Discussion on underground science programs - today

Today, the U.S. House of Representatives Science, Space and Technology Committee will host a roundtable titled Department of Energy Underground Particle Physics Programs at Fermilab from 10 a.m. to noon. The roundtable will examine the future of the DOE's underground particle physics program, specifically regarding the future of the Deep Underground Science and Engineering Laboratory, known as DUSEL. Fermilab employees and users are invited to watch a live video broadcast of the discussion in Ramsey Auditorium.


Al Legan retires after 42 years

There will be a farewell party for Al Legan today at 11:30 at Riverview Banquets in Aurora.

When Al Legan arrived at Fermilab 42 years ago, most of the laboratory’s business was conducted out of the houses that had made up the small farming town of Weston. He retires on Oct. 7.

Legan was unemployed and going to night school when he saw a newspaper ad indicating the laboratory was hiring. He drove up from Joliet to check it out.

“There was really nothing here yet,” Legan recalled. “It was just a bunch of holes in the ground.”

He was hired as a machinist and has since worked as a technician and in various other positions. He currently holds a position in engineering in the Accelerator Controls Department of the Accelerator Division.

Legan thought he would work at the laboratory for about five years. He was wrong.

Parking changes - Sept. 29-30

Starting in the evening of Thursday, Sept. 29, evening and lasting until the morning of Saturday, Oct. 1, morning, the parking spaces on the east and west sides of Ramsey Auditorium will be closed. Tents will be set up in the space to accommodate employees and users attending the Tevatron shutdown celebration. Parking cones will mark off the restricted areas. The 17 parking spaces directly behind the auditorium will remain open.

Long live the Tevatron

As the Tevatron closes down, the data analysis continues, but there are already many areas in which the experiments have delivered results of enduring importance. Chris Quigg surveys some highlights.

A quarter-century of experimentation is coming to a close at Fermilab's Tevatron collider, a pioneering instrument that advanced the frontiers of accelerator science and particle physics alike, setting the stage for the LHC at CERN. The world's first high-energy superconducting synchrotron, the Tevatron served as the model for the proton ring in the HERA collider at DESY and as a key milestone towards the development of the LHC. In its final months of operation the Tevatron's initial luminosity for proton–antiproton collisions at 1.96 TeV averaged more than 350 inverse microbarns per second. The integrated luminosity delivered at 1.96 TeV approached 12 inverse femtobarns, with approximately 10 inverse femtobarns recorded by the CDF and DZero experiments.

Fermilab will chase supposed faster-than-light particles

From WBEZ 91.5, Sept. 25, 2011

Scientists at west suburban Fermilab are already working to scrutinize a potential scientific discovery widely believed to be impossible. European physicists announced last week they clocked something traveling faster than the speed of light. If true, the observation from the European lab CERN would turn much of physics inside out, as the speed of light is thought to be an absolute limit on how fast anything in the universe can travel.

The MINOS experiment at Fermilab may be the best equipped in the world to test CERN’s results, and its spokesman says they’re hopping to it.

“Obviously it’s a very high priority,” said Robert Plunkett. “Anything that makes a statement about the foundations of Einstein’s theory of special relativity, that’s one of the two underpinnings of all 20th century physics. So it has to be scrutinized and of course it’s urgent to attempt to reproduce the results as soon as possible.”

Result of the Week

Thank you from CDF

On October 13, 1985 at Fermilab, the Tevatron produced protons and antiprotons collisions inside the CDF detector for the very first time. It was a magical day for the few dozen people in the accelerator and CDF control rooms. Since that day, literally billions of matter-antimatter collisions took place inside CDF and then inside CDF and DZero. What was once novel is now routine – and routine at an unprecedented scale. The intensity of the beams gradually multiplied, thanks to the relentless efforts of the Tevatron accelerator physicists.

Friday at 2 p.m., after nearly 26 years of operation, a switch will be turned, ending the career of one of the most remarkably successful colliders ever in particle physics. The Tevatron collider established a brand identity for Fermilab and changed the physics landscape forever.

This program allowed CDF to achieve numerous physics highlights, including the discovery of the top quark, the precision measurement of the W boson mass, the observation of Bs mixing and the many limits set on potential new physics theories. Many of these results appeared in this column.

More than 3,000 physicists contributed to this rich program at one point in their career. Five hundred and thirty two students have received their Ph.D. in this program thus far, and the experiment produced a steady flow of more than 550 publications (and counting) in refereed journals. Now with a full dataset of 10 inverse femtobarns under the hood, CDF scientists expect to produce another hundred or so papers in the coming years.

The success of a program like this goes well beyond just those scientists involved. Twenty six years of fruitful operation requires a commitment from everyone here at the laboratory. From the accelerator scientists, to the technical staffs, the people in the business systems and those that maintain the laboratory infrastructure – each of you played a role in this success story. What a run it’s been – we should all be very proud of what we, as a team, accomplished. On behalf of all the members of CDF: Thank you, Fermilab. We did it together, and we did it very well!

Rob Roser and Giovanni Punzi,
CDF co-spokespersons
