Description

Thermal desorption spectroscopy (TDS) measurement of tungsten (W) exposed to tritium (T2) under a series of conditions was conducted, and the peak of T2 desorption reached as high as 895 K at the heating rate of 20 K/min. The detrapping energy of T in W was then determined experimentally to be 2.18 ± 0.22 eV, suggesting that T was mainly trapped by vacancy clusters which may be formed during manufacturing and enhanced by charged T atoms.
