Employees, Users and Contractors
Invited to Attend NuMI/MINOS Dedication on Friday | ||
| ||
|
Fermilab employees, users and contractors are invited to attend
the dedication ceremony for
the NuMI/MINOS experiment in Ramsey Auditorium at 2:30 p.m. on Friday, March 4.
Speaker of the House Dennis Hastert and DOE Office of Science Director Ray Orbach
will formally launch NuMI/MINOS.
A lab-wide party, sponsored by the URA,
will be held in the Atrium from 3:30 p.m. to 6:30 p.m., following the Auditorium
ceremonies.
Portions of Ramsey Auditorium will be reserved for MINOS collaborators, NuMI project staff, and special guests that include congressional staffers, DOE officials, members of the press and other VIPs. Invitations have already been sent via email to the people who will have reserved seats in the auditorium. Ushers will be on hand to direct people to their seats. Overflow seating will be available only after the auditorium is completely full. All attendees should be seated in Ramsey Auditorium by 2:15 p.m. A slide show on the history of the project, produced by Visual Media Services with the assistance of Cat James, will begin at that time. Employees are strongly encouraged to car-pool from other areas of the site, as parking will be at a premium. The Horseshoe will be completely reserved for participants in the ceremony. Additional parking will be available at the Lederman Science Center. - Elizabeth Clements

February 28 - March 2 - During the 48 hour period Operations established one store that provided approximately 29 hours and 15 minutes of luminosity for the experiments - NuMI and Pbar take beam - Booster has RF problems - TeV quench loses store before it's established - H- Source suffers arc current problem

From PhysOrg, March 1, 2005 Fermilab experiment to beam neutrinos through Dairyland In an effort to pin down the elusive nature and qualities of one of nature's most intriguing subatomic particles - the neutrino - scientists at Fermi National Accelerator Laboratory, or Fermilab, in Illinois will soon send a beam of the ghostlike particles coursing through subterranean Wisconsin to a detector deep in a mine in northern Minnesota. The goal of the $170 million project is to help scientists gain some accurate measurements of a particle that has practically no heft. read more |

Muons Mark the Top Quark at CDF | ||
| ||
|
Thirty five miles west of Chicago two detectors with the
cryptic names CDF and DZero attract hundreds of scientists
while recording the highest energy collisions on Earth. In
the heart of Chicago a building known as the John Hancock
Center attracts scores of tourists with its elegant
appearance. Both unique masterpieces, they have one
unmistakable difference: the skyscraper is massively bigger,
and much taller, than the detectors.
Mass is a familiar concept in everyday life, but oddly it is one of the least understood properties in particle physics. Matter in the universe appears to be made up of fundamental building blocks called quarks and leptons, but the origin of the masses of the building blocks remains a mystery. Therefore the top quark, more than forty times heavier than any other quark or lepton, could be playing a special yet unknown role in physics. Highly unstable, top quarks decay into one W boson (the particle carrier of the weak nuclear force) and one b-quark. The b will bind with other quarks leading to a jet of particles, and the identification of these rapidly escaping b's is the key to detecting top quarks. The CDF Collaboration now measures the production rate, or cross section, of top-antitop pairs at the Tevatron by using a technique that spots b's by looking for muons in jets. A number of b's in fact will undergo a semileptonic decay, a type of decay which often leads to the production of a muon. Counting the number of events containing one W along with muons in jets, in excess of those expected from background sources, yields a determination of the top production probability. The result, a cross section of 5.2+/-2.7 pb, gives physicists at CDF yet one more tool to test the properties of top quarks, the skyscrapers of all elementary particles. | ||
