From Advanced Science News, August 19, 2022: A team of researchers led by Fermilab’s Jonathan Jarvis have successfully demonstrated optical stochastic cooling. This improved technique will increase the achievable cooling rate by up to four orders of magnitude and ultimately allowing physicists to spend more time collecting experimental data.

From Techfragments, August 12, 2022: Jonathan Jarvis led a team of researchers who used the Integrable Optics Test Accelerator at Fermilab to demonstrate and explore a new kind of beam cooling technology. “Cooling” a beam reduces the random motion of the particles making the beam narrower and denser. Physicists could potentially use this new method to explore rare physics phenomena that help us understand our universe.
Scientists successfully used a new technique to cool a particle beam and make it denser. The new method may enable future experiments to create more particle collisions. Denser particle beams provide researchers a better chance of exploring rare physics phenomena that help us understand our universe.
Ihar Lobach, a former student in the Fermilab Accelerator Ph.D. Program, is the recipient of the American Physical Society’s 2022 Outstanding Doctoral Thesis Research in Beam Physics Award. He was recognized for outstanding research contributions as well as for developing an experimental method.
Fermilab user and University of Chicago PhD candidate Ihar Lobach explains how his team used Fermilab’s IOTA electron storage ring to glean insights that can be difficult to obtain on an electron beam and how this proof of principle could benefit the Advanced Photon Source Upgrade at Argonne National Laboratory.
High-intensity particle beams enable researchers to probe rare physics phenomena. A proposed technique called optical stochastic cooling could achieve brighter beams 10,000 times faster than current technology allows. A proof-of-principle experiment to demonstrate OSC has begun at Fermilab’s Integrable Optics Test Accelerator.
This award, totaling $2.5 million, will fund the development of a faster particle beam cooling method as well as the implementation of machine learning advancements to optimally control the system.
Fermilab researchers have announced first results from IOTA, the lab’s newest particle accelerator. The first run, which included observations of single electrons circulating in the ring, illustrates the exciting potential of the versatile machine, both in advancing quantum science and improving accelerator beams.
From CERN Courier, Oct. 29, 2018: In late August, a beam of electrons successfully circulated for the first time through a new particle accelerator at Fermilab. The Integrable Optics Test Accelerator, a 40-meter-circumference storage ring, is one of only a handful of facilities worldwide dedicated to beam-physics studies.
IOTA, the new test accelerator, gives researchers rich and varied opportunities to dive deep into the physics of particle beams.
