Meet the undulators that will revolutionize scientific research!
Berkeley Lab #engineers have created nine new #undulators and retrofitted 21 existing undulators for SLAC's LCLS-II-HE upgrade. The first photo shows a completed undulator; the second photo shows the magnetic undulator components.

Happy birthday to Ernest O. Lawrence, founder of @berkeleylab.lbl.gov, born August 8, 1901. He received the Nobel Prize for inventing the cyclotron, an antecedent of the modern-day ALS. He also pioneered the concept of Big Science – an approach we still follow! Watch a short video: bit.ly/3HbKjUW

#MechanicalEngineering Technician Nathan Seidman examines connections on the assembly for GRETA. “The assembly is quite beautiful in a scientific sort of way, so even when I am shoulder-deep and frustrated, trying to access a buried liquid nitrogen line, it's never too bad of a time,” Seidman says.
