  Several groups internationally have been designing and building adjustable permanent magnet based quad-rupoles for light sources, colliders, and plasma accelera-tors because of their very high gradients and zero power consumption. There are now examples of widely adjusta-ble PM dipoles too. The ZEPTO project, based at STFC Daresbury Laboratory, developed several highly adjusta-ble PM-based dipole and quadrupole prototypes for CLIC, and is now building a quadrupole to be installed in Diamond to gain experience ahead of the Diamond-2 upgrade. This is a review and comparison of the recent designs globally with comments on the future prospects.

  Sirius is a 4th generation 3 GeV low emittance electron storage ring that is in final commissioning phase at the Brazilian Centre for Research in Energy and Materials (CNPEM) campus in Campinas, Brazil. Presently (April 2020) we have accumulated 15 mA of current, limited by vacuum, using a nonlinear kicker for injection. In this paper we report on the Sirius main commissioning results and main subsystems issues during installation and commissioning.
