✦ Synopsis

The simple chemical rate theory of irradiation damage in graphite is modified to take account of two effects:

(a) The mobility of vacancies parallel to the hexagonal axis of the crystal.

(b) The thermal annealing of the non-saturable sinks for point defects and the presence of the thermal equilibrium defect concentration.

The first of these is shown to be unimportant but the latter leads to the disappearance of damage at high irradiation temperatures(not yet observed).
