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).
