Visible HeI beam emission profiles have been measured at JET using 70 and 130kV pure and doped He beams in a radially swept high clearance L-mode plasma. The measured spectra are very clean with good spatial coverage. Altogether, the profiles of 7 different lines could be measured in plasmas with 1.5 Zeff 2.1. These profiles will be used to develop a reversion code extracting density- and temperature profiles from the He beam emission profiles.
