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 next store."

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.

From Chicago Sun-Times, January 24, 2005
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.

Director's Corner
Good Morning!
Mike Witherell

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.

Accelerator Update

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.
