Tungsten is a candidate material for divertor in fusion reactors due to its high melting point and good thermal performance [1]. Helium introduced by burning plasma and neutron irradiation in tungsten will possibly re-emit into the core plasma and affect the safety. Heat desorption behavior of helium in tungsten needs to be understood to estimate the amount of helium re- election. this work, the dose dependence of helium desorption behavior in
