The electricity that runs the Laboratory’s experiments and facilities. “AC” stands for the alternating current that comes from large power stations. The term compares with “DC,” for “direct current,” which comes from sources like batteries.

Panel ensures safe operation of the $94 million NSTX Upgrade

Like a new passenger jet or power plant, the National Spherical Torus Upgrade (NSTX-U) must be certified safe to operate. At the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), the task of evaluating the safety of the $94 million upgrade belongs to the Activity Certification Committee (ACC), whose work remains ongoing. “This is a critical group,” said Adam Cohen, deputy director for operations at the Laboratory. “When you have a complex activity like the upgrade you need a standing committee to guarantee that it will run safely.”

PPPL lends General Electric a hand in developing an advanced power switch

Scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) are assisting General Electric Co. in developing an electrical switch that could help lower utility bills. The advanced switch “could contribute to a smarter, more advanced, more reliable, and more secure electric grid,” according to the DOE’s Advanced Research Projects Agency-Energy (ARPA-E), which is funding the GE project.
