Arts Series: Jazz Quartet Free Flight at Fermilab on July 31
Free Flight
Jim Walker & Free Flight
The music of Free Flight has turned jazz fans into classical buffs and classical audiences toward jazz. From Bach to Miles Davis to the Beatles, the range of musical influences exhibited by Free Flight is evident in every piece. Each composition blends together flavors of classical music, jazz, new age, and rock into a palatable whole. Listen for yourself when band leader Jim Walker brings his award-winning group to Fermilab's Ramsey Auditorium on Saturday, July 31 at 8 p.m., presented by the Fermilab Arts Series. Walker will give a pre-concert talk in room One West beginning at 7 p.m., free of charge. To preview a taste of what's in store, click here for a 20-second music sample (Real Player required).

Free Flight has appeared on The Tonight Show and at the Lincoln Center. Recent performances include sell-out concerts at the Interlochen Jazz Festival, Chautauqua, and the Hollywood Bowl. The group has produced eight recordings.

Tickets are $18 ($9 for ages 18 and under.) Call 630-840-ARTS (2787) weekdays from 9 a.m. to 4 p.m.

Our Readers Respond
Dmitri Denisov, of PPD and the DZero experiment, responds to the Sacramento Bee's "Scholars in Limbo" story that ran in the July 7 issue of Fermilab Today:

Dear Editors,

After reading the Sacramento Bee article "Scholars in Limbo," I want to share with you some disturbing numbers that represent how seriously the U.S. visa issue is affecting international cooperation. Since the summer of 2002, obtaining a U.S. visa has become one of the major issues for the participation of

almost 60 Russian scientists in the DZero Experiment at Fermilab. The average duration of waiting for a U.S. visa is about 5 months, with the shortest waiting period being one month and the longest waiting period being over 15 months. Only single entry visas are allowed with each entry period limited to two months, which makes planning visits to participate in detector operation and physics analysis practically impossible. The total time spent by the DZero collaborators waiting for U.S. visas has exceeded 20 years! After working over five years on the DZero experiment upgrade, Igor Vasiliev from IHEP(Protvino) has been waiting for a U.S. visa for over 15 months and has no clue as to when he will be able to continue his work at Fermilab. In addition to badly affecting current Fermilab experiments, the U.S. visa issue creates serious concerns about the participation of scientists from other countries in the future U.S. based programs.

In the News
From SDSS, July 19, 2004
Dark Energy, Inflation and Neutrino Mass News
Using observations of 3,000 quasars discovered by the Sloan Digital Sky Survey (SDSS), scientists have made the most precise measurement to date of the cosmic clustering of diffuse hydrogen gas. These quasars -- 100 times more than have been used in such analyses in the past -- are at distances of eight to ten billion light years, making them among the most distant objects known.

Director's Corner
Good Morning!
Mike Witherell
Mike Witherell
I was over in the Main Control Room Friday around 11:30 to watch the collider shot. It was a "mixed pbar" shot, using antiprotons from both the Accumulator and the Recycler. Enough antiprotons were stored in the two rings that if the shot worked it was going to be a record. They were swinging for the fences, and a lot of extra people gathered in the control room to watch.

People watched with anticipation as the experts supervised the intricate choreography among the four accelerators (Accumulator, Recycler, Main Injector, and Tevatron). Finally, as the beams were brought into collision, it became clear that it had all worked perfectly. We celebrated a record store of over 1032.

At the start of 2004 we were still coming out of the shutdown and the record luminosity was still below 5x1031. If somebody had told me then that before the annual shutdown we would hit 1032 luminosity using antiproton transfers from both antiproton rings, I would have thought them crazy. It has been an exceptional year.

Another reason to celebrate: the Linac and Booster were able to deliver a record 1019 protons to MiniBooNE last week.

It is a great year for the Fermilab accelerators, and it will lead to some great physics results in the year ahead.

Accelerator Update
July 16 - July 19
- The Tevatron achieved the second best weekly integrated luminosity, 16 inverse picobarns
- A new initail luminosity record of 103.43 E30.
- Operations established 3 stores during the last seventy-two hours.
- They delivered approximately sixty-one hours and forty-five minutes of luminosity to the experiments.

New Performance Review Form
Lab Service has posted a new performance review form that is a plain Microsoft Word document. It does not contain protected form fields. It may be used by people who are having problems using the form fields. It can also be opened by people who use OpenOffice or StarOffice. The new form is available online. If you have any questions contact Cindy Crego at x3278 or crego@fnal.gov

Attention Fermilab Users:
2004 UEC Committee Elections
