Irina Kubantseva retires

Irina Kubantseva examines chemicals in Lab 6 in 2009.

As part of her job, Irina Kubantseva scrutinized silver-dollar-sized plastic wafers and reflective chemicals in an area resembling a forensic laboratory.

She looked for clues that the material wouldn't work as a scintillating detector, which emits light to signal when a particle crosses its path. It's a crucial part of R&D, catching problems before industry starts manufacturing PVC for what will be the world's largest plastic detector, NOvA. Kubansteva, who worked at Fermilab for almost 11 years, checked her last PVC piece April 16.

"She was a very resourceful person who provided continuous, reliable support to our projects," said Anna Pla-Dalmau, leader of PPD's scintillation detector development group. "She had great attention to detail."

Because of her background in biochemistry, Kubantseva's work in the chemistry lab, especially on NOvA, was her favorite.

"She was eager to learn," Pla-Dalmau said. "She was always interested in learning to use a new instrument."

Along with the other three technicians in the chemistry lab, Kubantseva was also part of the preparation and quality control of extruded plastic scintillator for the MINERvA experiment at Fermilab, as well as for experiments in Japan and Italy.

She's disappointed she won't get to see NOvA completed but plans to visit the detector's future home at the Minnesota-Canada border after moving to Minnesota to dote on a granddaughter.

Her co-workers, a tight-knit group, say they'll miss her conversations about music and her hometown, Moscow.

"We're a small group. We went out for lunches. We are friends," said Chuck Serritella, an operations specialist in the SDD group.

Serritella trained Kubantseva when she followed her husband, Mikhail, a retired DZero collaborator, to Fermilab. She started at SiDet, assembling detector parts under a microscope. It took a steady hand to align to within 2.5 microns small silicon wafers for DZero's silicon tracker and later to glue the wafers to the detector, prepare them for binding and help with quality inspections.

"She did some very precise work," Serritella said.

Skilling talks twisters at annual weather seminar

Meteorologist and local celebrity Tom Skilling, right, meets with members of the audience after the annual tornado and severe weather seminar at Fermilab on Saturday, April 10.

The crowd at the seminar numbered in the thousands. Fans come from around the country every year to learn about recent severe weather. This was the 29th time Fermilab hosted the event.

One step closer to understanding dark energy

From Discovery News, April 23, 2010

According to the most precise cosmological models to date, dark energy is a mysterious repulsive "force" that makes up the majority of the total energy contained within the universe. And yet, we have no idea what it actually IS. The Lawrence Berkeley National Laboratory's Supernova Cosmology Project is helping us get a bit closer to the answer.

Type Ia supernovae (that's "type one aye") occur when a white dwarf star gobbles up too much mass from its less massive companion star and detonates, creating a massive explosion that can outshine a whole galaxy. An explosion occurs when the white dwarf hits a specific mass, so we know how bright these explosions should be.

ES&H Tips of the Week - Environment

Keep ticks at bay with a little preparation

The American dog tick lives on the Fermilab site.

Fermilab employees report that ticks have made their seasonal appearance at the laboratory, but with a little planning, you can still enjoy your time outside and stay healthy.

The American dog tick is the largest of the Eastern wood ticks and the most common type found in Illinois. They are most active during the months of April and May. American dog ticks don't carry Lyme disease, but they can transmit Rocky Mountain spotted fever.

Deer (or blacklegged) ticks, though rare in this area, can transmit Lyme disease. Due to the seriousness of these diseases, you should minimize the chance of receiving tick bites, even though the risk of infection due to tick bites is slight.

Here are some tips that will help you keep ticks off your skin:

  • Avoid - Avoid deep woods and tall grasses. Stay on paths and mowed surfaces.
  • Cover - Cover up your skin as much as possible. Tuck pants into socks, and long-sleeved shirts into pants. Wear light colors so you can spot ticks easily.
  • Repel - Repellents help, especially for exposed skin and areas where ticks can enter clothing. Use DEET on skin and Permethrin on clothes.
  • Check - Inspect your body periodically when spending time in tick habitats. Ticks often reside near ankles and waists, but they can crawl anywhere.
  • Remove - Use sticky tape to remove unattached ticks. To remove embedded ticks, our Medical Office recommends the use of tweezers. Remove ticks as soon as possible, as the infection risk increases with duration of attachment. Using the tweezers, firmly grasp the tick as close to your skin as possible and gently but firmly pull it straight out. Make sure you get all the mouth parts. Wash with soap and water. If you want help, the Medical Office can assist you.
