The Ad­vanced Light Source (ALS) at Berke­ley Lab re­mains 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 ALS bright­ness up­grade, which re­duced the hor­i­zon­tal emit­tance from 6.3 to 2.0 nm (2.5 nm ef­fec­tive). Mag­nets for this up­grade were in­stalled start­ing in 2012 fol­lowed by a tran­si­tion to user op­er­a­tions with 2.0 nm emit­tance in spring 2013.
