This facility consists of negative ion sources, a 1.6 MV tandem Pelletron electrostatic accelerator (photograph) and a beam transport system. The electrostatic accelerator can deliver well-focused MeV ion beams with high energy-resolution to the target. Ions with mass-numbers ranging from A=1 to 100 can be accelerated. The typical beam current is 1 μA. Pulsed beams with a duration of 1 ns and a repetition frequency of 100 MHz are also available on demand. This facility is being used for the experiments on the interaction between heavy ions and hot plasmas concerning heavy-ion inertial fusion, as well as for the trace element analysis of environmental samples. Also energy-related advanced materials are investigated by means of ion-beam analytical techniques.
