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.
