Abstract
Heating of MgO crystals exposed to repetitively pulsed ion beams is studied. A solution to the thermal-conductivity equation provides induced specimen-temperature variations about a mean with irradiation-pulse repetition rate. The average temperature during the variation period first increases and then saturates, approaching a quasi-stationary value <T>. The latter depends entirely on the thermal resistance of the specimen–substrate contact under fixed irradiation conditions. A rapid method for determining the thermal resistance of the contact is put forward. The approach is based on repetitive pulsed heating of the specimen by a moderate-density electron beam and on precision measurements of average temperature.
