Today at Berkeley Lab

Ed Lofgren, Pioneering ‘Rad Lab’ Physicist, Dies at 102

Lofgren, who died on Sept. 6, played key roles in many projects throughout the Lab’s history. He was a close associate of E.O. Lawrence, and chief physicist for the development, construction, and operation of the Bevatron. He also served as associate laboratory director, and was the first director of the Accelerator Division. He retired in 1979. More>

In Memoriam: Legendary Lab Physicist Ed Lofgren (1914-2016)

Edward Lofgren (2nd from right), a physicist hired by E.O Lawrence who worked on an early isotope-separating cyclotron, participated in the Manhattan Project, and oversaw the operation of the Bevatron accelerator as its first director when the antiproton was discovered there, died Sept. 5, at the age of 102. A full obit, including memorial service details, will appear in TABL in the coming days.

World’s Most Sensitive Dark Matter Detector Completes Search

LUX collaborators presented the results from the detector’s final 20-month run from October 2014 to May 2016. LUX’s sensitivity far exceeded the original expectations of the experiment. These new limits on dark matter detection will allow scientists to eliminate many potential models for dark matter particles, offering critical guidance for next-generation dark matter experiments.
