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.
Jonathan Jarvis and Jamie Santucci install the apparatus for the new optical stochastic cooling experiment in the Fermilab Integrable Optics Test Accelerator, known as IOTA, in November. The experiment uses infrared light emitted by electrons in an undulator magnet to sense and to adjust their positions and velocities. The goal is to demonstrate for the first time a significant increase in the density and therefore in the quality of charged particle beams using this principle.
From University of Wisconsin-Madison, Sept. 28, 2020: Getting blasted with proton beams takes a toll on accelerator targets. As researchers begin to consider upgrading existing accelerators and building more powerful models, the durability of those devices is a major concern. University scientists are working with Fermilab in a new collaboration to study and improve the durability of targets and target windows, which will be important for neutrino experiments such as the international Deep Underground Neutrino Experiment, hosted by Fermilab.
Fermilab and partners in northern Illinois have established the region as a leader in particle accelerator science and technology. Few places in the world boast such a concentrated effort in particle acceleration research, developing and building cutting-edge particle accelerators, and growing an accelerator-focused workforce.
