Abstract
Earlier papers (1) (2) have demonstrated that the entrapment of helium in tungsten is strongly dependent on the presence of lattice damage. It was concluded (2) that the entrapment proceeds via the interstitial diffusion of injected helium at room temperature, and that any helium atoms not encountering a defect during their diffusion escape through the surface. Considerations of helium ion penetration depths suggested that a trap concentration as low as ~10-9 should have been detectable when the bombardment area was about 0.1 cm2.
