Debbie Harris named as new MINERvA co-spokesperson

Fermilab scientist Debbie Harris stands in front of the nearly completed MINERvA neutrino detector. Harris was recently elected MINERvA co-spokesperson and will begin the transition to this role in January.

If you told Debbie Harris a decade ago that she'd really enjoy coordinating all of the pieces of an experiment, she would have laughed.

"But I love coordinating all the pieces, no matter how modular they seem," Harris said.

Soon, she'll get to do even more of what she loves.

 Fermilab scientist Jorge Morfin, a MINERvA co-spokesperson for the past six years, will step down from the position in February.

Harris, who has worked on MINERvA since its inception, was recently elected the experiment's new co-spokesperson. She will begin transitioning into the role, currently held by Jorge Morfin, beginning in January. She will work with current co-spokesperson Kevin McFarland of the University of Rochester.

"What we need in a co-spokesperson is someone with a good vision of the experiment's physics goals, and we need someone who can keep harmony within the collaboration and keep the collaboration structured and enthusiastic, even when we start talking about the little nuts and bolts problems," Morfin said. "Debbie will be a great co-spokesperson."

Morfin, co-spokesperson for the past six years, decided not to run for election again so that he can focus on other areas. In addition to working on MINERvA physics, he wants to continue expanding the laboratory's Latin American program and work on the near detector physics and technology for both the Homestake mine and Neutrino Factory projects to encourage the sharing of common efforts.

"I've seen what was a concept 10 years ago develop into an approved experiment and then get backed by the Department of Energy. When I step down, we will have completed building our detector and will be taking data," Morfin said. "I can now get more involved in working on actual physics results."

The end of MINERvA detector construction, expected by the end of January, is a good time for Harris, project manager for MINERvA, to transition, too.

"It is sort of like parenting. If I'm successful, MINERvA won't need a project manager after January or February," Harris said. "This is an honor, a huge honor, and I will have big shoes to fill."

Humanitarian photographer presenting today in One West

Humanitarian photographer Ivan Yee-Gwan Lo will give a presentation today on his work, which documents everyday life, medical programs and education in the developing world. His presentation will take place from 12:15 to 1 p.m. in One West.

Lo, who grew up in Chicago, has photographed for humanitarian non-governmental organizations in Afghanistan, Kenya, the Dominican Republic and Taiwan. The event is part of the Diversity Council's series of events for Universal Human Rights month.

From symmetry breaking

How a new muon experiment can advance physics

In recent years, particle physicists have increasingly turned their attention to finding physics beyond the Standard Model description of the building blocks of matter and how they interact.

While many signs point to the existence of physics outside of the realm of current knowledge, a treasure map doesn't exist, and a new particle's discovery won't necessarily include clues to how it fits into the rest of the particle zoo. Many theories exist to explain the origins of suspected "new physics" and extensions to the Standard Model, the current theoretical framework.

A new Fermilab-based experiment, the Muon-to-Electron Conversion experiment, or Mu2e, could shine light on those gray areas, aiding researchers at the Large Hadron Collider in Europe and likely the next-generation of collider experiments.

A banner year for CDF results

The figure shows the number of papers published in refereed journals per year by the CDF experiment.  With 57 papers already published in FY2009, CDF closes in on an incredible 500 publications during its lifetime.

There were far too many outstanding new results from the CDF collaboration this year to pick just one. With 57 papers published already this year and more than 100 new results presented at international conferences, CDF scientists have had their most productive year to date.

The Tevatron accelerator ran great in 2009. Scientists at CDF now have more than 6 inverse femtobarns of data on tape that can be used for physics analysis.

This staggering amount of data is the result of the accelerator's banner performance and the hard work of the CDF data acquisition and processing groups.

During FY2009, CDF collected and processed about 2 billion data events and more than 1.1 billion simulated events (to model the new data). Just to process these events required more than 100 CPU-years. This means if only one computer processed this information, it would take that machine more than 100 years to finish processing. Archiving these events required well over 1 peta byte of storage space. To put a peta byte into perspective, it is about the combined size of the hard drives of 10,000 personal computers.

Scientists at CDF were able to sort through all the new data to produce many exciting results: For the first time they observed the Omega B baryon and found evidence for the Y4140; scientists performed numerous searches of exotic new particles, resulting in limits on the theories that predict these new particles (for example b', GMSB, and heavy particles decaying to two bosons); they measured Standard Model properties such as the photon cross section, diffractive W production, and the charged particle multiplicity in min bias events; they measured properties of the top quark such as its mass and production rate with better precision than ever before; last but not least, the observation of single top production and two new diboson final states prove that CDF scientists are closing in on the Higgs boson. With the LHC turning on and more Tevatron data arriving daily, there is bound to be even more excitement in 2010.

Edited by Craig Group

As the CDF data sample grows, CDF scientists climb closer to one of their ultimate goals: helping the Tevatron find some sign of the elusive Higgs boson.

Collider meets its goal for power

From The New York Times, Dec. 10, 2009

Tiny spitfires of energy blossomed under the countryside outside Geneva late Tuesday night, heralding the arrival of a new European particle collider as the biggest, baddest physics machine in the world.

Scientists said that the new Large Hadron Collider, a 17-mile loop underneath the Swiss-French border, had accelerated protons to energies of 1.2 trillion electron volts apiece and then crashed them together, eclipsing a record for collisions held by an American machine, the Tevatron, at the Fermi National Accelerator Laboratory in Illinois.

Officials at CERN, the European Center for Nuclear Research, which built the collider, said that the collisions lasted just a few minutes as a byproduct of testing, and that the Champagne was still on ice in Geneva. But in conjunction with other recent successes, those tiny fireballs displaced American physicists as the leaders in the art of banging subatomic particles together to see what nature is made of.
