Pulsed electron beams can be used to cool beams of ions and protons circulating in a hadron storage ring a promising development for future high-energy accelerators.

In hadron accelerators, the accelerated ion or proton beam heats up over time, degrading in quality. A popular method for counteracting beam degradation involves using an electron beam to cool the ions: the electron beam mixes with the hadron beam and cools it down as the two beams travel along the same path. Now, Max Bruker of Thomas Jefferson National Accelerator Facility in Virginia and colleagues have demonstrated an electron cooling technique that works with electron pulses, rather than with continuous electron beams [1]. The bunched scheme will be applicable to future hadron accelerators that are expected to achieve higher particle energies than existing facilities.

UPTON, NY With all the remarkable changes and challenges that took place in 2020, the U.S. Department of Energy’s Brookhaven National Laboratory had a banner year in science. Many Lab employees worked remotely to keep vital science programs running while minimizing the spread of SARS-CoV-2, the virus responsible for the COVID-19 pandemic. And throughout this unprecedented year, dedicated Lab staff collaborated on new ways of working to transform scientific meetings, educational outreach programs, tours, and more to new virtual formats that reached larger audiences than ever before. Among the top stories of 2020, as measured by importance, page views, engagement on social media or all three! are:

HAMPTON UNIVERSITY PRESIDENT DR. WILLIAM R. HARVEY SEALS 43 STELLAR YEARS OF LEADERSHIP BY ANNOUNCING PLANS TO RETIRE IN JUNE 2022
Hampton, VA, Dec. 14, 2020 (GLOBE NEWSWIRE) Dr. William R. Harvey arrived on the campus of Hampton Institute, in 1978, to take over the reigns as leader of an institution that was slowly losing ground. Many wondered why he chose Hampton. Other institutions, including majority institutions and more financially stable institutions, had offered him presidencies, but he decided to accept the position at Hampton. He chose Hampton because he wanted to be in a place where he could offer the greatest service and make a difference. Dr. Harvey has often stated that choosing Hampton was the best professional decision of his life!
