The world’s most powerful heavy ion accelerator, the world’s most powerful heavy ion accelerator, will create on May 2, will create new exotic atoms and reveal how stars and supernovae make up the elements that make up the universe, researchers announced May 2. Ours – finally done.
Experiments at the $730 million Facility for Rare Isotope Beams (FRIB) at Michigan State University (MSU) are scheduled to begin this week. Once online, the new reactor will fire two Nuclear each other, separating them in ways that allow scientists to study what binds them together and how rare the atomic isotope is – version of chemical element with different numbers of neutrons in their nuclei – have a structure.
While heavy ion accelerators of the past (such as the National Superconducting Cyclotron Laboratory, MSU’s former accelerator) allowed scientists to glimpse exotic atoms, they did not create generate them at a rate fast enough to be studied in detail. The new FRIB accelerator will give researchers access to more than 1,000 new isotopes, giving them new insight into cancer According to scientists from MSU.

“The FRIB will be a core part of our nation’s research infrastructure,” said Thomas Glasmacher, Director of the FRIB Laboratory, at the ribbon-cutting ceremony. Lansing State Magazine. “More than 1,600 scientists are eager to come here because we will be the best, most powerful superconducting heavy ion linear accelerator.”
Physicists are excited about FRIB because it can provide a much clearer view of the context of possible atomic isotopes. Right now, physicists have a good idea of what holds nuclei together – one of the four fundamental forces known as the strong force – and have created some good models to predict some What an unobserved atomic nucleus might look like. But nuclei are complex and can stick together in surprising ways, making models too simplistic. For example, some nuclei predicted by the models may not stick together well enough to survive.
Other questions the scientists hope to answer include how well the most stable isotopes are described in current models, and how elements are heavier than iron and nickel. the latter two are the heaviest elements produced by nuclear fusion in stars) formed through beta radioactive decay. Beta decay occurs when the nucleus of an atom absorbs a neutron or when one of its neutrons becomes a proton, rendering the nucleus unstable.
Scientists believe that elements formed by beta decay are often produced as by-products of supernovas or the collisions of neutron stars, but until now it has not been possible to test or study the type. which elements are produced and in what proportions in these celestial processes. . But the FRIB will provide one final way to test these hypotheses, like one if its accelerators accelerate individual isotopes before slamming them into a target, allowing scientists to model simulate the collisions that take place inside stars and supernovas.
To produce isotopes for research, physicists will select atoms of a very heavy element, such as uranium, before stripping them of their electrons to turn them into ions. They will then launch them down a 1,476-foot (450-meter) pipe more than half the speed of light. At the end of the pipeline, the ion beam will strike a graphite wheel, crumbling into smaller neutron-proton combinations, or isotopes.
By manipulating these newly created isotopes through a series of finely tuned magnets, physicists will be able to carefully select the isotope they want to shoot into one of the facility’s laboratories. for further research. The FRIB will eventually be joined by another atom smasher, the $3.27 billion Facility for Antiproton and Ion Research (FAIR) currently under construction in Darmstadt, Germany. The accelerator, designed to be completed by 2027, has been designed to generate antimatter as well as matter, and will be able to store the nuclei it produces over a longer time frame than the FRIB.
