	Funding: This work was supported by Lawrence Berkeley National Laboratory under U.S. Department of Energy Contract No. DE-AC02-05CH11231. The ALS in now engaged in the construction of a new hard x-ray beam line and insertion device for protein crystallography. The scope of work entails the reconfiguration of ALS Sectors 1-3 to make room for the new insertion device. The project will require the melioration of the ALS injection system as well as the development of a longitudinal RF kicker. A key aspect of the injector work is the development and integration of a nonlinear injection kicker (NLK) magnet system to facilitate top off injection without noticeable motion of the beam. The technology will, in principal, ultimately allow the removal of the conventional bump injection magnets presently located in ALS Sector 1. The nonlinear injection concept has been explored at several other light sources . We examine the beam dynamics and magnet design requirements to adapt this technology to the ALS lattice with its 1.9 GeV beam. The work will review the injection beam matching, tracking simulations, the electromagnetic design and tolerance analysis, power supply design. The paper will also review the project plan for the integration of this technology into the ALS. T.

	Funding: This work was supported by the Laboratory Directed Research and Development Program of Lawrence Berkeley National Laboratory under U.S. Department of Energy Contract No. DE-AC02-05CH11231. Improvements in brightness and coherent flux of about two orders of magnitude over operational storage ring based light sources are possible using multi bend achromat lattice designs. These improvements can be implemented as upgrades of existing facilities, like the proposed upgrade of the Advanced Light Source, making use of the existing infrastructure, thereby reducing cost and time needed to reach full scientific productivity on a large number of beamlines. An R&D program funded by internal laboratory funds was started at LBNL to further develop the technologies necessary for diffraction-limited storage rings (DLSR). It initially involves five areas, and focuses on the specific needs of soft x-ray facilities: vacuum system/NEG coating of small chambers, injection/pulsed magnets, RF systems/bunch lengthening, magnets/radiation production with advanced radiation devices, and beam physics design optimization. Some hardware prototypes have been built. The work will expand in the future to demonstrate necessary key technologies at the subsystem level or in beam tests and include new areas like photon beamline optics.
