Last updated 29/04/20

High Priority

• Data analysis
  • Analyse SOBP data from HIT April '19.
  • Add information to PBT Wiki on how to analyse simulated data and data taken from telescope.
  • Investigate second-order expansion of Birks law to improve performance at high dE/dx.
• Detector simulation
  • Set up parallel basic GEANT4 example in order to incrementally rebuild QUARC simulation.
• FPGA programming
  • Run Vivado tutorials with Zybo Z7 board and output clock signal from board.
• Heavy-ion fitting
  • Finish reading papers and get in touch with Lenny to discuss next steps.
  • Acquire HIT FLUKA tables for He, C and O beams.

Low Priority

• Set up Eclipse to work with ROOT on Windows partition of DAQ laptop.
• Assist Raffaella in photodiode front-end development of new detector prototype.

PhD Year 1 Completed

• Review of literature given by Laurent
• Delivered MSci presentation to PG Physics Society.
• Set up environment in Eclipse for analysis code to fit Bortfeld and quenched Bortfeld Bragg curves to simulated data and data from range telescope.
  • Tested analysis routines on simulated and raw data.
• HEP PG courses in term 1: SM1, SM2 & topics in particle physics.
• Medical physics course in term 1: Treatment with Ionising Radiation.
• Passed Standard Model exams: 80% SM1 and 48% SM2.
• Analysis of effects of beam spot size on range reconstruction from April 2019 HIT data, also with photodiode approximation. Results shown in this presentation
• Medical physics courses in term 2: Radiotherapy Physics & Medical Imaging with Ionising Radiation.
• Installed GEANT4 locally on MacOS High Sierra and Catalina, set up environment in Eclipse.
  • Can successfully run simulation of range telescope with different parameters and analyse output data.
• Fully implemented Laurent's analysis code and made improvements for better code practice, better parameter estimation and started framework for He and C fitting.
• Analysis of performance of quenched Bortfeld model with heavy ions, results shown in this presentation

MSci Completed

• Literature review.
• First Birmingham experimental run.
• Wrote code to load and plot Caen digitiser data in histograms.
• Overhauled LeCroy data analysis routines: (short region) double baseline sigma testing, dynamic integration window allocation, empty acquisition checks.
• Wrote code to scale and plot LeCroy & Caen data onto single plot, using approximate x and y-scale factors.
• Wrote code to load and plot PRaVDA data in 2D histograms.
• Wrote code to correlate tracker and calorimeter measurements, to produce a list of events with X, Y, E coordinates.
• Wrote code to plot matched events into various 3D histograms: XY, XE, YE.
• Progress report.
• Progress interview.
• Improved LeCroy & Caen matching by finding x-scale factor through chi-square minimisation.
• All runs from first Birmingham put through matching algorithm. Energy spectra, 2D tracker histograms, and 3D XY, XE & YE histograms plotted for all runs (187 plots).
• Wrote code to plot 3D XY histograms, but with the height of bars being the average energy in the bin.
• Improved LeCroy & Caen matching by finding y-scale factor through chi-square minimisation or through peak event counting. Peak event counting method best.
• Converted energy to range in XYE histogram.
• Plotted 2D number density histogram alongside 3D XYRange histogram.
• Produced poster for PPRIG 2019 of experiment with single-module calorimeter and PRaVDA tracker.
• Attended PPRIG 2019.
• Completed MSci Final report.
• Delivered presentation on project.
• Attended PTCOG 2019.
