Hydrogen TDS spectra and their relation to the conditions of implantation and retention of hydrogen in graphite materials

Based on the literature thermal desorption spectroscopy (TDS) data, TDS spectra of hydrogen were analyzed and classified by graphite materials and implantation conditions. Using our experimental results, all the spectra were recalculated to the equal heating rate of 5K/s. The peak positions in TDS spectra have been found to be related to irradiation conditions and to the type of hydrogen traps. An example of using the established regularities of the TDS spectra is given to obtain the data on hydrogen trapping and retention in graphite materials.
