On Wednesday evening a two-alarm fire broke out at the SLAC National Accelerator Laboratory, less than a mile from Stanford campus.
According to a post on KTVU news, a transformer attached to the accelerator reportedly caused the fire.
The flames were first sighted just before 10 p.m., and the Menlo Park Fire Department reported that smoke was dissipating by 10:30 p.m.
Authorities announced that they had contained the blaze shortly afterward, and fire officials worked with staff on site to ensure that the accelerator was isolated and safely shut down.
