Low emittance machines require lattices with many magnets of short length. Furthermore, successful lattices require strong gradients with strong dipole fields. These lattices are popular today, as MAX IV has demonstrated that a diffraction limited synchrotron light source can be based on such a lattice.
This paper gives an overview of the various magnets used by the different diffraction...
RF system is one of the key components of a 2 GeV, 6 MW high power FFAG accelerator being designed at China Institute of Atomic Energy. In order to verify the design principle and the engineering feasibility, a small scaled RF cavity is under construction, which can also be used as the main accelerating cavity for a 100 kW electron irradiation accelerator. By the deflections of several 180 deg...
Abstract: The High Energy Photo Source (HEPS) is been built in China and the magnets are in batch production. The octupole magnets with skew quadrupole component used in the storage ring have been designed and manufactured. This magnet has an aperture of 30mm, a field gradient of 735000 T/m3 and a length of 0.26m. Different design schemes are compared. The magnet consists of 2 yokes and 4...
The results of the development of a magnetic system for bending an electron beam in the industrial accelerator ILU-10 will be presented.
The ILU-10 accelerator has an operating energy range of 2.5–5 MeV. The available design allows to eject electrons only vertically. However, there is a demand for the ability to eject a beam bended at 90 °.
The paper presents two ways to solve this problem....
In order to design a pulsed electromagnet, it is necessary to consider eddy currents that depend on the pattern shape of the pulse excitation, and to design the structure and set the operating parameters considering the fluctuation of the magnetic field distribution and its effect on heat generation. Evaluation tests of a new bump magnet for the J-PARC RCS showed that the magnetic field...
The electron cooling technology is applied in the spectrometer ring (SRing) for HIAF to boost the luminosity of high-density beam. There are 4 kinds of main coils are used to offer longitudinal field along electron path. In this paper, the three-dimensional magnets of the electron cooler are analyzed. The model consists of a gun section, two 90° angle toroids with a radius of 1 m, a cooling...
The Helmholtz Zentrum Berlin (HZB) developing a new synchrotron light source, BESSYIII, as successor to the excellent 3rd generation light source BESSYII. The BESSYIII storage ring will be designed for a beam energy of 2.5GeV and Multi bend achromat (MBA) optics for low emittances of 100pm-rad. In parallel to optimizing the optics of the MBA cells, we are starting to develop various magnet...
The Neutron Spallation Source (SNS) at ORNL upgrade from 1.0 GeV to 1.3 GeV is in progress now. There are number of water-cooled magnets which should be upgraded to transport 30% of higher beam energy. There were designed new Chicane Magnets, Injection/Extraction Septum Magnets, and Lambertson Magnet. The magnetic designs were a challenging task because new magnets must have a good combined...
