Back to school with
cutting-edge science

Jeremy Smith (left), a physics teacher at Hereford High School in Maryland, worked with Fermilab physicist Juan Estrada during his first summer in the DOE ACTS program. Here, Smith and Estrada test components they plan to install in a dark matter detector.

Next fall, students at Hereford High School in Baltimore County, Maryland, will get a peek at cosmic rays streaming into their classrooms from sources light-years away. They'll hear firsthand tales of working with some of the world's smartest scientists. If they're lucky, they'll get to try out a device designed to detect dark matter, one of the universe's most mysterious substances.

And that's just the beginning of what teacher Jeremy Smith hopes to bring back for students from eight weeks of research at Fermilab.

Smith is one of 11 teachers working at the laboratory through the Department of Energy's Academies Creating Teacher Scientists program. The three-year ACTS program brings middle and high school teachers to national laboratories across the country, where they spend one to two months each summer immersed in pioneering research. High school teachers such as Smith take part in a different area of Fermilab research each year, while middle school teachers focus on research in the first year and education issues in the second and third years.

"We help teachers build the skills needed for scientific investigation, and we show them ways to translate that into classroom practice," said Spencer Pasero, education program leader at Fermilab. "We also give them tools to make a broader impact at their home school," he added, noting that the middle school teachers are currently devising a professional development program for fellow teachers at their home schools.

Before this summer, Smith said he knew only the basics about dark matter and dark energy. Now, he's working with Fermilab astrophysicist Juan Estrada to develop a detector for possible dark matter particles.

"I'm trying to get Jeremy involved in all parts of the process," Estrada explained. "First, I had him looking at data we collected in the past. Then he worked on the calibration of our detector, and now he is learning about how detectors function at the level of the hardware itself."

Smith can't wait to take the lessons-and, pending a small grant, some surplus particle detectors-back to school.

"Kids get very excited about astrophysics," he said. "To have this experience, working on the real research projects, is very valuable."

Office of Science director, deputy director get behind-the-scenes Fermilab tour

On Thursday, Department of Energy Office of Science Director William Brinkman visited Fermilab with Office of Science Deputy Director for Science Programs Pat Dehmer and Associate Director of Science for High Energy Physics Dennis Kovar. After listening to a briefing given by Fermilab Director Pier Oddone about the future of the laboratory and discussing the scientific opportunities with Fermilab theorists, the group received a tour of the CDF experiment, NuMI tunnel and the MINOS detector.

Running at half-energy keeps LHC in race for discoveries

From Science, Aug. 14, 2009

The world's largest atom smasher will finally start blasting particles together this winter, but at only half of its maximum energy, officials at the European particle physics laboratory, CERN, near Geneva, Switzerland, decided last week. Officials say that energy is low enough to ensure that the 27-kilometer-long, $5.5 billion Large Hadron Collider (LHC) will not wreck itself the way it did last fall, just 9 days after circulating its first beams (Science, 26 September 2008, p. 1753). But the energy is also high enough, physicists say, to give the LHC a shot next year at surpassing its rival, the aging Tevatron collider at the Fermi National Accelerator Laboratory in Batavia, Illinois, which holds the record for the highest-energy collisions.

CERN officials have dialed down the energy to keep from overloading faulty electrical connections between the thousands of superconducting magnets that guide protons around the LHC (Science, 31 July, p. 522). Current doesn't normally flow through the questionable connections, but they need to be able to carry thousands of amps should the superconducting wire in the magnets warm up and lose its ability to carry electricity without resistance. Running at half-energy, "we have a safety margin of 2 or 2.5," says Stephen Myers, director of accelerators and technology at CERN. "It's a very conservative approach."

ES&H Tips of the Week - Safety safety

Safety monitors need their own monitoring

A personal oxygen monitor and a pocket dosimeter tossed into a drawer. Will you remember where they are? Will they work?

Portable ES&H monitoring instruments provide users with information about potentially hazardous conditions, but only if you know where to find them and how best to use them.

At Fermilab, the most common monitors measure ionizing radiation and oxygen deficiency. In order for them to be useful, these instruments must be calibrated as well as available to the people who need them. Unfortunately, smaller devices tend to get squirreled away, forgotten about and fall out of calibration. The number of instruments lost has been steadily increasing during each of the past five years, according to the ES&H Section's Instrument Calibration Team Manager, Butch Hartman.

Currently, unaccounted for are 181 personal oxygen monitors and hundreds of ionization chamber pocket dosimeters, Hartman said.

While keeping track of your monitoring equipment is important, you also need to keep it in working order. Here are two ways to properly manage your equipment so that it provides the information you need to work safely.

  • Don't use instruments that are beyond their "due calibration" dates. These devices can only be expected to provide accurate readings up to these dates.
  • Turn in unused instruments. If you are aware of your organization's procedures for turning in instruments, then you should follow them. Otherwise, you can take monitors to the ES&H Section's Radiation Physics Calibration Facility (RPCF) located at the east side of Site 38. Contact Butch Hartman at X5514 or at bhartman@fnal.gov.

Tune IT Up

Tune IT Up Q&A

Q: I cannot complete the IT assessment because the system does not recognize the property tag # SI-xxxxx. What should I do?

A: Property tags that begin with the letters SI are no longer in use. If your computer has another tag, such as a blue CD-system tag starting with the letter 'S' or a yellow property tag with just a number on it, use that instead.

Q: I have a computer that is not currently in use or even powered. Do I need to enter information about it in the Tune IT Up assessment?

A: If you do not expect to use the computer again, please take it to the Prep counter at the Feynman Computing Center, just beyond the main doors on the East side. If you would like to keep the information on your hard drive, you can store it on an external device or call your system administrator for help.

If you keep the computer, please fill out the assessment for it. We recommend keeping computers on the network and powering them up at least once every few weeks so that the operating system can be upgraded, patches installed, and antivirus signatures kept reasonably current.
