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.
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.
Fermilab scientist Jonathan Jarvis hunts for the pieces of obscure hardware needed to get the OSC experiment going. His late-night, last-minute scouting expedition takes place in the final minutes before IOTA saw first beam in December.
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 shows the octupole channel in the Fermilab Integrable Optics Test Accelerator, or IOTA, in November. A set of 17 independently powered octupole magnets is installed in one of the straight sections of IOTA. The channel is used for experiments on nonlinear integrable optics and on the physics of dynamical systems. These experiments study new ways to stabilize high-intensity beams for research at the frontiers of particle physics.
