At MSU, isotope center opens to unlock universe, revolutionize medicine
“This is the nuclear physics equivalent of the launch of the Webb Space Telescope,” Sherrill said, referring to the 2021 launch of the most powerful telescope ever placed in space.
“That’s a new tool that astronomy never had to look at the atmospheres of planets and stars and distant galaxies. This is a nuclear physics equivalent, being able to see and explore kinds of atoms that we never could before.”
Bridge Michigan spoke to Sherrill and FRIB lab director Thomas Glasmacher recently about the impact the facility will have on Michigan and the world. Oh, and whether a careless grad student could create a black hole.
What’s a FRIB?
FRIB houses the world’s most powerful heavy-ion accelerator. It is a complex of four buildings, with an underground tunnel housing the accelerator. That tunnel is 570 feet long, nearly the length of two football fields, and is 70 feet wide, 12 feet high, and 32 feet under the ground of the MSU campus.
The accelerator propels atoms to half the speed of light to collide with a target. The resulting collisions produce combinations of protons and neutrons that aren’t normally found on earth and don’t hold together forever, called rare isotopes.
Just how rare are these isotopes?
Many are not found on earth, and only believed to exist in stars. Researchers believe the speed of the accelerator will help scientists find as many as 1,000 new rare isotopes.
“The discovery opportunity is related to the power of the beam because if you have more powerful beams, you can make more exotic rare isotopes,” Glasmacher said. “It’s almost like an Easter egg hunt. You know there are some eggs over here, but you find eggs in places you didn’t expect. There are areas of research we know about, but there will be discoveries we make that we don’t know about yet.”
How will FRIB research impact our lives?
Past discoveries of rare isotopes have been crucial in developments from smoke detectors to PET scan imaging for disease, to radioisotope dating of ancient earth history.
One area in which Glasmacher said he feels confident the facility will make breakthroughs is in medical research.
“We’re not a hospital, but we can make these isotopes for researchers who develop therapies, and we can do it quickly,” Glasmacher said.
What does this research have to do with the stars?
Sherrill said work at the FRIB is likely to help researchers understand the evolution of the universe.
Most of the elements in nature are created in stars and stellar explosions, and there are additional elements made in those stellar explosions that are not normally found on Earth. Rare-isotope accelerators like the one at MSU will be able to create some of those rare isotopes, which could help us understand what the first stars in the universe were like.
Who does the research?
Even before the FRIB opened, MSU had the nation’s top-ranked graduate program in nuclear physics program, training one in 10 of the country’s doctoral students in that field.
Beyond undergrad and grad students, “at any given time, we might have 100 or so scientists on site” from around the world, Sherrill said.
Most research projects take about three weeks, but some take months. “We are good for the local hotels,” Sherrill joked.
Is there an economic impact for Michigan?
The facility will employ about 1,000 people permanently, and pump $4.4 billion into the Michigan economy over 20 years, according to a 2017 study.
A positive side-effect of the new facility is it will likely draw more highly educated people to live in the state, Sherrill said. “All these people come to Michigan (to study or conduct research), hopefully some of them will stay.”
Could it blow up or create a black hole?
Glasmacher said he’s heard people in the community worry an experiment gone sideways could cause some kind of global catastrophe – a nuclear explosion or “black holes and, you know, the world going away,” Glasmacher said.
“That’s not going to happen.”
Because particles used in the accelerator are isolated rather than condensed like in an atomic bomb, there won’t be any mushroom clouds over East Lansing.
Why is this such a big deal?
“It was something like 30 years ago, when we got to a point in nuclear physics where we realized that we weren’t going to make progress unless we had a much expanded ability to explore the atomic nucleus,” Sherrill said.
