1. Minutes and actions:

2. Update from SCAPA: RW, KL, CW \\
 [raw-attachment:2025-08-07-LONG.pptx Slides]

 - Two set ups tested – PMQ1 5mm closer to source – Strathclyde team trying to find a set up to get closer than the 105mm achieved
 - Beam shape changed as a function of energy as expected
 - Beam cross characteristic not a 90° angle
 - Beam cross disappears at 110mm – data at 115mm in simulation agrees
 - October run will be with a 2-PMQ set up, then move on to full 4PMQ (more uniform dose) at a later stage – main issue is funds for XYZ stages – possible difficulties with biology set up for this beam profile needs further discussion

3. Bioprep: \\
 - JP in contact with Fisher rep (Birmingham) and suggests orders can be made in Birmingham for delivery to SCAPA

4. DoNM 
 - 21st August 

5. AoB
 - ELI beam application to be discussed in future meetings
 - Book in dates for a biology (**EM**) and an instrumentation (**CD**) ‘dress rehearsal’ in SCAPA
