Dr. Kimberly Palladino says, “We don’t know if we will find dark matter with LZ but in the worst case, by 2025, we may know more about what it isn’t.”
In the photo, UW-Madison postdoctoral researcher Rachel Mannino and graduate student Shaun Alsum do a test fit of a high-voltage ring in a clean room at the LZ test facility at SLAC National Accelerator Lab. The UW’s Physical Sciences Laboratory designed and fabricated these high-voltage test parts.

A unique high-speed camera, designed to capture the fleeting effects of gamma rays crashing into the Earth’s atmosphere, will soon be on its way from the University of Wisconsin–Madison to Arizona’s Mount Hopkins.
The highest energy photons in the universe are gamma rays that carry essential information capable of answering leading questions in astrophysics and particle physics. Thanks to an innovative technique combining aspects of astronomy and particle physics, it is possible to detect gamma rays from the ground, when they collide with Earth’s atmosphere and produce a fleeting (a few billionths of a second in duration) flash of blue Cherenkov light
