Meeting Notes

1. In-Person Meeting

• Date: 24th Feb at Birmingham
• Room Booked
• Start at 10:30am
• Schedule needs adjusting to fit this
• Narender to present on air scintillation
• Send confirmation email to all invited

2. LION Simulations

• Show that for a ~330T/m the precision to cause unusual beam shapes is:
  • microns in transverse offsets
  • millimeters in longitudinal offsets
  • microradians in rotation about the x- and y-axes
  • milliradians in rotation about the z-axis
• Check the resolution of the positioning of PMQs at SCAPA

2. DoNM

• 5th Mar 14:00

7. AoB

Summary of actions required

Phase 2 Analysis

• EM: Evaluate the cell results
• CD, AFr: Complete analysis of RCF with errors
• EM/ED/LJ: Send calibration films to SCAPA and scan them in both orientations
  • CD, RW and AFr: Explain scanning procedure
• EM, JMcG: Write up summary of PoPLaR Phase 2, including technical summary of cell irradiation procedure
• MB: Comet analysis
• CD: Invite Liverpool, Chris Armstrong and LMU to join the in-person meeting

Beam Diagnostics

• Unassigned: Find all the errors associated with RCF
• RW, CD: Study correlation between laser diagnostics and mean dose
• CD, TP: Evaluate LET in the cells with the RCF in front

Improve Bio results

• EM: Inform Roshine when to defrost Glioma cell line
• Unassigned: Obtain an inverted microscope

Long-term

• CD, JMcG: Investigate how to achieve uniformity without a scatterer in place
• KL, CW: Cost 4 or 6 quad, and chicane systems
