Special Announcement

All-hands celebration of Muon g-2 and MicroBooNE - today at 9:30 a.m. in auditorium

You are invited to celebrate the move of the Muon g-2 magnet to its permanent home and the recent successful move of the MicroBooNE detector today at 9:30 a.m. in Ramsey Auditorium.

Muon g-2 Project Manager Chris Polly, MicroBooNE Deputy Project Manager Catherine James and MicroBooNE Co-Construction Manager Jennifer Raaf will discuss the projects.

Afterward enjoy refreshments with your colleagues in the atrium and talk with scientists about the experiments.

In-person participation is encouraged. The meeting will not be videostreamed.

A whole-Earth approach

Each summer for the past 25 years, ecologist John Harte has spent his mornings in a meadow on the western slope of the Rocky Mountains. He takes soil samples from a series of experimentally heated plots at the Rocky Mountain Biological Laboratory, using the resulting data to predict how responses of ecosystems to climate change will generate further heating of the climate.

Harte, a former theoretical physicist, studies ecological theory and the relationship between climates and ecosystems. He holds a joint professorship at UC Berkeley's Energy Resources Group and the university's Ecosystem Sciences Division. He says he is motivated by a desire to help save the planet and to solve complex ecological problems.

"John is a gifted naturalist and a great birdwatcher," says Robert Socolow, a colleague and former physicist who transitioned to the environmental field at the same time. "John went into physics to combine his deep love of nature and his talent for mathematical analysis."

Harte, who loved bird watching and nature as a child, also enjoyed physics and math, which his schoolteachers urged him to pursue. He received his undergraduate degree in physics from Harvard in 1961, and a PhD in theoretical physics from the University of Wisconsin in 1965. He went on to serve as an NSF Postdoctoral Fellow at CERN from 1965-66 and a postdoctoral fellow at Lawrence Berkeley National Laboratory from 1966-68.

It was in the storied summer of 1969 while Harte was teaching physics at Yale that he decided to return to nature studies. He and Socolow spent a month that summer conducting a hydrology study of the Florida Everglades, and their work showed that a proposed new airport would endanger the water supply for hundreds of thousands of people. That work, which Harte and Socolow detailed in one chapter of the book Patient Earth, led to the creation of an immense water conservation area in southwestern Florida.

"With not much more than back-of-the-envelope calculations, we were able to stop the jetport," Harte says. "I thought, man, that's cool. I want to do this."

Harte was already worried about climate change and decided to transition to studying interdisciplinary environmental science. He sought out the wisdom of famous ecologists, such as G. Evelyn Hutchinson, to help him learn the field.

"I was lucky because I made this transition in the late '60s and '70s," Harte says. "It was a novelty back then, and there weren't a lot of people doing the things I wanted to do."

He retained his love for physics and used physics concepts in his work.

"Unification is such an important goal in physics," Harte says. "I came away with the thirst for finding unification in ecology. I also came away empowered that I could master practically any mathematic formula."

Spill some oil? Magnetize it for cleanup

From Scientific American, Aug. 17, 2014

Oil and water don't mix. Despite that age-old axiom, it sure is hard to get spilled petroleum out of seawater, as was evident during BP's blowout in the Gulf of Mexico. But what if you could make oil magnetic?

That thought came to physicist Arden Warner while he watched coverage of the spill back in 2010. And it launched some garage tinkering for Warner, who by day works on improving particle accelerators at Fermilab.

He shaved iron bits from a shovel and sprinkled them atop some engine oil. Lo and behold, a refrigerator magnet pulled the blob of oil wherever he wanted. Now he's got a patent on the concept that he's refined over the past few years.

From the Accelerator Physics Center

The Tevatron experience

Valeri Lebedev
Vladimir Shiltsev

Valeri Lebedev, assistant head of the Accelerator Division, and Vladimir Shiltsev, director of the Accelerator Physics Center, wrote this column.

In about a month we will pass the third anniversary since the shutdown of the Tevatron collider. For many of us, the Tevatron era will always be remembered for the enthusiasm of the troops, the importance of the collider program and the many ups and downs on the way to its ultimate success — and also because we were much younger then.

As for the scientific outcome of the Tevatron, it is well reflected in less emotional papers, books and reviews. A new book, titled "Accelerator Physics at the Tevatron Collider," features articles written by a team of 20 accelerator physicists.

The book presents major advances in accelerator physics and technology implemented at the Tevatron proton-antiproton collider during its decades-long quest for better and better performance. The collider was arguably one of the most complex research instruments ever to reach the operation stage and is widely recognized for many technological breakthroughs and numerous physics discoveries. The articles in the book describe the contributions to the physics of colliding beams made to maximize the Tevatron luminosity, including novel beam optics methods, accelerator magnets and magnetic field effects on beam dynamics, advanced longitudinal beam manipulation methods widely used in the Main Injector and Recycler, high-intensity beam issues and instabilities, beam emittance growth and halo collimation, production and cooling of antiprotons, the beam-beam effects, and beam diagnostics.

We dedicated this book to Fermilab staff, who made possible the Tevatron — the particle accelerator that shaped the world's high-energy physics landscape for more than quarter of century.
