Proton Calorimetry/Meetings/2018/08/29

Minutes for UCL Proton Calorimetry Meeting, 29th August 2018 (D12, Physics & Astronomy, UCL)

Present

Matthieu Hentz, Simon Jolly, Saad Shaikh

MH:

• Managed to reconstruct CT phantom using Simon Rit's code:
  • Can generate images of stopping power values: used 270m protons in 3 hours, including reconstruction.
  • One anomalous point needs chasing up...
• Will email Simon Arridge and Jamie McClelland to arrange meeting and discuss.
• Made steps forward in understanding Reinhard Schulte's reconstruction algorithms: will email to get access to code.
• Need to think about comparison criteria.
• Has to give CDT talk on 17th September.

SS:

• Presented some background on the Fast Treatment Plan Verification experiments:
• Code now working to allow reconstruction of spectra with less user interaction.
• Tested scope with light pulser to check spectra reconstruction:
  • Results correlate for everything except 1MHz pulses.
  • Need to find out why 1MHz only reconstructed as 300kHz.
• Will set up equipment with SJ to test.
• Tony Price replied: will go for experimental test in October.

OM:

• Cleaned up Jordan Silverman's CAD model of Clatterbridge.
• Viewing in Adobe Acrobat with 3D CAD plugin: very neat!
• Disgarded obsolete or corrupted components.
• Need to include realistic dose monitors:
  • MH pointed out that housing should be square PMMA plastic.
