SD Mines Researchers Help Ensure a Clean Signal in Next-Gen Dark Matter Detector at Sanford Lab

The LUX-ZEPLIN (LZ) dark matter detector in the Sanford Underground Research Facility (SURF) in Lead reached a major milestone this week. U.S. Department of Energy approval for the final design of the LZ experiment launches the construction phase and pushes the project toward the completion goal of April, 2020. Next-gen dark matter detectors have become sensitive enough that researchers around the world are now more confidently racing to be the first to directly observe the existence of dark matter particles. LZ is in direct competition with two projects in Italy and China. Researchers at South Dakota School of Mines &Technology are playing a key role in the detection and removal of radon from the sensitive equipment to ensure LZ has the cleanest signal possible.

"Physicists at Mines are playing a role in one of the most exciting physics experiments in the world,” said SD Mines President Heather Wilson.

LZ is being placed almost a mile underground to reduce the impact of cosmic rays that can hide the potential dark matter signal. But other types of background radiation and contamination can also produce false signals and hurt the effort to detect dark matter. Researchers must painstakingly measure all components of LZ for naturally occurring radiation. One challenge is the removal of radon, a naturally occurring radioactive gas that could interfere with dark ...

New Grant Funds Researched-Based Economic Development

A new state grant and matching commitments totaling $342,424 are bolstering research-based economic development at the South Dakota School of Mines & Technology.

The funds, including a $200,000 grant from the Board of Regents, are being used to buy scientific instruments for existing projects. Among them are two research endeavors at the Sanford Underground Research Facility (SURF) in nearby Lead. A third project expands on the university’s current success to commercialize a biomass liquefaction process.

Over the past decade, SD Mines has been supporting efforts at SURF to build a strong expertise and infrastructure toward synthesis of high-value organic products from biomass. 

Details on the three projects impacted by this new funding:

  • Development of a novel system reducing the radon concentration underground at the Sanford Lab, enabling future experiments in this facility. This project is being led by Dr. Richard Schnee, associate professor in the Department of Physics.
  • Development of two low-background detectors that will provide new capabilities important not only for planned underground physics experiments but also for industrial applications, especially in semiconductor and nuclear security sectors. This project is being led by Dr. Juergen Reichenbacher, assistant professor in the Department of Physics.
  • Selective liquefaction of lignin and biomass wa...

Strieder Leads Sanford Lab CASPAR Team in Unlocking Secrets of the Universe

Mines physicist Dr. Frank Strieder is the principal investigator on the CASPAR experiment at the Sanford Underground Research Facility.

In a cavern buried beneath a mile of rock at the Sanford Underground Research Facility, a School of Mines team has spent the last year assembling an accelerator that could alter the scientific world with quiet bursts of energy.

The Compact Accelerator System Performing Astrophysical Research (CASPAR) experiment hopes to understand the origins of the universe by mimicking nuclear fusion in stars, studying the smallest scale possible to understand the largest scale possible.

Led by South Dakota Mines’ Dr. Frank Strieder of the Department of Physics, the team of scientists includes researchers from the University of Notre Dame and the Colorado School of Mines, as well as seven Mines students—three doctoral students and four undergraduates. Strieder designed the 45-foot-long accelerator and spent a year purchasing or machining parts and then assembling them.

Data collection is expected to begin within the next month.

The idea behind the experiment is to generate the type of energy inside a star, allowing scientists to understand how stars were formed and where they are in their lifespan, which could lead to other discoveries about life in the universe.

One kilometer away inside another cavity of the sprawling deep underground laboratory, Ray Davis observed for the first time 50 years ago that neutrinos came from the sun. Davis earned the Nobel Prize for his discovery.

“We know bas...
