"Three petawatts is 3,000 times more powerful than the U.S. power grid. And 3 petawatts is 3 with 15 zeroes after it."
9. Various of McKelvey inspecting a prototype vacuum compatible mirror mount
ANNOTATION: There will be no cost to users whose experiment proposals are selected, beyond providing their own travel costs to the facility.
ANNOTATION: ZEUS primarily will study extreme plasmas, a state of matter in which the electrons have enough energy to escape atoms.

"We're going to be studying a range of different physics with ZEUS. So, this will vary from studying how we can accelerate particles. Particle accelerators and light sources have a huge range of applications across science, technology, engineering and medicine."

STORYLINE:
A newly constructed University of Michigan facility that will be home to the most powerful laser in the United States is hosting its first experiment this week as the nation seeks to become competitive again in the realm of high-power laser facilities.
The experiment will be conducted at ZEUS — short for Zettawatt-Equivalent Ultrashort pulse laser System — by researchers from the University of California, Irvine. They traveled to Ann Arbor as part of their study of extremely intense interactions of light and matter, and how such interactions can be harnessed to shrink particle accelerators.
At the height of its power, ZEUS will be a 3-petawatt laser.
