Fermilab Inaugurates StarLight Connection Officials at Fermilab announced yesterday a potential five-hundredfold increase in the laboratory's computer network connections to U.S. and international science communities. A new high-performance optical
StarLight is a high-performance network exchange for many worldwide
research and educational wide-area networks. A 92-kilometer optical
fiber connects Fermilab with the StarLight facility, enhancing
Fermilab's high-speed connectivity with universities and institutions
in North and South America, Europe and Asia. Such advanced networks
are necessary in the global field of particle physics-scientists from
31 countries currently collaborate on Fermilab experiments.

From PhysicsWeb, July 1, 2004 New shift seen in cyclotrons A subtle change in the motion of charged particles in magnetic fields has been discovered by physicists in the US. David Pritchard and colleagues at the Massachusetts Institute of Technology have shown that the resulting shift in the cyclotron frequency of the particle can be used to measure its quantum state (Nature 430 58). The effect could be used to measure the dipole moments of molecular ions, test fundamental symmetries, and weigh individual chemical bonds.
Cyclotrons are routinely employed to compare the masses of molecules and study chemical reaction rates. The cyclotron frequency is given by the simple formula qB/m, where q and m are the charge and mass of the particle and B is the magnetic field. However, Pritchard and co-workers have discovered that this formula needs to be tweaked for particles that can be polarized. This happens because an electric dipole moment is induced in the particle and the two ends of the dipole move at slightly different speeds. The end result is that the cyclotron frequency is shifted by a small amount.

Photographer Peter Ginter Builds Unique Image Archive | ||

On Wednesday, world famous photographer Peter Ginter returned to Germany after
spending 10 days at Fermilab photographing employees and experimental equipment.
"I was able to get a lot of work done because everyone was so gracious," said
Ginter, who completed 25 photo shoots. "Everything was perfectly organized,
which put more pressure on me because I had no excuses."
In addition to photographing installations such as the NuMI horn, BTeV
test stand, and the Main Injector, Ginter took a time-lapse photo of the
Booster ring from the tenth floor of Wilson Hall, which involved three
circling fire trucks and contributions from a crew of 16 people.
"He's earned his reputation in photography by working seven days a week, day and night, but he still gets excited when faced with a challenging photo," said Fred Ullrich of VMS, who helped organize the time-lapse photograph. "His ability to preconceive a great picture is a really unique gift." To get a "great picture," Ginter photographs a piece of equipment several times under different lighting conditions, then uses a computer program to stitch all of the photos together. The end result is a colorful, multilayered picture that makes even the most mundane hardware appear exotic.
"We want to thank all of the 100 people involved in making this a success,"
said Kurt Riesselmann of Public Affairs, Ginter's guide and assistant when
he was on site. "He worked like crazy, but our employees were able to keep
up with and accommodate him."
