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.
The optical stochastic cooling experiment’s undulator magnet installed in the Fermilab Integrable Optics Test Accelerator, or IOTA, in November.
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.
Nikita Kuklev, graduate student at the University of Chicago, and Alexander Valishev, scientist at Fermilab and head of the Accelerator Science and Technology Sector in the Accelerator Division, collect the last data sets before the end of Run 2 at the Fermilab Integrable Optics Test Accelerator, known as IOTA, in March (while keeping their distance from each other). During this research period, several experiments were carried out, including studies of new magnet configurations to stabilize high-intensity beams for future particle physics experiments.
Evan Angelico, graduate student at the University of Chicago, sets up the time-of-flight experiment (T-1553) at the Fermilab Test Beam Facility. The experiment studies techniques to identify high-energy particles based on their velocity by measuring their positions and arrival times with novel large-area picosecond photodetectors, known as LAPPDs.
Some interns have already finished their work at the lab, and others are here for a bit longer. It would be very nice to see them again next year.
After the first electron beam was circulated in August 2018, the experimental program at the Fermilab Integrable Optics Test Accelerator (IOTA) continues with commissioning of machine and diagnostics and with the first beam-physics experiments.
A stunning, rainbowed sky sweeps over Site 67, as seen from the NML building, after a thunderstorm on Sept. 25.
This work, “Dark Matters,” is a concept/sculpture by Jim Jenkins, 2017 Fermilab artist-in-residence. The center of the sculpture is a lead-glass block from the electromagnetic calorimeter of Fermilab experiment E-760/E-835 (charmonium spectroscopy). This picture was taken after a performance of “Quatuor pour la Fin du Temps” by Olivier Messiaen in Ramsey Auditorium. The sculpture was positioned behind the performers on the auditorium stage.
