An electrical incident occurred on the SLAC site in late December. A site-wide safety stand down ensued to review and improve operating procedures across the site - with particular emphasis on hazardous energy (CoHE) protocols and lock-out-tag-out (LOTO) restrictions. These restrictions applied to restarting the injector and SPEAR3 for SSRL operations. The situation was further compounded by a SPEAR3 injector transformer failure on January 11. New procedures had to be approved by the Department of Energy before any CoHE or LOTO work could be done. Work on the transformer has begun, and we hope to be able to restart SSRL operations in early July. We realize that this unexpected outage has had significant impact on our user community, and we sincerely appreciate your patience.
