Novel Magnet Lattice for the High-brightness Upgrade of NSLS-II
Abstract The main trend in the decades-long evolution of synchrotron light sources is continuously increasing photon beam brightness demanded by the user community. Since reducing the electron beam emittance is a straightforward way to increase the brightness, new and upgraded synchrotron light sources are now based on the multi-bend achromat approach providing much lower emittance than synchrotrons of previous generations. For the high-brightness upgrade of NSLS-II, we designed a low-emittance lattice based on the novel concept of complex bends. Key advantages of this lattice are the use of permanent magnets reducing power consumption and compact magnet design providing longer straight sections for light-generating insertion devices. For this lattice, we estimated the lowest possible emittance at the operational beam intensity taking into account collective effects of beam dynamics.
