Tevatron Performance Achieves New Records|
On Sunday, August 10, the peak luminosity record at the Tevatron saw a
10 percent increase, bringing it to 4.9E31 cm-2sec-1. The
success coincided with a record number of antiprotons traversing the collider
detectors at the energy of 980 GeV.
Accelerator experts Doug Moehs and Elvin Harms attributed the latest increase
in accelerator performance to a number of changes, including the removal of
a diagnostic titanium grid in the beamline between the antiproton accumulator
and the Main Injector accelerator. The total integrated luminosity for last week
was 6.8 inverse picobarns (pb-1), bringing the fiscal year total to
215.6 pb-1. The FY03 goal is 225 pb-1.
International Theme Highlights Opening of Lepton-Photon 2003|

Fermilab Director Michael Witherell declared that the longstanding international nature of particle physics
is "the only way to pursue our science," as he welcomed nearly 800 scientists
from around the globe to the opening of
in Wilson Hall's Ramsey Auditorium Monday morning. Peter Rosen of the
U.S. Department of Energy's Office of Science reinforced the message, and
drew warm applause, by issuing a welcome on behalf of DOE in seven
languages-English, Japanese, German, French, Italian, Russian and Spanish.
The opening day activities included the presentation of the N. N. Bogolubov Award from the Joint Institute for Nuclear Research in Dubna, Russia to Yoichiro Nambu, the Harry Pratt Judson Distinguished Service Professor Emeritus, of the Department. of Physics at the University of Chicago and the Enrico Fermi Institute.

ITER is Focus of Fusion Advisory Committee Meeting
"ITER is more than just fusion energy sciences; it may well be the path forward for all of large-scale truly international science collaboration. So we have a lot at stake in this process." - DOE Office of Science Director Ray Orbach
The multi-national collaboration to build the International Thermonuclear Experimental Reactor (ITER), and the project's impact on the domestic fusion program, was a main topic of discussion at a July 31 - August 1 meeting of the Fusion Energy Sciences Advisory Committee. As at a recent High Energy Physics Advisory Panel (HEPAP) meeting (see FYI #102), other major topics included the need to develop program performance measures and the need for a consistent set of criteria, spanning all fields of science, for building large-scale facilities.

Warrenville prefers STAR station to extending Eola Road
By Beth Snellerand Jake Griffin Daily Herald Staff Writers
Building a depot for a suburban transit system could deter DuPage County from extending Eola Road north through Warrenville, some Warrenville aldermen say.
The Warrenville City Council hosted an informal discussion Sunday with community leaders to explain why the city is involved with plans for the STAR (Suburban Transit Access Route) Line.
STAR is a proposed rail system devised by Metra, RTA and Pace to move residents from suburb to suburb and to O'Hare International Airport. Plans for the system are contingent on federal funding, which local officials will seek this fall.
This week we are hosting the 21st International Symposium on Lepton and Photon
Interactions at High Energies. This is the largest international conference
in our field this year, and it is a chance to share with our colleagues around
the world new results in particle physics.
Here at Fermilab we are doing research at several of the frontiers of particle
physics. The greatest interest from our field is, of course, on the Tevatron
collider program. Yesterday afternoon at about 5 pm, I was in the Main Control
Room as they injected an antiproton-proton store with record luminosity,
an average of about 4.9E31 cm-2 s-1, about twice the best done a year ago. For the fiscal year just finishing, we will have collected about 240 pb-1, compared to about 100 pb-1, the best year of Run I. The experiments are running very efficiently, analyzing the data, and producing new physics results. The talks on Tevatron physics at this conference mark the start of the torrent of new physics results from CDF and D0 that will continue for the next several years.
- Tevatron store #2887 set new record for initial luminosity.|
-Tevatron also suffered two quenches, high losses, and RF problems.
- Operations established three stores during the last seventy-two hours. They delivered approximately twenty-eight hours and fifteen minutes of luminosity to the experiments.

Fermilab Science Demonstrations at the Field Museum|
On Wednesday, August 13 from noon to 4:00 p.m., Fermilab physicists will give
science demonstrations on electricity, magnetism, particle detection and
acceleration in the entrance hallway of the Field Museum. The demonstrations will be
appropriate for all ages. This event is a public outreach activity for the Lepton Photon conference. For more information, contact
Ben Kilminster or Herman White.
Tom Peterson will host a butterfly walk on Wednesday, August 13 at noon at Site 70 on Wilson Street.
The walk will be short and easy along the road and driveway looking at the numerous butterflies, which lately have included Meadow Fritillaries.
No signup is necessary. If you have questions about the walk, call x4458 or email email@example.com.
