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
• Analysis of SOBP data, results shown in this presentation
• Preliminary testing of 2nd order Birks' Law, results shown in this presentation
• Presented on I/O signals and operation of TI DDC232CK based on datasheet information. Slides available here.
• Wrote code to interface FPGA with DDC232 and tested in simulation. Results of simulation discussed here.
• Interfaced DDC232 code with a UART transmitter, discussed UART interface 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.
