SJ, RR' and MH need to register for [1].

JO:

• Group placement coming up with Valtech working on NHS patient data.
• Two HEP exams in January.
• Enrolled on Simon Arridge's Inverse Problems course.
• Working through CERN Geant4 examples.
• To Do:
  • Contact Adam Gibson and arrange meeting to discuss Birmingham scintillator measurements.
  • Ask Adam about building scintillator simulations in Geant4.

RR:

• Working through preliminary documents for patent application for Vassilios Albanis.
• Started testing new PCIe Thunderbolt enclosure for CameraLink card.
• Designed a logo!
• To Do:
  • Organise equipment in new boxes.
  • Get PCIe enclosure working.
  • Start learning analysis with Laurent.

LK

• Working on stuff.
• Heidelberg data stored on plus1 and relevant parts sent to Lennart Volz.
• Started looking into Heidelberg data:
  • Rough reconstruction of SOBP.
  • Seeing droop due to high quenching of light.
• To Do:
  • PTCOG abstracts and registration.
  • Detailed data analysis for Heidelberg data.
  • Prepare for school talk on 4/11/18.
  • Workshop on paper writing 7/11/18.
  • Start writing paper on proton calorimetry results.
  • Analyse Heidelberg beam mixing data.

JO:

• Been reading background on particle-matter interactions and Monte Carlo simulations.
• Spoken to Adam Gibson about importing more sophisticated geometries and input beam distributions.
• Still going through reading list provided by Jamie McClelland and Adam Gibson.
• To Do:
  • Build Geant4 simulations of Cherenkov emission in water and scintillation light output from scintillator block.
  • Clarify meaning of phase space in radiotherapy.

JG

• Written project outline for SJ to review.
• Waiting on SJ to make contact with UCLH QA experts.
• To Do:
  • Search for more information on QA techniques..
  • Follow up references from PSI paper.

SS:

• Made progress on reconstructing energy spectra from LeCroy waveform data from Birmingham experimental runs:
  • Modified baseline subtraction now finds peak of pulse.
  • Resulting spectra look very similar to Caen ADC spectra.
• To Do:
  • Check total number of protons in each peak for eyepatch data.
  • Send spectra to Tony Price.
  • Retrieve tracker data from Tony Price.

MH:

• Improvements to Geant4 simulations.
• Reconstruction much faster due to analytical reconstruction algorithm: helps to prototype simulations.
• Full reconstruction now working: simple phantom gives very accurate reconstruction with fan beam.
• Looked into labelling individual protons: ROOT truncates strings...
• To Do:
  • Transfer report almost finished: due Friday...
  • Set up large scale simulations on plus1.
  • Contact Simon Rit and Niels Krah to convert ITK images to DICOM.
  • Contact Jamie McClelland for DICOM image conversion and reconstruction tools.
  • Assign ID to each proton to speed up pre and post matching.
