We report the magnetic design of twin resistive magnets, with a field configuration applicable to large lepton colliders, like FCC-ee. The bending magnets are based on an I-layout, with a common iron yoke powered by two busbars; both pure dipoles and combined function units with an embedded gradient are considered. The quadrupoles present a peculiar geometry, with eight poles but only two...

The latest CLIC damping ring lattice is based on magnets with longitudinally variable dipole fields in order to achieve ultra-low beam emittance, while keeping the ring circumference small. These magnets need to provide a focusing gradient of 11 T/m as well. The good field region radius is 5 mm. The field harmonics shall be in the order of 1E-4 of the main one. Since only a small variation of...

Laser-target acceleration represents a very promising alternative to conventional accelerators for several potential applications, e.g. in nuclear physics and medicine. However, some extreme features, such as a wide energy and angular spread, make optically accelerated ion beams not immediately suitable for multidisciplinary applications. Therefore, in addition to improvement of laser-target...

A test facility for storage ring based high energy photon source with a beam energy of 6 GeV, a circumference about 1300m, and an emittance about 59 pm•rad (HEPF-TF) is now under construction in china. Small aperture high gradient quadrupole magnets are important magnets in HEPS-TF. The design and manufacture of two prototype high gradient small aperture quadrupole magnets are finished. The...

The new magnet lattice of the European Synchrotron Radiation Facility (ESRF) will include 128 Permanent Magnet (PM) dipoles presently under in-house construction. It requires about 6 tons of high coercivity Sm2C017 permanent magnet material subdivided into 12,300 blocks. The choice of the permanent magnet technology is motivated by an energy-saving context, the compactness of the magnet...

Permanent magnet (PM) based systems offer a potential solution to one of the key issues in designing and running modern particle accelerators; the power draw from conventional electromagnet systems. A recent and ongoing collaboration between the CLIC project at CERN and STFC’s Daresbury Laboratory has resulted in the ZEPTO (Zero Power Tuneable Optics) project, a drive to reduce the financial...
