| Roof repairs ready for leaky Meson Lab |
||
| ||
|
The Meson Laboratory's scalloped roof is part of Fermilab's architectural heritage from founder Robert Wilson and in-house artist Angela Gonzales. The design, while an aesthetic success, is flawed functionally. The weakness lies in the corrugated steel arches, the ridges of which run perpendicular to the flow of the water. "They do not encourage water to move from the roof," said Elaine McCluskey, FESS Project Engineer. The roof has many steel-to-steel connection points, which provide inlets for water. Unlike the roof of a house, in which shingles coat a frame support, the Meson arches are both the roof's structural support and its outer barrier. Without a watertight coating, the roof has been leaking almost since it was built.
Repairs will begin the second week in October and last up to two months, if the weather is cooperative. Workers will continue to use the building during repairs. The contractor will set up scaffolding next week to access the roof; employees should not walk under the scaffolding unless they are using a posted entrance or exit. As the final step of the repairs, the contractor will spray on a rubber sealant. Meson Lab workers will need to park only in posted areas to protect their cars from sealant spray. The renovation will include power-washing, filling in cavities with a mastic-type material and two coats of a spray-on rubber coating. The material, used in many industrial roofing applications, will dry as a sheet. The material's manufacture said Fermilab's Meson roof is one of its most unique uses.
Once finished, the contractor has guaranteed the roof to be water-tight for 10 years. The roof will be restored in the bright blue and terracotta colors used throughout Fermilab, in line with the original design intent. "The architectural legacy of Dr. Wilson is something we try to preserve as we remodel buildings and look to future facilities," said McCluskey.

WorldScience.net, September 25: Physicists seek to put one thing in two places Physicists say they have made an object move just by watching it. This is inspiring them to a still bolder project: putting a small, ordinary thing into two places at once. It may be a fantasy, admits Keith Schwab of Cornell University in Ithaca, N.Y., one of the researchers. Then again, the first effect seemed that way not long ago, and the second is related.
The research comes from the edge of quantum mechanics, the submicroscopic realm of fundamental particles. There, things behave with total disregard for our common sense.

| Virtually there - the control room of the future? | ||
"I was in a hotel room in Berkeley, California, and was able do all the things you can normally do in the HERA control room and nowhere else," explains Ferdinand Willeke, one of the developers of the new tool. His partners in the project, the 20-strong collaboration (an Italian-German EUROTeV workpackage), were in a meeting at DESY in Hamburg, Germany. After 1.5 years of programming work on the Global Accelerator Network Multi-Purpose Virtual Laboratory (GANMVL), the international team set up their prototype for the first time. "It's a great success. Naturally we found a couple of things that need fixing, but that will help us improve the system," says Matthias Kasemann, leading scientist at DESY. The next step is to offer it as a tool to the whole community for testing and use - the next guinea pig for the virtual lab is the Calice collaboration. They run a test of their calorimeter at CERN in October and will try to control it remotely.
