The Advanced Light Source (ALS) at Berkeley Lab is one of the brightest sources for soft x-rays worldwide. A multiyear upgrade of the ALS is underway, which includes new and replacement x-ray beamlines, a replacement of many of the original insertion devices and many upgrades to the accelerator. The accelerator upgrade that affects the ALS performance most directly is the brightness upgrade, which reduced the horizontal emittance from 6.3 nm to 2.0 nm (2.5 nm effective), resulting in one of the lowest horizontal emittances of operating light sources. Magnets for this upgrade were installed in late 2012 and early 2013 followed by successful commissioning and user operation with 2.0 nm horizontal emittance.
