From CERN Courier, Nov. 10, 2020: Established 30 years ago with a linear electron-positron collider in mind, the TESLA Technology Collaboration has played a major role in the development of superconducting radio-frequency cavities and related technologies for a wide variety of applications. The first decade of the 21st century saw the TTC broaden its reach, for example, gradually opening to the community working on proton superconducting cavities, such as the half-wave resonator string collaboratively developed at Argonne National Lab and now destined for use in PIP-II at 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.
Fermilab scientist Robert Ainsworth has won a $2.5 million Department of Energy Early Career Research Award to study different ways of ensuring stability in high-intensity proton beams. By studying how certain types of beam instabilities emerge and evolve under different conditions, his team can help sharpen scientists’ methods for correcting them or avoiding them to begin with.
From The Innovation Platform, July 10, 2020: In this Q&A, Mauricio Suarez, Illinois Accelerator Research Center head and Fermilab deputy head of technology development and industry engagements, discusses the development of compact particle accelerators, using accelerators for the environment and in medicine, and commercializing technologies developed for high-energy physics.
From fixing up furniture as a kid to testing particle accelerator components at the lab and woodworking in his garage, Dave Burk has a knack for solving problems with his hands.
From Lawrence Berkeley National Laboratory, June 17, 2020: While COVID-19 risks had led to a temporary halt in fabrication work on high-power superconducting magnets built by a collaboration of three national labs for an upgrade of the world’s largest particle collider at CERN in Europe, researchers at Berkeley Lab are still carrying out some project tasks. Fermilab scientist Giorgio Apollinari, head of the U.S.-based magnet effort for the HL-LHC, is quoted in this piece.
Engineers from five countries are coordinating the design of the large cryomodules that will enable the new PIP-II accelerator at Fermilab to generate protons for the world’s most powerful beam of neutrinos, in support of the international Deep Underground Neutrino Experiment.
Fermilab is currently upgrading its accelerator complex to produce the world’s most powerful beam of high-energy neutrinos. To generate these particles, the accelerators will send an intense beam of protons traveling near the speed of light through a maze of particle accelerator components before passing through metallic “windows” and colliding with a stationary target. Researchers are testing the endurance of windows made of a titanium alloy, exposing samples to high-intensity proton beams to see how well the material will perform.
Accelerator magnets — how do they work? Depending on the number of poles a magnet has, it bends, shapes or shores up the stability of particle beams as they shoot at velocities close to the speed of light. Experts design magnets so they can wield the beam in just the right way to yield the physics they’re after. Here’s your primer on particle accelerator magnets.
From Cold Facts, Sept. 17, 2019: Scientists at Fermilabhave achieved the highest magnetic field strength ever recorded for an accelerator steering magnet, setting a world record of 14.1 teslas, with the magnet cooled to 4.5 kelvin or minus 450 degrees Fahrenheit. Lawrence Berkeley National Laboratory held the previous record of 13.8 teslas, achieved at the same temperature, for 11 years.
