GSI (Darmstadt) together with a large international scientific community, among the members of which is the Budker Institute of Nuclear Physics, are engaged in the development of equipment and the construction of the CR (Collector Ring), which is part of the FAIR project.
Detailed calculations of CR in the isochronous mode show that the inhomogeneity of magnetic fields in dipole magnets...
Construction of a new primary proton beam line, which is called B-line, started in 2013 at the J-PARC Hadron Experimental Facility. The B-line is branched at the middle of an existing primary proton beam line (A-line) in the beam switching yard (SY), which is the connecting tunnel between the Main Ring (MR) and the Hadron experimental hall (HD-hall). At the branching point, about 0.1% of the...
Abastract: Currently, a new gas-filled recoil separator Spectrometer for Heavy Atoms and Nuclear Structure 2 (SHANS2) is being developed and designed at IMP (Institute of Modern Physics, Chinese Academy of Sciences). It will be used to synthesize and study the superheavy elements, including their physical and chemical properties. The SHANS2 include two dipole magnets and three quadrupole...
FASER, the ForwArd Search ExpeRiment, is designed to search for new, yet undiscovered, light and weakly-interacting particles and study the interactions of high-energy neutrinos. Three dipoles are required to achieve sufficient separation of pairs of oppositely charged, high-energy Standard Model particles originating from decays of new physics particles. The first magnet is 1.5-m-long and...
We have been developing radiation-resistant warm magnets insulated by a Cyanate ester resin. We developed a glass fiber cloth prepreg tape using Cyanate-ester pre-polymers supplied by Mitsubishi Gas Chemical Corporation INC. The proton beam irradiation test was carried out for the evaluation of the radiation hardness. We prepared cured resin samples of Cyanate ester, Bismaleimide Triazine...
The storage ring of Hefei Advanced Light Facility(HALF) will employ high-gradient quadrupoles for the sake of diffraction limit, the typical gradient values of them arrive at 60-80 T/m, the saturation on the pole tip is very serious. Moreover, the gap between two adjacent poles should have a certain interval to accommodate light box, which is equal to reduce the pole width. All the cases...
