The Mediate-energy Irradiation Terminal is an experimental terminal located at the Sector Focused Cyclotron (SFC), and is abbreviated to "SFC-T1".
SFC-T1 has the following three functions. First, the energy degradation function, which enables the dispersion of the kinetic energy of the incident mono-energy heavy ions into several tens of gradually decreasing values. The energy gradient can cause a quasi-uniform depth distribution of defects and implanted atoms in specimens, making possible for precise investigation of changes of microstructures and material properties caused by ion beams. Second, specimen temperature control function. The unit includes a liquid-nitrogen cooling stage and a high-temperature stage (up to 600 degree Celsius), making possible the control of specimen temperature during ion irradiation. The specimen stages also have lift/rotation function enabling irradiation of up to fifteen specimens in a batch. Third, scattered ion beam irradiation function, which enables irradiation to broad doses lower than 1x1011 ions/cm2.
The researches being carried out at SFC-T1 are in two aspects. First, radiation damage of materials candidate to advanced nuclear power plants. Second, radiation effects of novel photonic / optoelectronic materials.
