Hahn shot first

Reidar Hahn

After 32 years as Fermilab’s staff photographer, Reidar Hahn is retiring – and saying farewell with a final collection of photos in Fermilab’s art gallery. The exhibit will run from Nov. 6, 2019, to Jan. 3, 2020, with a free artist’s reception on Nov. 8.

Kirsty Duffy, a Lederman fellow at Fermilab, says neutrinos are the most interesting particles in the universe. As a recipient of the Leona Woods Distinguished Postdoctoral Lectureship Award, she’ll have a chance to make her case in two talks she’ll deliver at the Brookhaven National Laboratory this November.

Berkeley Lab’s Dark Energy Spectroscopic Instrument aimed its robotic array of 5,000 fiber-optic “eyes” at the night sky Oct. 22 to capture the first images showing its unique view of galaxy light. It was the first test DESI with its nearly complete complement of components. Fermilab contributed key elements to DESI, including the corrector barrel, hexapod, cage and CCDs. Fermilab also provided the online databases used for data acquisition and the software for the instrument’s robotic positioners.

What keeps galaxies from flying apart? What is the invisible mass that bends light in space? For now, we’re calling it dark matter, and this Oct. 31, laboratories around the world are shining a light on the search for it. Dark Matter Day events include live webcasts with researchers, dark matter scavenger hunts and a Reddit AMA.

In their ongoing search for the mysterious dark matter that makes up 85% of our universe, the particle physics community turns its sights to particles of low mass. The Department of Energy announced that it is providing funding for two Fermilab initiatives to develop experimental designs for experiments that will be highly sensitive to the smallest particles of dark matter. Following the development of the experimental designs, the next phase of funding will be subject to additional reviews and approval.

On Thursday, Oct. 17, from approximately 9 p.m. to midnight, Fermilab and the Kane County Sheriff’s Office will conduct live-gunfire tests of Fermilab’s on-site gunfire detection system. These tests will be conducted safely, using bullet traps – no live rounds will be fired into the air or into the ground, and there will be no danger to the public or wildlife. However, the sound of gunfire may be heard in neighborhoods near Fermilab on Thursday evening.

Advances in subatomic physics heavily depend on ingenuity and technology. And when it comes to discovering the nature of some of the most elusive particles in the universe, neutrinos, scientists need the best and most sensitive detector technology possible. Scientists working at CERN have started tests of a new neutrino detector prototype, using a very promising technology called “dual phase.”
