Magnet's last stand

Thanks to the Education Office, FESS and Technical Division, the Lederman Science Center now houses a memento of the Tevatron — a dipole magnet similar to others that steered proton and antiproton beams in the now retired collider.

For years the Education Office has sought a Tevatron magnet to add to the Lederman Science Center collection of particle physics tools. One finally became available late last month — the last display model of a Tevatron magnet. It was previously displayed in the Wilson Hall atrium.

"They could never cobble together another one because there were no parts left," said Marge Bardeen, head of the Education Office.

Although Fermilab's vast store of magnets includes a number of dipole magnets, none were exhibit-ready. Most of the educational value of an accelerator magnet is on the inside, so display magnets are cut open and peeled back to expose the intricacies beneath the shell. This disassembly is a complex and costly process, so rather than calling up a new magnet to be surgically cracked open, the Education Office inherited an existing display model.

Technical Division's Sean Johnson refurbished the display magnet and built a frame to support it. He planned the move of the magnet for the afternoon of Friday, Aug. 8, when the center was closed and no members of the public were present.

With the help of a crane, Johnson and four staff members from the Technical Division and FESS loaded it on to a truck at the Industrial Center Building and drove it to the science center. They again used a crane to remove it from the truck onto a dolly. After rolling it into its new home, they used an engine hoist to lift the magnet and put on its pedestal.

"They'd planned it through twice," said Marge Bardeen, head of the Education Office. "It was quite exciting."

Now visitors to Lederman Science Center can have an up-close look at a piece of Fermilab's proud history.

In Brief

Louise LeBourgeois talks about her work - tomorrow at noon in Fermilab Art Gallery

An art talk on the current Fermilab Art Gallery exhibit takes place tomorrow at noon.

On Wednesday, Sept. 3, artist Louise LeBourgeois will give a talk on her exhibit at the Fermilab Art Gallery. The talk takes place at noon.

LeBourgeois explores her relationship with Lake Michigan in much of her artwork. Having spent summers swimming in open water, she will discuss the relationship between her painting and her swimming: the interaction between her own body in with a large body of water and the metaphysical implications of pushing off from solid ground and moving through fluid space.

Quark quartet fuels quantum feud

From Quanta Magazine, Aug. 27, 2014

In August 2003, an experiment at the KEKB particle accelerator in Japan found hints of an unexpected particle: A composite of elementary building blocks called quarks, it contained not two quarks like mesons or three like the protons and neutrons that constitute all visible matter, but four — a number that theoretical physicists had come to think the laws of nature did not permit. This candidate "tetraquark" disintegrated so quickly that it seemed a stretch to call it a particle at all. But as similar formations appeared in experiments around the world, they incited a fierce debate among experts about the correct picture of matter at the quantum scale.

Director's Corner

The road to the top

Fermilab Director
Nigel Lockyer

Fermilab is poised to host a world-leading accelerator-based neutrino program and to deliver on several key laboratory initiatives such as PIP-II, muon and cosmic experiments and new particle searches at the LHC. One of the ways we can ensure our success is to focus on working smarter.

Over the past several years, Fermilab introduced and implemented the human performance improvement (HPI) process in many key areas of the lab to improve efficiency, productivity, quality and safety. In areas of the lab where this philosophy has been embraced, we have seen marked improvements in work efficiency, staff morale and reduction in injury rates and injury severity.

Both a proven and powerful tool, HPI reminds us to take a step back, look at the big picture and make fundamental improvements in processes — and to work smarter. HPI shows us how to minimize the frequency and severity of incidents that result in unwanted outcomes. What are unwanted outcomes? They could be a bad product, a poor quality result, an inefficient work area, injury to a worker, damage to equipment or damage to the organization.

When we work smarter, we can spend more time focusing on the important scientific work that we do — and move closer to achieving our mission.

It's time to expand HPI so we can realize improvements in all areas of the organization.

To fully integrate HPI labwide, all managers and employees will be requested to take either a two-day manager course or a half-day employee course. This is an opportunity to learn a philosophy and equip yourselves with the tools to engage your coworkers and help to make your group, department or division better, more efficient, safer – and smarter. HPI courses will be added to the Individual Training Needs Assessments map and included in each employee's training plan. Both manager and employee classes will be offered every six months until we have reached our goal to educate everyone on the value of HPI.

The expanding universe: dark energy

From The Physics Teacher, September 2014

Editor's note: Fermilab scientists Don Lincoln and Brian Nord wrote this article.

As is true of a far more famous story, it all began a long time ago, in a galaxy far, far away. It even involved a binary star system. A small star, called a white dwarf, had become a burned out husk of its former self and it turned to gorging on hydrogen and helium from its bloated red giant neighbor. The transferred gas reignited the fires of the white dwarf until the temperature from the fusion reaction proved too much for the gravity that struggled to contain it. In the blink of an eye, the star detonated in a supernova, a cosmic maelstrom seen perhaps only once per century in a typical galaxy.
