HI-13 tandem accelerator in 1994 and 1995

HI-13 tandem accelerator was performed well in 1994 and 1995. The beam time for experiments was 3700 h and 3510 h, respectively. Some important improvements on the machine have been done. A complete home-made laddertron for the charging system of the machine has been developed and had been running for more than 6800 h. Development of home-made voltage divider resistor system for the accelerator has been completed, and as many as forty three percent of the total voltage divider resistors on the tandem was replaced by the home-made ones. A new beam line for the atom and molecule physics has been set up. To improve the measurement accuracy and efficiency of the accelerator mass spectrometer (AMS) facilities based on the HI-13 tandem accelerator, an automatic cycling injection system and beam measurement devices controlled by a computer for ratio measurement of related isotopes was set up. For material irradiation, facilities with both electrical and magnetic scanning devices for heavy ions were established
