The PIP-II project at Fermilab includes the construction of a 215-meter-long particle accelerator that will accelerate particles to 84% of the speed of light. Research institutions in France, India, Italy, Poland, the UK and the United States are building major components of the new machine. The new particle accelerator will enable Fermilab to generate an unprecedented stream of neutrinos — subtle, subatomic particles that could hold the key to understanding the universe’s evolution.

From The Innovation Platform, June 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 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.

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.
