Syphers says Tevatron has power of two jelly donuts
The Tevatron accelerates two particle beams to near the speed of light. Their combined kinetic energy equals about 800 dietary calories--or two jelly doughnuts.
To super-cool 1,000 magnets and zip two beams of particles near the speed of light, Fermilab's Tevatron uses 12.2 megawatts of power--enough to power 61,000 personal computers. But when the beams reach their maximum speeds, the particles only possess the energy of two jelly doughnuts, said Mike Syphers of the Accelerator Division on Tuesday.

As part of an ongoing lecture series for the Summer Internships in Science and Technology (SIST) program, Syphers helped interns get up to speed on particle accelerators. From basic physics to the development of the first cyclotron in 1931, he left few stones unturned--including the doughnut-level energy of each proton and antiproton beam in the Tevatron.

"It really doesn't sound like a lot, but try eating two jelly doughnuts in 21 microseconds," Syphers said. "When you do the math, the energy in each beam is about 400 dietary calories." In other words, the energy stored in the beams could boil two and one half gallons of room-temperature water instantly.

Some other fun facts presented during the lecture:

  • The first circular particle accelerator, developed by E. O. Lawrence, can fit in the palm of a hand.
  • A typical TV set can accelerate particles to 20 percent of the speed of light.
  • It takes only 0.033 seconds for Fermilab to get a beam of protons up to 99 percent of the speed of light
  • Tevatron's magnets are cooled to a chilly -450 degrees Fahrenheit.

    Upcoming SIST lectures and a PDF version of Syphers' lecture can be found here.

  • Excavation experts bask in MINOS's subterranean glory
    This group of excavation experts took a tour of MINOS Hall last Thursday. (Click on image for larger version.)
    MINOS Near Hall wasn't built in a day. In fact, it took 180 people digging for twenty months to just make the cavern. Last Thursday, a group of civil engineers who specialize in underground excavations came to see the 350-foot-deep Hall and learn about how it was made.

    After a series of short lectures about the ILC, Fermilab physics, neutrinos and NSF's proposed DUSEL lab, the engineers were given a tour of the detector hall at MINOS. Chris Laughton, the Fermilab civil construction manager on the MINOS project, outlined the methods, challenges and solutions involved in the excavation. "When you think of physics you think of white lab coats and everything has to be perfectly clean and air tight. It's nice to see an example of good, cost-efficient engineering," said Michael Crow after his tour of MINOS.

    The lecture on the ILC outlined the immense difficulties involved in mining two parallel tunnels, roughly six meters wide and thirty-five-kilometers long. (So long that engineers need to account for the curvature of the earth in their plans.) "They're really going to be pushing the threshold of underground excavations," said Crow.

    After the tour, the group ate lunch and got back on the bus to return to Chicago. "It's trips like this that remind you why you became a civil engineer. It's great to see your work being used for something, and when people start talking about quarks and muons...it's just great to see," said Crow.

    Berkeley Lab's Saul Perlmutter Wins Shaw Prize in Astronomy

    BERKELEY, CA - Saul Perlmutter, a member of the Physics Division at the U.S. Department of Energy's Lawrence Berkeley National Laboratory, professor of physics at the University of California at Berkeley, leader of the international Supernova Cosmology Project, and principal investigator of the SuperNova/Acceleration Probe (SNAP) project, has won the Shaw Prize in Astronomy for the discovery that the expansion of the universe is accelerating.

    Perlmutter shares the $1 million prize with Adam Riess of the Space Telescope Science Institute and Brian Schmidt of Australia's Mount Stromlo Observatory. The presentation ceremony is scheduled for Tuesday, September 12, in Hong Kong.

    The Canadian ILC Group and the Time Projection Chamber
    A 30-cm TPC prototype that the ILC Canada group built and used in magnetic field tests at TRIUMF and DESY.
    Although it sounds like a device used on Star Trek, a Time Projection Chamber (TPC) is a gas-filled cylindrical chamber that acts like a three-dimensional electronic camera, making a photo-copy of a particle track as it flies through the detector. For about a decade now, a group of scientists in Canada has been developing and testing Micro-Pattern Gas Detectors (MPGD), contributing to the worldwide R&D for a high resolution TPC tracker for the future International Linear Collider.

    Yesterday's DASTOW a huge success: sampling of images
    DASTOW participants gathered in front of Wilson Hall for a photo at 8:45 am. Some sons and daughters returned to their parents' computers to design a web page after the photo was taken.
    Mr. Freeze (PPD's Jerry Zimmerman) illustrated physics principles with liquid nitrogen at the 9:00 am cryogenic show.
    Parents and children visited the Fermilab Fire Station at 10:00 am.
    DASTOW participants visited the buffalo pasture after lunch.
