ROLE OF IONIZATION IN RADIATION ANNEALING
Technical Report
·
OSTI ID:4063615
The role of ionization in the phenomenon of radiation annealing of graphite was stadied by using a 1-Mev electron beam. Changes in the c-axis of a sample with a Hanford irradiation of 460 mwd/ct were studied. Two thermal anneals of 4 hours each at 350 deg C proved sufficient to complete the thermal annealing at this temperature. The samples were then irradiated for 7 1/2 hours at a temperature of 340 deg C. The samples received an irradiation of 47 microamperehours, equivalent in ionization to sn exposure of 200 mwd/ ct in a Hanford reactor. No changes were noted as a result of the electron bombardment. It is concluded that the ionization is not of major importance in radiation annealing. (auth)
