Ben Lee Fellow Sally Dawson speaks today at colloquium

Sally Dawson of Brookhaven National Laboratory, the current Ben Lee fellow in the Fermilab Theory Department, will present this afternoon's colloquium, "What Is the Energy Scale Beyond 1 TeV?"

Much in demand as a lecturer at conferences and summer schools around the world and co-author of the celebrated "Higgs Hunter's Guide," Sally will focus on the importance of understanding the properties of the Higgs boson, specifically its couplings to fermions and gauge bosons. She will consider, in the context of various conjectures for new physics at high-energy scales, how well we need to measure the Higgs-boson couplings.

After receiving her Ph.D. from Harvard in 1981, Sally began her career as a Fermilab postdoc. While here, she co-authored influential articles on the search for supersymmetric particles and on the production of heavy quarks in hadron-hadron collisions. During a second postdoctoral appointment at Lawrence Berkeley National Laboratory, she helped uncover the importance of vector boson fusion for Higgs boson production.

She moved in 1986 to Brookhaven, where she has made many notable contributions to the phenomenology of electroweak symmetry breaking and the search for phenomena beyond the Standard Model, including numerous calculations important for the interpretation of data from the Tevatron and Large Hadron Collider.

Dawson has led the Brookhaven theory group and chaired the Physics Department. She now serves as adjunct professor at Stony Brook University. Her extensive community service includes chairing the Fermilab Physics Advisory Committee and the Division of Particles and Fields of the American Physical Society, as well as serving as vice chair of the EPP2010 committee of the National Research Council. She is a fellow of the APS and the American Association for the Advancement of Science.

The Ben Lee Fellowship, successor to the Fermilab Frontier Fellows program, brings distinguished senior theorists to Fermilab to contribute to and profit from the intellectual life of the laboratory. The fellowship honors the memory of Benjamin W. Lee, one of the world's leading theorists, who led the theory group from 1973 until his tragic death in an auto accident in 1977.

Rolling for Rutherford

A local student conducts the Rolling for Rutherford experiment at Sunday's Fermilab Family Open House. In 1909, Ernest Rutherford conducted an experiment that led him to determine that an atom's nucleus was a tiny volume compared to the size of the entire atom. He aimed alpha particles (two protons and two neutrons) at a metal foil and observed the patterns made by the recoiling alpha particles. At the open house, children conducted a larger-scale version of this indirect measurement: They determined the radius of a ball by rolling a "probe" ball (Rutherford's alpha particle) at a row of hidden "target" balls (Rutherford's metal foil), counting the number of times the probe collides with the target. Inputting their data into the appropriate equation, they got excellent experimental results: The calculated value of the ball's radius was 1.39 centimeters, with a deviation of a mere 0.7 percent from the measured value of 1.4 centimeters.

Fermilab's neutrino detector sees its first particles

From Popular Science, Feb. 11, 2014

They've traveled 500 miles underground, passing through soil and rock as easily as Casper the Friendly Ghost glides through walls. They've gone straight through the Earth, reaching their destination without needing any guidance — no tunnels, no cables — along the way. What are these little ghosts? They're neutrinos, particles scientists created at the Fermi National Accelerator Laboratory near Chicago and then aimed at a 14,000-ton detector located in Ash River, Minnesota, near the Canadian border. Fermilab announced today it saw its first neutrinos arriving at Ash River.

Hot, and cold, topics at Fermi's Family Open House

From The Beacon-News, Feb. 9, 2014

Budding scientists didn't exactly need a cryogenic expert to explain the effects of this winter's freezing temperatures.

"It doesn't take long for your fingers to tingle," said Justine Frerrer, 13.

On Sunday, inquisitive kids and their families attended a Family Open House at Fermi National Accelerator Laboratory in Batavia, an annual event that opens the door to the world of physics.

The NIU-Fermilab connection in accelerator science

Philippe Piot

Philippe Piot, professor of physics at Northern Illinois University and Fermilab staff scientist, wrote this column.

Northern Illinois University and Fermilab have enjoyed a strong relationship in accelerator science for a long time. Fermilab operates state-of-the-art accelerator facilities that provide valuable hands-on experience and research opportunities for students from NIU. The laboratory also has many world-expert accelerator scientists, engineers and technicians who share their savoir-faire on a daily basis and help educate students across a broad range of disciplines including beam physics, laser science, high-power radio-frequency to ultra-high vacuum techniques.

The accelerator science program at NIU was initiated a decade ago via joint appointments of scientists, who then work for both institutions. The symbiosis between the two institutions has led to the graduation of three Ph.D. students in the NIU accelerator science program based on research performed at Fermilab over the last three years.

The Advanced Superconducting Test Accelerator, currently under construction at Fermilab, will further this collaboration and foster new initiatives. NIU recently graduated the first student, Christopher Prokop, with research pertaining to ASTA. Three other NIU students are currently doing research at ASTA, investigating beam-driven wakefield acceleration, novel compact radiation sources and advanced phase-space manipulations.

Access to Fermilab's facilities undoubtedly has elevated NIU's profile and helps attract new students interested in accelerator science. It also has helped NIU attract extramural funding from the Department of Energy, the Department of Defense and industry.

NIU President Douglas Baker, who assumed his position last summer, already has visited Fermilab twice and was impressed by the opportunities available to our students and faculty. He recently said that he is considering adding an NIU faculty position in accelerator science during the next few years, as NIU intends to be a major academic partner in the Illinois Accelerator Research Center.

IARC Director Bob Kephart recently visited NIU to discuss potential opportunities for collaboration. One avenue currently being pursued is NIU's involvement in moving the AZero photoinjector at Fermilab to the IARC building in support of the development of high-current electron sources and accelerator-based compact light sources.

The NIU-Fermilab connection creates benefits beyond the state of Illinois. It advances basic research, accelerator R&D, education and industry. NIU is glad to be a part of this partnership.

Safety Update

ESH&Q weekly report, Feb. 11

This week's safety report, compiled by the Fermilab ESH&Q Section, contains two incidents.

An employee slipped and twisted her foot, causing her to fall on her knee. She received first-aid treatment.

A supervisor accidentally entered the NuMI pre-target and target hall without the correct keys. He self-reported the controlled-access violation.
