Sergei Nagaitsev takes over as head of Accelerator Division

Sergei Nagaitsev

On Dec. 1, Sergei Nagaitsev stepped into his new role as head of the Accelerator Division. He succeeds Roger Dixon, who led the division for almost 11 years. Dixon will stay on in an advisory role for a limited period.

He says Nagaitsev will be an exceptional leader.

"I have as much or more respect for Sergei and his scientific abilities, particularly in accelerators, than absolutely anyone I've ever known," Dixon said.

Nagaitsev plans to continue the work established under his predecessors while steering the division to support a research home for particle and accelerator physicists around the globe.

"Our vision is to be a laboratory where researchers from this country and the world want to do their experiments," Nagaitsev said. The division's most critical roles, he said, are to keep the accelerators running and to deliver what it promises to experiments such as NOvA and Muon g-2, as well as to outside projects such as the LHC upgrades.

Nagaitsev, an APS fellow, joined Fermilab in 1995 to develop an electron cooling system for the Recycler. He became head of the Recycler Department in 2004, and after six months in the position, rehabilitated the ailing accelerator, which had been experiencing problems for about two years.

"The only mistake he made there was that he said it was going to take longer than it took," Dixon said.

In 2005 Nagaitsev was appointed deputy director for Fermilab's ILC program. He assumed a leadership position in the Project X program in 2011.

"Sergei is well-known, not only inside the lab but internationally, for his many innovations contributing to the performance of Fermilab's accelerators over the last decade," said Associate Director for Accelerators Stuart Henderson. "His work on electron cooling, in particular, led to the amazing luminosity of the Tevatron collider."

Nagaitsev said he looks forward to meeting more of the Accelerator Division's 400 employees, including new faces that have joined since the time he worked as part of accelerator operations. He and Dixon will hold a meeting for all AD employees today to introduce Nagaitsev as AD head and to meet and chat with division members.

"We'll continue to innovate and think outside the box to provide, with our limited resources, various upgrades and capabilities we don't have in the toolkit right now," Nagaitsev said.

"I've been very attached to this division, and I care about it a lot," Dixon said. "I feel very good about leaving it in Sergei's hands."

The future of the Higgs boson

From Physics Today, December 2013

Experimentalists and theorists are still celebrating the Nobel-worthy discovery of the Higgs boson that was announced in July 2012 at CERN's Large Hadron Collider. Now they are working on the profound implications of that discovery.

Symmetries and other regularities of the physical world make science a useful endeavor, yet the world around us is characterized by complex mixtures of regularities with individual differences, as exemplified by the words on this page. The dialectic of simple laws accounting for a complex world was only sharpened with the development of relativity and quantum mechanics and the understanding of the subatomic laws of physics. A mathematical encapsulation of the standard model of particle physics can be written on a cocktail napkin, an economy made possible because the basic phenomena are tightly controlled by powerful symmetry principles, most especially Lorentz and gauge invariance.

Yes, but what are neutrinos for?

From The Boston Globe, Dec. 1, 2013

Twenty-eight flashes of blue light may not seem like much to crow about. But for hundreds of scientists long in their pursuit, witnessing these faint flickers over the last two years has been a cause for celebration, because they mark the arrival of ghostly messengers called neutrinos from the far — and incredibly violent — corners of the universe. Last week, researchers reported in Science that IceCube, a novel observatory made of some 5,000 sensory orbs strung on 86 steel cables and buried more than a mile deep in the Antarctic ice, has been registering about one energetic neutrino originating from beyond our galaxy each month.

Director's Corner

Recognizing accomplishments

Fermilab Director
Nigel Lockyer

With 2013 coming to a close, I'd like to take this opportunity to acknowledge a few of the lab's major accomplishments over the past 12 months. It has been a challenging year for us on many fronts, yet because of your continued focus and determination, Fermilab continues to make considerable progress on key projects and achieve many milestones. I look forward to celebrating the year's achievements with all staff and users at Friday's labwide party, starting at 4:30 p.m. in the Wilson Hall atrium.

This week I highlight successes from the accelerator and operations sectors. Achievements from the particle physics and computing sectors will be the focus of my Dec. 17 corner. Congratulations to all of you for the following 2013 accomplishments:

  • Completing a 15-month shutdown for the reconfiguration of the accelerator complex to support the NOvA experiment, the most substantial reconfiguration of Fermilab's accelerator since the Main Injector was built in the late 1990s.
  • Developing special processes for making better performing superconducting materials that will lead to higher-performance accelerating cavities and higher-field magnets.
  • Pushing ASTA forward through the first photoelectrons from the ASTA injector, holding the first ASTA user's meeting and developing a proposal for presentation to DOE.
  • Launching the Muon Campus program, which will enable the next generation of muon experiments.
  • Continually advancing accelerator physics-related research and development.
  • Completing the 20-year Fermilab Campus Master Plan, which details a state-of-the-art physics laboratory capable of hosting a vibrant, international community of employees and users on a safe, accessible site.
  • Planning, designing and constructing the Liquid-Argon Test Facility, which will house the MicroBooNE experiment.
  • Providing essential day-to-day scientific and mission support operations and substantially reducing injury rates from FY12.

On behalf of senior management, I extend a sincere thank you to everyone at Fermilab. Your dedication and hard work each and every day help make scientific discovery possible.

The early universe

How is it possible to look at the earliest moments of the universe? Physicists have their ways — and what they find out will tell us a lot about how the universe works today and how it will unfold in the future. Image: Sandbox Studio

You may have heard that, when you're looking at a star at night, you're actually looking at light emitted up to tens of millions of years ago. It took the light that long to travel from its birthplace to Earth.

Evidence of our distant past is everywhere. You just have to know where and how to look for it. One of the great missions of particle physics is to trace this evidence back to our beginnings.

"The more we understand our origins, the more we understand ourselves and our place in the cosmos," says theorist Michael Ramsey-Musolf, director of the Amherst Center for Fundamental Interactions at the University of Massachusetts.

Scientists have used experiments and observations to investigate our past as far back as a second after the big bang. At that point, the starstuff that makes up everything around us began to materialize. But what happened before that decided the character of the universe today — and may even foretell how it someday will end.

Particle physicists are working to find out exactly what happened in that very first second.

Construction Update

MicroBooNE moves into Phase 1

The MicroBooNE project has received approval to operate Phase 1 and is making final preparations to cool down. Phase 1 includes the purification filters and pumps for removing contaminants from liquid argon to the low parts-per-billion level. A high-voltage test cryostat is a new device installed at the Liquid-Argon Test Facility and will allow detailed measurements of the ability of liquid argon to hold large voltages at varying purity levels and different geometries of electrodes in a large-scale system.
