Overwhelming Turnout at Lab Party
The balloon-decorated atrium was abuzz with talk and music as the largest crowd in recent history came to the URA-sponsored lab-wide party on Friday afternoon. Party organizers estimated the number of participants at more than 1,200 people, about 50 percent higher than in the past. In fact, so many partygoers turned up that food and drink ran short before the evening was out.

"I think that we were all pleased with the turnout and response, even if it overwhelmed us," said Jeff Appel, who chaired the organizing committee. "Everybody seemed to have a good time."

Partygoers enjoyed the posters that highlighted the lab's past 35 years as well as achievements of the past 12 months. (The posters will remain on display in the atrium until December 8.) Evergreens such as "Macarena" and "YMCA" drew people to the dance floor, and many employees stayed past 6 p.m. for the last dance as well as the final drawing of door prizes.

Fermilab Today and the organizing committee would like to hear from you about the party. Please send your comments and suggestions to today@fnal.gov. Photos of the party are posted on-line.

So Far, So Good

After the 10-week shutdown, the Tevatron officially had its first collisions over the weekend. "The start-up is going very well," said Doug Moehs, Beams Division Proton Source. "This first store was primarily used to work on the mechanics of transferring antiprotons from the Antiproton Source to the Tevatron. It was pretty successful." Operations will continue to do shots throughout the week to work on the mechanics of the machine. The primary goal over the upcoming weeks is to increase the stacking rate and proton luminosity. The start-up so far has indicated many areas of progress in the accelerator complex. "The recycler vacuum work is being considered a success, and the emittance blow-up had a reduction by a factor of three. These are early signs that things are going well," said Moehs.

Good Morning!

Mike Witherell

It's an exciting week at Fermilab as the accelerators come back to life after the shutdown that began last September. At this early stage, I am pleased to report, the progress of the start-up is very encouraging. The Beams Division achieved first collisions in the Tevatron by last Sunday, as planned, with a luminosity of 8.9E30. The vacuum in the Recycler shows the expected improvement. We can proceed to the planned next stage, commissioning the Recycler with antiprotons . Realignment and straightening of Tevatron magnets have reduced the need for correction elements to keep the beam on track. Perhaps best of all, early results indicate that the improvements that we undertook during the shutdown give the promise of more stable and longer-lasting Tevatron beams during normal operation. With time and effort in the weeks to come, these improvements will lead to more integrated luminosity delivered to the experiments.

This Thanksgiving week, we have much to be thankful for at Fermilab. People from all parts of Fermilab worked long and hard to make the most of this all-important shutdown. They worked skillfully and safely to bring us to this point, back in business for Run II and the physics that awaits us in the year ahead. They have the thanks of all of us.

To everyone in the Fermilab community, I wish you and your families a very Happy Thanksgiving 2003.

Most distant x-ray jet yet discovered provides clues to big bang
The most distant jet ever observed was discovered in an image of a quasar made by NASA's Chandra X-ray Observatory.

Extending more than 100,000 light-years from the supermassive black hole powering the quasar, the jet of high-energy particles provides astronomers with information about the intensity of the cosmic microwave background radiation 12 billion years ago.
