Key Points

  • This research aims to understand how high-fluence carbon ion irradiation affects the morphology and structure of graphite.
  • Conducted experiments using 30-keV carbon ions with a fluence of 1 × 10^18 ion/cm2.
  • Varied target temperatures from 50 to 600°C during irradiation.
  • Studied temperature shifts during dynamic annealing under continuous ion irradiation.
  • Found significant temperature shifts during dynamic annealing of HOPG.
  • Observed changes in morphology and structure under varying temperatures and ion fluences.
  • Highlighted the necessity of considering temperature shifts for simulating neutron irradiation in reactor-grade graphites.

Abstract

The effect of high-fluence irradiation on the morphology and structure of UPV-1T highly-oriented pyrolytic graphite (HOPG) using 30-keV carbon ions with a fluence of 1 × 1018 ion/cm2 at target temperatures ranging from 50 to 600°C is experimentally studied. The observed temperature shift during dynamic annealing under continuous ion irradiation of HOPG demonstrates the importance of taking this shift into account in methods for simulating the neutron irradiation of reactor-grade graphites, particularly at elevated temperatures.
