Safety recognition celebration

On Sept. 1, contractor Barton Marlow and their subcontractors celebrated an exemplary safety record for their work on the Cryomodule Test Facility (CMTF) construction project. Between this project, which involved the construction of two buildings to house a new cryogenic plant and multiple SRF test stands, and the New Muon Lab expansion project, the contractors worked over 40,000 man hours without a recorded lost-time accident. The projects were funded by the American Recovery Reinvestment Act. Photo: Reidar Hahn

A final smash for America's giant particle collider

From NPR Morning Edition, Sept. 6, 2011

A physicist named Dmitri Denisov walks up wooden steps to the top of something that looks sort of like an abandoned railroad bed.

"Wow, look, it's beautiful," Denisov says, gazing out at a pond. "I didn't even know about these flowers."

The tall mound of dirt he's standing on stretches off into the distance, forming a huge circle nearly four miles around — and the inside of this ring is filled with acres of restored prairie.

"The first time I came here was 1989," recalls Denisov. At the time, he was a young scientist from the Soviet Union. "I remember sort of coming to this point and looking and saying, 'Wow, that's really a big machine!'"

The machine, which Denisov is standing on, is called the Tevatron. Beneath this earthen berm is a tunnel that serves as a high-tech racetrack for protons and anti-protons. They accelerate to almost the speed of light, and then slam together in collisions that spew out the hidden particles that make up matter.

The Tevatron has been the pride of the Fermi National Accelerator Laboratory, near Chicago, for a quarter of a century. But at the end of this month, the Tevatron is shutting down.

It's no longer the most powerful machine in the world for smashing bits of atoms together so that scientists can search through the sub-atomic rubble.

Astrophysicists report first simulation to create a Milky Way-like galaxy

From the Unversity of Santa Cruz's newsroom, Aug. 29, 2011

Supercomputer experiment supports cosmological model of a "cold dark matter" universe

After nine months of number-crunching on a powerful supercomputer, a beautiful spiral galaxy matching our own Milky Way emerged from a computer simulation of the physics involved in galaxy formation and evolution. The simulation by researchers at the University of California, Santa Cruz, and the Institute for Theoretical Physics in Zurich solves a longstanding problem that had led some to question the prevailing cosmological model of the universe.

"Previous efforts to form a massive disk galaxy like the Milky Way had failed, because the simulated galaxies ended up with huge central bulges compared to the size of the disk," said Javiera Guedes, who recently earned her Ph.D. in astronomy and astrophysics at UC Santa Cruz and is first author of a paper on the new simulation, called "Eris." The paper has been accepted for publication in the Astrophysical Journal.

The Eris galaxy is a massive spiral galaxy with a central "bar" of bright stars and other structural properties consistent with galaxies like the Milky Way. Its brightness profile, bulge-to-disk ratio, stellar content, and other key features are all within the range of observations of the Milky Way and other galaxies of the same type.

Director's Corner

End of summer

Fermilab Director Pier Oddone

Yesterday we celebrated Labor Day and the end of summer. Celebrating labor is easy - we have done a prodigious amount of it in the last few months, and we see nothing but a huge amount ahead of us.

It has been a good but arduous summer, with a series of Tevatron problems associated with storms and with a number of difficulties with the NuMI neutrino targets. The Tevatron is back up to snuff with more than 60 inverse picobarns for the last week, and we are running the neutrino beams very effectively with one of the previously used targets. The Tevatron is approaching 2.5 inverse femtobarns for the year, while the NuMI beam has delivered more than 2x1020 protons on target and the Booster neutrino beam delivered more than 3x1020 protons on target. One important accomplishment during the last few months, among many others, was to give enough data to the MINOS collaboration to settle the previously observed differences between neutrino and antineutrino oscillations. The additional data fluctuated in the opposite direction to that previously measured by the collaboration and tells us that, within statistical accuracy, neutrino and antineutrino long-baseline oscillations behave the same.

The collider collaborations have also been working night and day. For the Tevatron, the urgency is to get results out as quickly as possible, since in many areas the Tevatron is being surpassed by the LHC. The LHC collaborations have been working around the clock and around the world to analyze the rapidly increasing data sets. The performance of the detectors and the ability to perform rapid analysis of LHC data is most impressive. The Higgs has been cornered to below 145 GeV and a host of models for new physics have been ruled out as the data so far is spot-on in agreement with the Standard Model. For many physicists the biggest surprise so far is that discovering new physics at the LHC will not be as easy as rolling off a log, as many had originally predicted. We are fortunate that the data sample will eventually be a factor of a thousand greater than what is collected so far and so there is ample room for new discoveries and surprises.

Of course there are many other accomplishments in our physics programs. All of these physics accomplishments, which are our ultimate product, would not be possible without the great dedication and prodigious labor of our colleagues in the many facets of laboratory operations that sustain our productivity. We do not sing the praises of this work often enough because we tend to focus on our goal of physics results. Labor Day was a good day to celebrate the devotion and generosity of everyone who labors at Fermilab to make our “mission impossible” possible.
