The angle γ is a fundamental parameter of the Standard Model, within which it quantifies the degree to which CP violation is permitted. It is presently one of the least well-constrained parameters of the CKM sector, which embodies the description of quark interactions. This thesis details work undertaken by the author at the LHCb experiment with the aim of reducing the uncertainty in γ. In addition, work undertaken to ensure the continued performance of the RICH subdetectors of LHCb is described. These subdetectors form a crucial part of the particle-identification system of LHCb, whose accuracy allows the precise study of processes with hadronic final states, such as the decays mentioned above.
