Helium isotope exchange in tungsten during sequential irradiation by 3He and 4He ions at room temperature was investigated. Tungsten samples were irradiated in two ways: by 3 keV mass-separated ion beams, or by low energy ions in plasma discharge. The He amount in W after irradiation was measured using ex-situ (up to 2500 K) thermal desorption spectroscopy. Despite the very high binding energy of He with lattice defects in W, a very high efficiency of He isotope exchange was observed.
