CDF implements clever leak fix during shutdown

Mike Lindgren, PPD CDF department head, shows the plastic seal built around the western silicon detector to give workers access to water cooling tubes while keeping the detector cool and dry.

To fix a multistory, multimillion-dollar detector, CDF employees had to think small. Really small.

Pencil-sized aluminum tubing bringing cooling water to the electronics covering the silicon detectors deep in the heart of the CDF machinery sprang a leak. Without cooling water, the outer layers of electronics shut down, limiting data taking on the east side of the detector for the final two months before the summer shutdown.

The crew had to find a way to plug the leak at a faulty weld without taking the entire silicon structure apart, which wasn't possible.

"There is just no way you can get to the outside of it," said Mike Lindgren, PPD CDF department head. "You can only work through these tubes."

With the help of Ken Schultz, operations specialist with PPD, Peter Wilson, the CDF operations co-head, and his staff found a solution.

Using medical tools that doctors normally snake through human arteries, Schultz fashioned a camera that threads through the coolant tubing to find the leaks. Schultz also designed a tool to cover the welds with epoxy from inside the tubing. All 16 of the aluminum welds were sealed as a preventative measure.

That fix was by far the most complicated of many CDF repairs made during the shutdown, Lindgren said.

Scientists and technicians at CDF had to design and build a special environment to allow the coolant system repairs while keeping the silicon detectors healthy.

Fermilab scientists join European Researchers Night

From left: Matthias Neubert, Marcela Carena, Michael Schmidt, Chris Quigg and Sabine Lammers.

Museums, universities and laboratories throughout Europe opened their doors on Friday night and invited the public to the third European Researchers Night. And from across the ocean, Fermilab joined in - virtually. Organized by Matthias Neubert, a physicist who is visiting Fermilab for a few months, a group of scientists here at the laboratory participated in the European event by video conference. Fermilab scientists answered questions posed by a group of participants who had gathered at Neubert's home institution, the University of Mainz in Germany. More than 150 cities in 29 European countries offered a broad range of events connected to the researchers night.

Scientists ask Congress to fund $50 billion science thing

From The Onion, Sept. 28, 2007

Top physicists from several major American universities appeared before a Congressional committee Monday to request $50 billion for a science thing that would further U.S. advancement science-wise and broaden human knowing.

The scientists spoke for approximately three hours about the complicated science machine, which is expensive, and large, telling members of the House Committee on Science and Technology that the tubular, gamma-ray-using mechanism is vital in some big way. Yet the high price tag of the thing, which would be built on a 40-square-mile plot of land where the science would ultimately occur, remained a pressing question.

After 10 years, we still can't find most of the universe

From The Houston Chronicle, Sept. 29, 2007

'Dark energy' is real, scientists say, though they don't know what it is.

Ten years ago, an unexpected astronomical discovery stunned the scientific world: Two rival teams of astrophysicists claimed that most of the universe is made of an invisible substance they called "dark energy." Only a tiny fraction, they said, consists of the ordinary atoms that make up stars, chairs and people.

Dark energy has shaken the fields of physics and astronomy, much as Copernicus did 500 years ago when he declared that the Earth revolved around the sun, not the other way around.

Safety Tip of the Week

Flu shot season

Safety Tip columnist Tim Miller receives a flu shot from the Medical Department's Mae Strobel.

Are you debating whether to get a flu shot this year? Not everyone will contract influenza during the upcoming cold and flu season, but why take a chance? Fermilab's onsite Occupational Medical Director Dr. Brian Svazas said the shot is 70 to 90 percent effective in preventing infection, and even if you do catch the flu, the symptoms will be lessened.

Maybe you got sick the last time you had the shot and worry that will happen again. According to Svazas, sickness after the flu shot usually means you suffered from another infection, not influenza.

Svazas adds that it's especially important to get a flu shot if you have a chronic lung problem such as emphysema, chronic bronchitis or asthma. People with these conditions have more difficulty clearing their lungs, and they are prone to pneumonia, the most common kind of secondary infection.

The flu shot also can serve as a diagnostic tool for more serious illnesses. In the unlikely event that avian flu becomes transmissible from person-to-person, inoculation against the regular flu can provide diagnostic information. It can help prevent a "false alarm," as the most common cause of a flu-like illness has been excluded. Additionally, not getting the seasonal flu disease during such a pandemic means that you will not need to seek care during a time when the system is overtaxed and you have to sit in a waiting room where something worse may be waiting for you.

On Wednesday, Oct. 3, Fermilab will hold the first of two vaccination clinics. This first clinic is for employees who have an increased risk of suffering severe illness in the event of infection. The general employee population can attend the November clinic. Additional information about the Fermilab program and an online schedule are available on the ES&H Section's home page . The Visiting Nurse Association and American Lung Association also will provide flu shots and have posted their shot schedules for the 2007-2008 season.
