Fermilab houses connect
past and future
Andrew McCullough talks to current resident and Fermilab physicist Luciano Ristori about the home, where McCullough's mother lived as a child.
As a child, Andrew McCullough's mom used to drive him through Fermilab and point out a white clapboard house that she grew up in.
Last week, a grown man with two boys of his own, McCullough crossed the home's threshold for the first time.
Italian physicist Luciano Ristori and his wife, Mara, who have lived in the home for five years, welcomed McCullough with a tour and homemade pizza.
The Ristoris were eager to hear about the history of the decades-old structure they consider as much a home as their house in Italy. McCullough wanted to share a bit of his heritage with his current family and learn about how his mother's home plays a role in Fermilab's search for an understanding of the universe.
While McCullough's mother, Mary, was not happy when the laboratory bought out Sunbonnet Farm, he said that growing up nearby he has learned to appreciate the laboratory for its science and environmental preservation.
"It is wonderful to have Fermilab here in Batavia, so there are no hard feelings," he said. McCullough's mother and her brother used to tell Andrew stories of hunting and playing in the woods. He hopes to walk his twin sons on the nature trails through those woods.
The family also talked of attending square dances on what is now Site 38.
"These square dances were a big draw. People came from Wisconsin and Indiana," McCullough said.
Roughly two dozen farm homes were relocated in 1977 from throughout the site to the Village. Today, they house physicists, like Ristori, drawn to Fermilab from across the globe.
McCullough surveyed the home's old wood charm and brick fireplace, asking about Ristori's job as a physicist, while Ristori peppered him with questions about the life before the laboratory.
Ristori, who works on CDF, moved from Naperville to the village as soon as the house became available to be close to colleagues and nature.
"It's nicer," he said.

On a similar quest to see family history, John Komes and his wife, Terry, visited the home of John's uncle Ed Kames during a visit from California last year. The former farm of his similarly-named uncle is now Site 51. Its barns house maintenance instead of farm equipment, but Komes could still recall summer days spent playing on the farm as a child.
DZero's Robert Barger sent in this series of photos of a coyote hunting for food. The photo was taken outside Fermilab's Main Ring, just north of CZero. The coyote was unsuccessful and went away hungry.
Is dark matter made of axions?
Feb. 26, 2008
One of the mysteries of our universe is that of dark energy and matter. Scientists all over the world are attempting to discover what particles make up dark energy and matter. "Axions are one of the particles considered for dark matter," William Wester tells PhysOrg.com. "We were hoping to get a signal proving that they exist with this experiment."
Wester, a scientist at the Fermi National Accelerator Laboratory in Batavia, Illinois, worked closely with Aaron Chou, now at New York University, and a group of scientists from Fermilab and the University of Michigan in Ann Arbor, to design an experiment to test the existence of axion-like particles within a certain range. Their results can be found in Physical Review Letters: "Search for Axionlike Particles Using a Variable-Baseline Photon-Regeneration Technique."
Axions are hypothetical particles that have a small mass in the milli-electronvolt (eV) range, making them 500 million times lighter than an electron. Additionally, an axion should have no spin.
"Normally," Chou points out, "we can only detect these kinds of particles with telescopes, looking out into space. And then it is only an indirect detection." The idea was to create conditions allowing them to detect particles in the milli-eV range during a lab experiment.
"For particles that interact strongly enough for us to detect, there are constraints on where they could exist or not," Chou continues. "For the specific region of our experiment, no one would have thought to look into it without the PVLAS experiment."

An average of 2.5 million collisions occur per second at each interaction point in the Tevatron. With the machine's current performance, CDF receives two potential Higgs events per day, needles in a haystack of particle events. To get more potential needles, the Tevatron smashes more particles.
To handle this increase, CDF physicists upgraded the trigger system, the smart system that makes sure these precious needles don't get lost. A strong and dedicated team of young CDF scientists recently completed three upgrades to the second of three trigger levels. The improvements reduce some of the system's bottlenecks and consist of two upgrades to the tracking system and one to the calorimeter system. The upgraded track triggering, which followed an upgrade to the Level 1 component, uses more of the detector layers in the track reconstruction; in particular, it helps to reduce the number of bad tracks that CDF collects by making 3D track reconstruction available at Level 2 for the first time.
The second tracking upgrade installed an electronics board that provides the tracking information to all other Level 2 components more quickly. The calorimeter upgrade replaces hard-coded logic in custom electronics. Energy measurements from the full calorimeter are now sent to a computer that can reconstruct particle signatures with software algorithms similar to those used in physics analyses.
The new Level 2 triggering system collects less unwanted hay at high luminosity, thus allowing the trigger system to collect more of the interesting needle events. All three upgraded systems were recently commissioned and CDF is now taking data with the improved Level 2 trigger system. The physicists at CDF hope that the new system will make it easier to find that elusive Higgs in the haystack of collisions.
