The Heavy Ion Research Facility in Lanzhou- Cooler Storage Ring (HIRFL-CSR), a flagship facility of basic research in China, passed the acceptance check under auspices of the State Development and Reform Commission on 30 July in Lanzhou, capital of northwest China's Gansu Province.
The Heavy Ion Research Facility in Lanzhou- Cooler Storage Ring (HIRFL-CSR), a flagship facility of basic research in China, passed the acceptance check under auspices of the State Development and Reform Commission on 30 July in Lanzhou, capital of Gansu Province. The event was jointly presided over by the Commission's Vice Minister ZHANG Xiaoqian and CAS Executive Vice President BAI Chunli.
Started in 2000, the construction of the 290-million-yuan facility was implemented by researchers from the CAS Institute of Modern Physics. Experts say that it will serve as a state-of-the-art experimental platform both for basic research in the fields of nuclear physics, hadrons physics, atomic physics, and high energy density physics and for applied research into heavy ion irradiation materials, heavy ion cancer treatment, and space radiation.
HIRFL-CSR consists of two rings: the main ring (CSRm) and the experimental ring (CSRe). The former is used to accelerate, cool and accumulate heavy ion beam while the latter is used as an experimental terminal for applied research. It is on a part with world-class complex of cool storage such as the on at GSI in Germany.
According to experts, the HIRFL-CSR will be able to provide stable nuclear beams, radioactive nuclear beams, highly ionized heavy ion beams and polarized beams of high quality and strength with different specifications and wide energy scopes. It will make more advanced experimental conditions available for high quality and accurate scientific experiments that will lead to new breakthroughs in the areas of basic studies of nuclear physics and atomic physics, exploration of new energy and cancer treatment by heavy ion beams.
In the meanwhile, HIRFL-CSR project will promote associated developments such as those of electronic cooling, pile-up of heavy ion beams, super thin inner target, super vacuuming, synchronized ion beam source of stripped electron of high currents and strength, fast tracking control, fast changing magnetic field, beam diagnosis.
Scientists say that it is on a par with the similar facilities of world-class like the one at GSI in Germany.
