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

== Notes ==

1. //[wiki:Research/LhARA/RadiationBiology/Meetings/2025-02-20 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.
