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.

Sani’s Study of Extremophiles Welcomes International Collaborators, Gains Recognition

Dr. Rajesh Sani and his students have been collecting samples from the deep biosphere of the Sanford Underground Research Facility nearly a mile below ground.

Dr. Rajesh Sani’s research on how microorganisms can survive in extreme environments could lead to the conversion of solid wastes into bioenergy and the development of efficient, cost-effective green technologies.

In recent months his ongoing efforts have welcomed international collaborators from India and have been highlighted in SCI’s international Chemistry & Industry (C&I) Magazine.

The School of Mines and Sani, of the Department of Chemical & Biological Engineering, are currently hosting researchers from India for a year-long collaborative study on extremophiles such as those found a mile below the earth’s surface at the Sanford Underground Research Facility (SURF). The Sanford Lab in nearby Lead is located in the former Homestake Gold Mine and has 370 miles of tunnels. Of those tunnels, just 12 miles are maintained to house world-class laboratories where international dark matter and neutrino experiments are being conducted.

Over the past decade Sani’s group has been looking for thermophiles that can naturally degrade and ferment cellulose and xylan, a polysaccharide found in plant cell walls.

The extremophiles isolated from SURF by Sani’s group will also be used as test subjects in a new NASA study.
