Bubble chamber gets more precise in dark matter search

The 1970s were a thriving time in the world of physics, heralding such milestones as the development of the Standard Model and the discovery of the bottom quark. Now scientists at Fermilab are bringing some experimental pieces of that era back – bubble chambers and fixed-target physics.

Peter Cooper, a Fermilab physicist, is heading a new experiment calibrating the classic bubble chamber technology, which is used today to search for dark matter.

The Chicagoland Observatory for Underground Particle Physics (COUPP) collaboration looks for bubbles in chambers filled with a compound containing carbon, fluorine and iodine. The fluid is superheated beyond the boiling point but has no rough surface to form bubbles. When a specific type of particle interacts in the chamber, it can deposit enough energy to boil the fluid and make a bubble. Electrons do not produce bubbles, while a dark matter particle interacting with a nucleus can – making this the key for dark matter detection.

John Urban retired - Oct. 7

John Urban

John Urban and the Tevatron started at Fermilab right around the same time. Urban was in the air force for seven years before he joined Argonne National Laboratory. He spent 17 years there before he joined Fermilab in 1985, as a high-level RF tech specialist. He retired from the laboratory on Oct. 7.

“I spent 26 years here,” Urban said, smiling. “Evidently, I liked it.”

Urban recently completed building two bias supplies for the NOvA experiment. The supplies will help reduce the Main Injector cycle time to 1.33 seconds from 2.2 seconds. According to Joe Dey, Urban’s supervisor, Urban’s impending retirement put a crunch on construction.

“I knew Urban was going to retire on me one of these days,” Dey said.

Dey said that the cavities were the first part of the project approved, so that Urban could get to work on the two supplies. And the work was excellent.

“John has always taken great pride in his work,” Dey said.

While Urban will miss his work, he’s excited to sleep in.

“I didn’t mind getting up in the morning for work,” Urban said. “But I’m happy to turn off the alarm clock.”

Higgs boson reality or chimera? Next year will show

From Reuters, Oct. 6, 2011

The long-sought Higgs boson, believed to have given shape to the universe after the Big Bang, will be found in the next 12 months or shown to be a chimera, heads of the three top physics research centers said on Thursday.

And the three scientists -- from Europe's CERN, the U.S. Fermilab and Japan's KEK -- also pronounced themselves skeptics on whether neutrino particles had broken accepted natural laws and travelled faster than the speed of light.

"I think by this time next year I will be able to bring you either the Higgs boson or the message that it doesn't exist," declared Rolf Heuer, director general of CERN whose Large Hadron Collider (LHC) is at the focus of the search.

He was echoed by KEK's Atsuto Suzuki and Pier Oddone of Fermilab, which last weekend shut off after 26 years its Tevatron accelerator, which has also been seeking the Higgs in the debris of billions of particle collisions.

ES&H Tip of the Week:

Fire safety means making and practicing an evacuation plan

Fermilab wants its employees and users to be safe at home as well as at work. That's why we want you to be prepared to handle a house fire.

According to a National Fire Protection Agency survey, only one of every three American households have actually developed and practiced a home fire escape plan, and even then many underestimate the amount of time they have to escape. When polled, one-third of Americans said they would have at least six minutes before a fire in their home would become life-threatening. The time available is often far less. Only eight percent of people said that their first thought on hearing a smoke alarm would be to get out.

Here are some safety tips to improve your preparedness:

  • Make a home escape plan.
  • Draw a map of your home showing all doors and windows.
  • Discuss the plan with everyone in your home.
  • Know at least two ways out of every room, if possible.
  • Make sure all doors and windows leading outside open easily.
  • Have an outside meeting place (such as a tree, light pole or mailbox) a safe distance from the home where everyone should meet.
  • Practice your fire drill twice a year, both at night and during the day, with everyone in your home.
  • Practice using different ways out.
  • Teach children how to escape on their own in case you can’t help them.
  • Close doors behind you as you leave.
  • If the alarm sounds, get out and stay out. Never go back inside for people or pets.
  • If you have to escape through smoke, get low and go under the smoke to get out.
  • Call the fire department from outside your home.

National Fire Prevention Week is Oct. 9 through Oct. 15. Make your plan and practice it.
