

• RR/KL: Liaise with Will Shields and send to HO request for format of field map, e.g. B on grid with 0.5 mm pitch as starting point.
• KL: ask C. Dyson to present error study at CM.
