Yields of convoy electrons are measured at the transmission of 50 MeV 3He2+ ions through thick foils of C, Al, Ti, Ni, Mo, Ag, Ta and Au, Au foils coated with a thin C layer (<11 μg/cm2) and thin carbon foils (1.2-100 μg/cm2). It is shown that the convoy electron yield is proportional to the He+ fraction in the beam transmitted by the foil. The results are discussed with the two step model of convoy electron production.
