Accelerator Laboratory

In 1956, National Tsing Hua University (NTHU) was reestablished on its current campus in Hsinchu, Taiwan. At that time, NTHU launched the Graduate Institute of Nuclear Science (INS), which initially consisted of three divisions. In 1958, President Mei Yiqi placed an order with HVEC for a KN Van de Graaff accelerator. In the same year, INS formally organized three divisions: the Nuclear Physics Division, the Nuclear Chemistry Division, and the Nuclear Engineering Division. Concurrently, the Van de Graaff Accelerator Laboratory was established under the Nuclear Physics Division. In 1965, the Department of Physics was founded, evolving from the Nuclear Physics Division of INS. The following year, the Graduate Institute of Physics was established, offering both master’s and doctoral programs. The Van de Graaff Accelerator Laboratory was transferred to the Department of Physics and was housed in the old Physics Building, where it was operated by the department for 32 years. In 1990, under the initiative of Prof. Yuen-Chung Liu, then head of the Van de Graaff Accelerator Laboratory, and in response to the research needs of accelerator users, a proposal was made to expand services and update equipment with a tandem accelerator. With the university’s approval, the Accelerator Laboratory was officially established in January 1991. In 1995, the KN Van de Graaff accelerator was relocated from the old Physics Building to the newly designated Accelerator Building (formerly the Scientific Instrument Building). In March of the same year, a tandem accelerator (NEC 9SDH-2) was installed and began operation. In 1999, an open-air 500 kV ion implanter was transferred from another university to the Accelerator Laboratory and resumed operation in 2000. At the end of 2017, the laboratory further expanded its research capacity by acquiring a decommissioned NEC 9SDH-2 tandem accelerator from Academia Sinica’s Institute of Physics.
