“…The system consists of an inner hybrid ring with 8 sectors Halbach system and the outer ring being a pure 12-magnet Halbach structure rotating around the first one resulting in gradient variation from 17 T/m up to 120 T/m for a 230 mm magnetic length and 10 mm bore radius [45]. • A super hybrid quadrupole combining permanent magnetic material, coils and soft magnetic material has been built (see Figure 10) and tested for the new Brazilian Synchrotron Light Source (Sirius) [46]. The system has a bore radius of 27.5 mm and a magnetic length of 288 mm providing a maximum gradient of 28 T/m with a 30% tunability.…”

The laser plasma accelerator has shown a great promise where it uses plasma wakefields achieving gradients as high as GeV/cm. With such properties, one would be able to build much more compact accelerators, compared to the conventional RF ones, that could be used for a wide range of fundamental research and applied applications. However, the electron beam properties are quite different, in particular, the high divergence, leading to a significant growth of the emittance along the transport line. It is, thus, essential to mitigate it via a strong focusing of the electron beam to enable beam transport. High-gradient quadrupoles achieving a gradient greater than 100 T/m are key components for handling laser plasma accelerator beams. Permanent magnet technology can be used to build very compact quadrupoles capable of providing a very large gradient up to 500 T/m. We present different designs, modeled with a 3D magnetostatic code, of fixed and variable systems. We also review different quadrupoles that have already been built and one design is compared to measurements.

“…(8) There is the need of shielding as a safety procedure due to mechanical forces exerted on ferromagnetic materials. Some publications have already handled the use of PMMs for Sirius storage ring [17][18][19]. However, a deep change in the project reduced the emittance by one order of magnitude, giving a new opportunity for many improvements as well as better consolidation of the concepts developed for this innovative idea.…”

“…The main parameters for the quadrupoles of the Sirius storage ring are in Table 2. Two models are proposed: one is the conventional electromagnetic and the other one is a super hybrid model [19] (Fig. 14) using PMMs.…”

The new Brazilian Synchrotron Light Source (Sirius) is under development and will operate at 3 GeV, with 0.5 A and emmitance close to 1 nmrad. "Green solutions", using permanent magnets, are being proposed for the dipoles and quadrupoles of the storage ring. This is an attempt to reduce as much as possible the electrical energy consumption, trying, at the same time, to assure the reliability of the magnets during several years. Results of some prototypes already built and characterized are presented in this report.
