Abstract
In this work, the W bulk prepared by powder sintering and W film deposited by magnetron sputtering were simultaneously exposed to the helium ions with the energy of 60 keV and fluence of 1.0âÃâ1022 mâ2 at room temperature. The surface modifications induced by the helium irradiation were studied by scanning electron microscopy. After helium ion irradiation, numerous blisters were observed on the surface of both samples, some of which burst in various degrees. The formation of blisters is attributed to the high gas pressure in the helium bubbles. In addition, the different structures between W bulk and W film lead to the differences in density and size of blisters.
