CMS Detector Parts Built in Russian "Secret City"
Calorimeter Wedges

A laboratory in a Russian city that was kept secret for 35 years has provided a vital part of the CMS detector's forward hadron calorimeters. The Scientific Research Institute for Technical Physics in the city of Snezhinsk used a technique it developed, called diffusion welding, to make wedge-shaped iron matrices for the calorimeter.

"The VNIITF was contracted by the Russian Ministry of Science to build the matrices," said Fermilab's Jim Freeman, a CMS collaborator. "They pulled it off well."

Snezhinsk was founded in 1957 as Chelyabinsk-70, one of several Russian towns and cities developed for the sole purpose of weapons development and manufacturing. A city of almost 50,000 people, Snezhinsk is located in the southern Ural Mountains, 800 miles southeast of Moscow. It is still a closed city--all visitors, including residents' family members, must gain permission from the Russian government to enter or leave.

"It's a huge complex," said Nural Akchurin, a CMS collaborator from Texas Tech University who visited Snezhinsk. "To get there you fly to Ekaterinburg in the Urals and drive for two hours on country roads, and all of a sudden guards and barbed wire appear. Once you're there, you have a minder, a guy who follows you everywhere."

The city's two major facilities are the VNIITF and the Russian Federal Nuclear Centre, which employ about 80% of the adult population. By 1992, when the city's existence was finally made public, only 50% of employees were working on weapons-related activities. The VNIITF now markets its technical products and expertise to outside recipients, such as the CMS collaboration.

"What was wonderful about the city was that the people were great," said Akchurin. "They treated us wonderfully. When I got there at 3:00 a.m., there was breakfast waiting."

Accelerator Update
July 28 - July 30
- During this 48 hour period Operations established one store that combined with an existing store provided the experiments with approximately 37 hours and 38 minutes of luminosity.
- MI suffered from corrupt MECAR data table
- Recycler stashed antiprotons
- TeV quenched during dry squeeze
- Booster down due to a 480V breaker trip in the West Gallery Yard

New Physics Law Unifies Several Superconducting Compounds
UPTON, NY -- A research group led by a scientist at the U.S. Department of Energy's Brookhaven National Laboratory has discovered a simple relationship that mathematically links the properties of a class of high-temperature superconductors, materials that, below a certain temperature, conduct electricity with no resistance. This new, unexpected law applies to superconductors with very different structures and compositions, and may provide clues to understanding the mechanism of high-temperature superconductivity. It is discussed in the July 29, 2004 issue of Nature.

Safety Tip
Where the Wild Things Are
Fermilab is a welcome respite of green fields and nature in the midst of vigorous suburban development. Employees and visitors routinely take advantage, walking, biking, fishing and just enjoying the scenery. We're home to one of the largest tall grass prairies in the country, hundreds of acres of wetland, and some of the last vestiges of oak savannah in Illinois. And with the richness of the plant communities,
we are also home to a diverse collection of animal life.

Although we love to see all the wildlife, there is a down side. For every endearing bird 'n' bunny, there seem to be thousands of mosquitoes, ticks, spiders and wasps. Poison ivy, toxic plants and ecological disasters like multi-flora rose, purple loosestrife and garlic mustard abound. And even some of the cutest animals have their surly aspects!

The most common animals we have on site, including raccoons, opossums, geese, bats, foxes, coyotes -- even whitetail deer, under some circumstances, can represent hazards. Although harmful encounters between humans and wildlife are extremely rare, when they occur, it's often because of human mistakes, usually a consequence of forgetting that our wild neighbors are indeed wild; not domestic pets.

Never try to feed a wild animal, either directly or by leaving food out. That tends to break down the natural apprehension that animals have about getting too close to humans. In "surprise" or accidental confrontations, making a loud noise or acting in a threatening way normally will discourage any animal from aggression against humans. If you find that discretion is indeed the better part of valor, and need to exit, do so in a calm manner and keep your eyes on the animal -- don't run! Common sense in dealing with wildlife is still the best policy.

Have a great day and let's work safely all week!
