Fermilab NLC Team Reaches Milestone
LC Group

Fermilab scientists and technicians working on radiofrequency research and development for the Next Linear Collider reached a milestone two weeks ago, when the final RF structure to be used in a test of the X-band Linear Collider technology was shipped to SLAC. In the upcoming "8-pack" test, the RF structures will be used with high-power klystrons to demonstrate the high-accelerating gradient performance of the technology.

"A successful 8-pack test will serve as a 'proof of principle' of the fundamental elements of the NLC," said Project Engineer Harry Carter. "Fermilab built six RF structures for the test, four of which are installed in the 8-pack along with four fabricated by SLAC and KEK."

The Fermilab team of technicians, engineers, physicists and a mathematician has been working on the project for two and a half years. RF design, mechanical design and assembly and low-power testing are carried out at the lab's RF structure factory in Industrial Building 4. Several versions of the structures have been produced at the lab, with one more version planned. The current version is 60 cm long and contains 52 copper cells of slightly different internal dimensions.

DASTOW, Earth Day Tomorrow!
DASTOW 2003 participants (Click on image for larger version.)
Fermilab's annual Daughters and Sons to Work (DASTOW) and Earth Day activities will celebrate the lab's valued connections with employees and their families tomorrow, April 22.

Highlights of the day include a special rescue re-enactment by the Fermilab Fire Department, the Cryogenics Show with Jerry Zimmerman in Ramsey Auditorium, Butterflies at Fermilab with Tom Peterson and the buffalo pasture visit with herdsman Don Hanson. These events are open to all comers, and special DASTOW buses will provide transportation. If you haven't signed up for the cafeteria lunch yet, please place your orders today so we have an approximate count for ordering hot dogs. And don't forget to smile for the official DASTOW Group Portrait on the front steps of Wilson Hall at 8:50 a.m. An information desk will be set up in the Atrium, where you can also register for education programs.

The Roads and Grounds Department will sponsor its annual Earth Day tree planting and a picnic lunch beginning at 11:30 a.m., so plan to bring your work clothes and your appetite.

Remember, the No.1 priority for DASTOW and Earth Day is for everyone to have a safe day. We look forward to seeing you and your families tomorrow.

Memorial Service for Harry Melanson
Harry Melanson, a Fermilab physicist on the DZero experiment, died unexpectedly on Saturday, April 17. There will be a memorial visitation on Saturday, April 24 from 9:30 a.m. to 11:30 a.m. at the Moss Family Funeral Home, 209 South Batavia Avenue in Batavia. A service will be held from 11:30 a.m. to 12:30 p.m. Donations should be given to the Batavia Community Chest, (630) 406-9219.

From Scientific American, April 19, 2004:
Shattered Glass
Seeking the densest matter: the color glass condensate
By David Appell
Physicists investigating heavy-particle collisions believe they are on the track of a universal form of matter, one common to very high energy particles ranging from protons to heavy nuclei such as uranium. Some think that this matter, called a color glass condensate, may explain new nuclear properties and the process of particle formation during collisions. Experimentalists have recently reported intriguing data that suggest a color glass condensate has actually formed in past work.
