DZero invites Fermilab family and the public to tour detector

These Fermilab physicists organize DZero tours led by physicists involved in the DZero experiment. From left: Bill Lee, Stefan Gruenendahl and George Ginther. Rich Blaustein, OC

This fall, the DZero site welcomed its 2,500th visitor since arranged tours began in February 2012. Fermilab physicist and DZero co-spokesperson Dmitri Denisov hopes this milestone will spur on more of the Fermilab community and the public to tour the DZero detector site, where its namesake, the DZero detector, operated from 1992 to 2011 and enabled landmark Tevatron results, including the discovery of the top quark. Scientists continue to analyze the data collected by the DZero detector as well as from the Tevatron's other general-purpose detector, CDF.

"It is a great opportunity for Fermilab employees and for the public to see the wonder of the engineering and the technology that goes into a complex particle accelerator detector," Denisov said. "When people tour here, they feel that it is like a rocket launch. It really makes you say, 'Wow! People can really do such complex, amazing, wonderful things.'"

Fermilab physicist Stefan Gruenendahl organizes the tours with help from his DZero run coordination team colleagues George Ginther and Bill Lee. The tours are led by a team of DZero physicists.

"We think that gives people a more intimate experience, because the people who give the tour really did work on it," Ginther said.

Local high school and college classes, Saturday Morning Physics groups, and Fermilab personnel and their family members have made up the typical tour groups so far.

Tours include stops at the DZero assembly hall, the control room (where the screens replay images captured during DZero detector operation) and the Tevatron tunnel. They culminate in the detector and its collision hall. In the assembly hall area there is a special explanatory display, recently enhanced by 10th grade science teacher Lia Koonce of Chicago's Institute of Health and Sciences Career Academy.

Denisov, Ginther and Gruenendahl all emphasize that visiting the DZero sites gives a good sense of currently operating collider detectors.

"They all have the same scheme: vacuum pipe, tracking detectors, magnet, calorimeter and muon identification," Ginther said. "'The detector you see at DZero operated on the same principles as those that are running at the Large Hadron Collider in CERN and other detectors around the world. There are different choices in technology, but the concepts are exactly the same."

Gruenendahl added that you can get up-close views at DZero.

"They have tours at CMS and ATLAS at CERN, but you can not go into the accelerator and into the collider detector there as you can here," he said.

Those interested in the free tour can visit Education Office Web page on DZero tours.

Fidelity town hall meetings through Friday

Beginning today and through Thursday, Dec. 11., Fidelity will host town hall meetings on retirement savings plans at 10 a.m. and 2 p.m. in One West. On Friday, they will host a meeting at 10 a.m. in the Big Room in the CDF building and at 1 p.m. at the Fermilab daycare building. For more information, see the article on Fidelity meetings in the Dec. 4 issue of Fermilab Today.

Study of big bang's afterglow sheds light on evolution of universe

From Science, Dec. 1, 2014

The leading scientific theory of how the universe evolved has again proved accurate — for some, frustratingly so. The latest study of the afterglow of the big bang — the so-called cosmic microwave background (CMB) radiation — confirms even more precisely the standard model of cosmology, researchers with Europe's Planck spacecraft reported today at a press conference in Ferrara, Italy. That's a victory for the theory, but it leaves researchers with no discrepancies that might point to a deeper understanding.

Dark matter detectives

From Air & Space, December 2014

As Peter Redl and a colleague prepare to enter the clean room that houses the Cryogenic Dark Matter Search detectors, they take the usual precautions. Blue bunny suits? Check. Caps and booties? Check. Electronic gizmos? Left in the office. Bananas? Nowhere in sight. "If you put a banana next to the detectors, the radioactive decay of the potassium will cause about 2,000 events per minute," explains Redl, a postdoctoral researcher at Stanford University. "So we're not allowed to eat bananas." When you're searching for the most bashful of cosmic particles, you can't be too careful.

Tip of the Week: Safety

Before and after you turn those keys, look 360 degrees

Remember to look behind you when backing your vehicle. Photo: Fermilab Security

Although we at Fermilab ended fiscal year 2014 with a lower accident rate than in 2013, we still didn't reach goal zero, with backing accidents accounting for 50 percent of all vehicle accidents for the past year. While most vehicle accidents at Fermilab involved only property damage, bodily injuries have been recorded in the past.

According to the National Safety Council, one out of four vehicle accidents can be blamed on poor backing techniques. Backing accidents cause 500 deaths and 15,000 injuries per year in the United States. Here are a few safe vehicle backing tips to help prevent accidents on and off the job.

  • Get to know a vehicle's blind spots. In a medium-size truck, blind spots can extend tens of feet in front of and behind the vehicle. Mirrors can never give the whole picture while backing.
  • Park defensively. Drivers should choose easy-exit parking spaces that don't crowd neighboring vehicles, parking their vehicle in the center of the parking space if possible.
  • Do a 360-degree walk-around. Walking around a vehicle gives the driver a first-hand view of the backing area and any limitations. Check for children, soft or muddy areas, potholes, tire hazards, light poles, wires, low-hanging tree branches and other dangers.
  • Every backing situation is new and different. Even though a driver might visit the same location several times a day, he or she should be especially careful in these cases, looking for changes and any new obstacles at every visit.
  • Use a spotter. A driver should use another person to help when visibility is vastly limited. The spotter should not walk backwards while giving instructions. Instead, the spotter should always walk forward, turn around, then give the proper hand signal.
  • Avoid distractions. Talking on a cell phone is never a safe option while driving, and this is especially true when backing. Backing requires the full attention and skill of the driver.
  • Back up slowly. Take time to check mirrors and give any initially unseen pedestrian time to move away. Rushing to park in a space or reverse direction only increases your risk of overlooking dangers. Patience saves lives.

Speaking of patience, employees and visitors that use our taxi service are asked to be careful and wait for the Fermilab taxi to come to a complete stop both before approaching the taxi to board it and before unbuckling their seatbelts to leave. If for some reason the bus has to come to an abrupt stop and you are out of your seatbelt, you could be thrown about and injured. Also, if you slip on ice or fall when walking toward the bus and roll or slide into the path of the bus while it is still in motion, you could be seriously injured.

Let's all exercise safety precautions at all times. For more information on traffic awareness at Fermilab, visit the Traffic Safety Subcommittee website.
