This thesis details the experimental studies leading to initial attempts to measure an interaction in free space between a short pulse of terahertz radiation (generated from a 40 fs, 800 nm titanium-sapphire (Ti:S) laser pulse) and bunches of medium-energy relativistic electrons within the ALICE accelerator. The work undertaken included optimization of the terahertz source itself, which is a large-area photoconductive antenna with high-voltage electrodes; the aim being to maximize the potential that can be applied before breakdown occurs. The key feature of such terahertz sources is the radially-polarized (TEM10-like) nature of the radiation generated. Further work included characterization of the temporal structure and transverse profile of the terahertz radiation pulse in the ALICE Diagnostics Room; duplication of this experimental arrangement inside the ALICE accelerator; modification of the operating parameters of ALICE to produce the most conductive situation for detecting an interaction. The final step was the installation of additional electron beam diagnostics and the experimental search for a definite interaction signal. The work described in this thesis is part of a project named ALICE Energy Modulation Induced by Terahertz Radiation, also known as AEMITR.
