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.

Fermilab user Paul Nienaber died on Oct. 31. Nienaber had a long history at Fermilab, having worked on NuTeV, MiniBooNE and MicroBooNE. He was a champion for students and a regular fixture at the lab during the summer months. Read Paul’s obituary. Please consider sharing a memory of Paul or uploading a photo for his family to see. Condolences may be sent to the following: Nienaber Family, c/o Tony Nienaber, 4561 Winners Circle, Batavia, Ohio 45103 or Paul’s friends and…

From Next Avenue, Oct. 26, 2020: Many older scientists stay on the job for reasons such as greater flexibility to do their work, ongoing funding for research projects and just an inherent love of science. Fermilab scientist emeritus Chris Quigg is one of three impressive researchers featured in this article on scientists over 65.
