Title: Double Beta Decay with the COBRA Experiment. Supervisors: Dr. Y. A. Ramachers and Prof. P. F. Harrison

Developed a method for optimising passive shielding designs and applied it to the COBRA Experiment. Simulations were run using GEANT4 and MCNP.
Initiated development of an active shielding design for COBRA. Initially simulations were run but subsequent experimental work was conducted operating CZT crystals immersed in various liquid scintillators.
Experimental development work towards detector operation using the Frisch Collar method to improve energy resolution.
Data analysis work on “How many counts make a peak?” with regards to various peak finding algorithms applied to energy spectra.
