A menagerie of instruments
A recent division head column by Bill Griffing mentioned radiation monitors called "chipmunks." Here are other Fermilab instruments with whimsical names.
The "scarecrow," here on a break from its usual job location
Fermilab's ES&H Section Instrumentation Team is the caretaker of a unique menagerie: albatrosses, chipmunks, hippos, pterodactyls, scarecrows, and an aardvark to name a few. These radiation detection instruments are designed and built in-house. "Everyone here knows what they are, but no one else would in the world," said Butch Hartman, team co-leader. The origin of the names is often part of lab lore.

In one legend, an employee working in frustration on a radiation instrument in the late 60s dubbed his instrument the "albatross," alluding to the poem "The Rime of the Ancient Mariner" and the sailor who wears an albatross around his neck as a burden. The "scarecrow," an instrument mounted on a tripod, would--if it detected unacceptable levels of radiation--warn people to stay out of an area, like crows warned to stay out of the cornfield. A piece of hardware called "aardvark" collects little, termite-like bits of radiation data and has a long, protruding trunk-line. "Hippos" are rotund and gray.

The stories of some names have been lost. The "pterodactyls"? "I really don't know how they were named," said John Larson, team co-leader. "But it's a conversation starter; it's not boring. You get tired of hearing acronyms all the time."

SLAC Press Release,
September 28, 2006:

New Form of CP Violation Discovered
Finding something expected has brought researchers at the Department of Energy's Stanford Linear Accelerator Center (SLAC) one step closer to discovering the unexpected.

SLAC's BaBar collaboration has discovered that CP violation-an asymmetry between the behavior of matter and antimatter-exists even in a very rare class of particle decays. This result offers the most sensitive avenue yet for exploring matter-antimatter asymmetries, with implications for the future understanding of physics beyond the Standard Model.

"BaBar has proven to be a fantastic instrument for exploring the origins of matter-antimatter asymmetries, allowing us to probe with exquisite precision very rare processes related to how the early universe came to be matter dominated," said David MacFarlane, BaBar Spokesperson and Professor at the Stanford Linear Accelerator Center.

Safety Tip
Electrical glove testing due
Are you a Fermilab employee who uses electrical insulating gloves as part of your job? If so, you have likely been provided both a black and blue pair. The black pair of gloves that you have been using must now be re-tested. October 2 is the date established by the Fermilab Glove Testing Program to submit your black pair for testing. It's also time to start using your blue pair from now until the end of March 2007.

Once put into service, insulating gloves must be re-tested every six months by an offsite testing facility. If you have not already turned in your insulating gloves for testing, contact your Division/Section ES&H organization for assistance.

Insulating gloves are a critical component in protecting workers from electrical shock. They are rated in "Classes" according to the level of voltage protection and, like most apparel, are available in different sizes. Leather "protector" gloves are worn over the insulating gloves to minimize abrasion and puncture damage. Class 0 gloves, the most common type provided, offer shock protection up to 1000 volts AC or 1500 V DC. NFPA 70E and safe work practices often demand that that you wear insulating gloves when close to bare energized conductors or parts.

Wear your gloves when needed and check them regularly by examining the gloves for holes, cracking or surface degradation. Defective gloves must not be used and must be immediately replaced. If you think you need electrical insulating gloves for your job and do not have them, contact your local ES&H organization immediately. If you have any questions about glove use, contact your Division/Section Electrical Coordinator or any member of the Electrical Safety Subcommittee.
