“…As the vertical gap required between the poles of the new Superbend dipole was lower than those of the standard electromagnetic dipoles, it was not possible to keep the common first dipole part of the vacuum vessels as designed. As the quadrupole part should be identical, the original design was kept (Filhol, 2004;Level et al, 2003Filhol et al, 2006) and only the dipole part was adapted to the new gap requirement (Fig. 12).…”

“…As well as the difficulty in accommodating a very low vertical gap for the 2.8 T magnetic bore, the complementary 'low-field' part of the Superbend dipole also needed a lower gap than the actual one because a magnetic field slightly higher than 1.7 T was needed to reach the nominal total field integral. Nevertheless, the dipole part was designed on a similar principle as the actual one (Filhol, 2004;Level et al, 2003Filhol et al, 2006), keeping the same manufacturing scheme in two half shelves, assembled with an electron beam welding in the median plane. This allows the shape to be adapted to both magnetic gaps and electron beam path (Fig.…”

In August 2021, the SOLEIL storage ring was restarted after the summer shutdown with a new bending magnet made entirely of permanent magnets. Producing a magnetic field of 2.8 T, it replaced one of the 32 electromagnetic dipoles (magnetic field of 1.7 T) of the ring to allow the ROCK beamline to exploit more intense photon fluxes in the hard X-ray range, thus improving the time resolution performances of the beamline for experiments carried out above 20 keV. The reduction of the new dipole magnetic gap required to produce the higher field has led to the construction and installation of a new vacuum vessel. The realization of the new dipole with permanent magnets was a technological feat due to the very strong magnetic forces. The permanent-magnet assembly required dedicated tools to be designed and constructed. Thanks to accurate magnetic measurements, a precise modelization of the new dipole was performed to identify its effects on the electron beam dynamics. The first measurements carried out on the ROCK beamline have highlighted the expected increase in photon flux, and the operation performances remain unchanged for the other beamlines. Here, the major developments and results of this innovative project are described in terms of technology, electron beam dynamics and photon beam performance on the ROCK beamline.
