Preliminary experiments have been performed to investigate the effects of radiative cooling on plasma jets. Thin (3μm-5μm) conical shells were irradiated with an intense laser, driving jets with velocities >100kms-1. Through the use of different targets materials - aluminium, copper and gold - the degree of radiative losses was altered, and their importance for jet collimation investigated. A number of temporally-resolved optical diagnostics was used, providing information about the jet evolution. Gold jets were seen to be narrower than those from copper targets, while aluminium targets produced the least collimated flows.
