From symmetry

Probing the heart of the atom

Illustration by Sandbox Studios

The familiar elements of the Periodic Table come in a number of forms, or isotopes-some found only fleetingly in the most violent events, such as exploding stars. By creating those rare isotopes in the lab, physicists are learning how the atomic nucleus works and deciphering the natural history of the elements.

Andreas Stolz has a problem. Because of advances in superconducting magnet technology, the Michigan State University assistant professor desperately needs a new metaphor to describe the process he and his international collaborators use to create and isolate exotic nuclei.

Stolz is a physicist at MSU's National Superconducting Cyclotron Laboratory, or NSCL, one of a handful of facilities worldwide that produce rare isotopes using fast-beam fragmentation. Here's how it works: Scientists accelerate a beam of stable, ionized nuclei to nearly half the speed of light and slam it into a thin metal target. The resulting spray of reaction products continues down the beamline, where a network of magnets separates a few sought-after rare isotopes from the rest of the nuclear chaff. This cutting-edge technology helps scientists probe deeper than ever before into the origins and properties of the atom's core.

Special Announcement

DASTOW '09 set for June 10

After a year's absence, take your Daughters and Sons to Work Day returns to Fermilab Wednesday, June 10. The day will feature several events from 8:45 a.m. to 2 p.m. including: the Cryo Show by Mr. Freeze, bus tours to the buffalo pasture to see the babies, prairie tours, a Fire Department open house and experiment demonstrations. Hot dogs will be provided for lunch. Watch Fermilab Today for more details in the coming weeks.

Fermilab ships completed 3.9GHz cryomodule to DESY

Fermilab's first 3.9GHz superconducting RF cryomodule sits completed in the Industrial Complex Building. It was shipped to DESY on Friday. The cryomodule, which arrived safely on Tuesday, April 28, will become part of the FLASH free-electron laser.

Plan for tour groups frequenting Fermilab

Spring means changes at Fermilab. It brings out the song birds, baby bison and groups of students touring Wilson Hall.

The tours, which will occur frequently during the next two months, sometimes more than one a day, give students and adults in surrounding towns and as far away as Chicago a chance to learn about the science done at the laboratory experiments and in the prairie.

The tours are a great way to generate interest in the sciences and support for Fermilab's future proposed projects, as well as show that the laboratory works to be a good neighbor.

Docents try to schedule tours around the normal work of the laboratory, but school and bus schedules often mean tours coincide with the lunch hour and times when people frequently use the elevators.

While it's easy to get frustrated by long lines in the cafeteria or at the elevators, please try to remember the tours are part of the laboratory's outreach mission.

And just like spring, the tours will pass.

Nasa scientists snap most distant object in the universe

From Telegraph, April 28, 2009

Astronomers at Nasa have snapped a picture of the most distant object ever seen in the universe - a titanic burst of energy from a dying star 13 billion light years away.

The "gamma ray burst" is so far away that its light has taken almost the entire age of the universe to reach us.

When the light began its journey, travelling at 186,000 miles per second, only 640 million years had passed since the Big Bang that marked the dawn of creation.

The event, designated GRB 090423, was first detected by the American space agency Nasa's Swift satellite, which is designed to spot gamma ray bursts.

After Swift recorded an initial blast of gamma and X-rays, ground-based telescopes swivelled to aim at the same point in the sky and observed a fading afterglow of infra-red light.

From the Accelerator Division

Preparing like a wirewalker

Roger Dixon, head of the Accelerator Division, wrote this week's column.

Roger Dixon

Another accelerator shutdown is nearly upon us. It will begin in the middle of June, and we will have a lot of very challenging work to do. We will need to plan our work carefully so that we can get it done safely and on schedule.

Working in the accelerator enclosures requires focus and concentration. I was reminded of this several weeks ago when I watched a documentary titled "Man on Wire." It is the story of the French wirewalker, Philippe Petit, who in 1974 successfully walked on a high wire that he secretly, and illegally, strung between the twin towers in New York City.

Such a dangerous stunt requires incredible focus and preparation. When walking the wire, one cannot let thoughts of plunging to the street below become distracting.

I asked myself how Fermilab would approach such a dangerous task. The first things that popped into my mind were appropriate training and the use of safety equipment. I envisioned an expensive mattress as fall protection and a wire only inches above the mattress. My setup would not attract much attention, but I would not end up splayed out like a bug on a windshield either.

But just practicing the steps isn't the full answer. Like all human beings, I get distracted every few minutes. Any safety plan would have to take this into account.

I would like everyone to think about this for the shutdown. When you find out where you will be working, think about what could happen if you got distracted and how to prevent injury when a distraction occurs. Take the time to make your work area safer. Make sure that you have the proper tools and wear the right personal protection for the job. By making your work area safer, you will help yourself and your co-workers.

Remember, once you fall off the wire, it is too late to grow wings.

Earth Day/Arbor Day celebration postponed

Plant a tree on April 30.

The Earth Day/Arbor Day tree planting and celebration that was scheduled for Thursday, April 30, has been postponed due to wet ground conditions. Roads and Grounds staff plan to hold this event on Tuesday, May 5, at 11:30 a.m., weather permitting. Please check Fermilab Today for updates.

Safety Update

ES&H weekly report, April 28

This week's safety report, compiled by the Fermilab ES&H section, lists one case reported to the Medical Department last week. An employee strained a shoulder while lifting 50-pound fan elements to change HEPA filters. This case resulted in time away from work. Find the full report here.
