Tevatron turned in a record|
run following the shutdown
Fermilab's Main Control Room (Click on image for larger version.)|
The Tevatron hit some bumps in the road over the weekend, but the
ride has been a good one since the shutdown ended. On Monday,
Jan. 17, the Tevatron set another initial luminosity record
at 1.05x1032 cm-2s-1 in store #3925,
then came close with 1.04E32. A record rate of antiproton production
contributed to the luminosity record, and the integrated luminosity for
the week of Jan. 17 was the third best ever for the Tevatron.
"These small steps demonstrate our progress. They are not due to major
breakthroughs," said Accelerator Division head Roger Dixon. "But
they show that we're on the correct slope for continuing to improve
the luminosity of the Collider."
An improved stacking rate in the Accumulator contributed to the luminosity
boost following the shutdown, since antiprotons are a key to luminosity.
With the Recycler now playing an important role in storing antiprotons,
the Accumulator's average stacking rate improves as antiprotons are
periodically transferred to the Recyler. The Accumulator now can
spend more time stacking with a small stack where the rates are higher.
"Another factor is the Tevatron reliability that results in stores lasting
longer," Dixon said. "This gives us more time to stack antiprotons for the
The post-shutdown surge wasn't crisis-free: major power outage originating
with Commonwealth Edison on January 3 shut down operations for three days.
"The whole Division performed remarkably well," Dixon said. "You can't just flip
a switch and turn the Tevatron back on after a power outage. Many things happen
when the power goes off, not the least of which is warmup of the Tevatron
cyrogenic magnates. Cooling the cryogenic systems back down takes time.
Nevertheless we managed a very rapid startup that beat our intitial
estimates by several days.In another incident last week a vacuum circuit
breaker in the Main Injector failed spectacularly. This event had to
potential to cause a much longer downtime than we actually experienced
due in large part to the Operating and technical support staff in both
the Accelerator Division and in FESS responding quickly and effectively.
The next two challenges for the Division are continuing to increase the
stacking rate in the Accumulator and commissioning the electron cooling
system in the Recycler. Dixon said the goal for electron cooling is to
circulate an electron beam in the Pelletron in February, and then to
introduce the electron beam into the Recycler in March.

Major players put Chicago on map for grid computing
by Howard Wolinsky
A new trade association backed by major computer industry companies is being
formed here to promote grid computing.
Grid computing is a technology that enables users with diverse programs
and operating systems to share computer processing, storage, data and
software across networks. The trade association's aim is to move
grid computing out of the ivy tower and into corporate towers.
Hewlett-Packard, IBM, Intel and Sun Microsystems today will announce they are sponsoring the Globus Consortium to create open standards for grid computing, a technology developed by Argonne National Laboratory here and the University of Southern California. The Globus Toolkit, which includes software for sharing resources and security, was built to help scientists and corporations that want to develop their own secure grids. The system was honored in 2003 with a Chicago Innovation Award, presented by the Chicago Sun-Times and Kuczmarski & Associates.
Friday marked the first attempt to operate the NuMI neutrino beam, and it was a spectacular success. The MINOS experimenters observed a neutrino event on the fourth pulse of the beam with the focusing horn on. It didn't take many protons from the Main Injector to produce this event. During routine operation of MINOS, the Main Injector will deliver about 50 thousand times as many protons to the NuMI target every hour as one of those initial pulses.
Many more neutrino events were collected by the end of the weekend, fulfilling the final milestones for the 6-year long NuMI project. Greg Bock and the many people who worked on the NuMI project can be very proud of what they have accomplished. It was as difficult and important a project as anything done in the scientific world over the last few years.
Fermilab is the primary center for neutrino physics with accelerators, with the MiniBooNE experiment operating in the Booster neutrino beam and the MINOS experiment in the long-baseline NuMI beam. From the earliest days of the laboratory, Fermilab neutrino experiments have been in the forefront of the field. We look forward to great results from MiniBooNE and MINOS in the years to come.

Neutrino Video Installation
The ThreeWalls Gallery in Chicago is showing until January 29 the video
installation "BALDINO-NEUTRINO" by New York based artist Phyllis Baldino.
The room-sized installation is based on video filmed at CERN, including
footage inside the SPS tunnel. During the continuously running video, the
artist pretends to become a neutrino herself and take the 2.5-millisecond
journey 454 miles to Gran Sasso, Italy. ThreeWalls is located in the West Loop at 119 N. Peoria
#2A, Chicago. Take CTA Blue Line to Grand or UIC/Halsted. Gallery Hours:
Tues - Sat 12 noon - 6 pm. Admission is free.

Free Introductory Tai Chi Class
A free introductory
Tai Chi class will be offered in the Recreation Facility on Friday, February
18 from 6:30 AM to 7:15 AM. If there is adequate interest in
Tai Chi Classes at this time, Recreation will schedule an eight week session, same
time and same day of the week for a cost of $60.00. Registration for the
free class can be made by calling the Recreation Office at X5427 or X2548.
You must pre-register. You do not need to be a member of the Recreation
Facility for this introductory class, however, you will need to be one to
participate in the scheduled 8-week session. Deadline to register for this
class is February 11.
