New Zealand Earthquake Rocks Tevatron, Gently |
||

|
Early this month, a magnitude 7.9 earthquake in New Zealand sent a shiver through the ground that might have affected the Tevatron if it had been running. "We could watch in real time the waves go through the ground under us. If it had been bigger it would have been a problem," said Todd Johnson, Tevatron Operations Specialist.
Earthquakes are usually too small and too far away to make much difference to the running of the Tevatron. But the shockwaves from an earthquake could make the beam stray significantly, sending the stream of high-energy particles through a piece of delicate equipment. "It can be very tricky. A millimeter is a huge motion for a 2-km (diameter) machine," Johnson said. Movement in the ground causes the magnets responsible for focusing the beam to move with respect to one another. This results in the characteristic signature of a passing earthquake, where clumps of particles that typically stray from the stream (called "losses") appear to "breathe," getting periodically larger and smaller. "The quake itself can take tens of minutes to pass, and that can give us time to warn the experiments that losses could become higher than they would like," Johnson said.
It was first discovered that the Tevatron could feel earthquakes three years ago, when a magnitude 8.0 in Alaska sent too many "lost" particles hurtling into the superconducting magnets, overheating the magnets and causing the accelerator to automatically shut down. Although software allows the Tevatron to correct its beam's orbit every thirty seconds, that time period is too long to compensate for constant earthquake motion. New software is in the works for decreasing the correction time.

The Herald Sun May 26, 2006: Physicists talk proton smashing at Duke DURHAM -- It may not be measurable in teraelectronvolts, but a buzz of excitement was evident among physicists from around the world who gathered at Duke University for a weeklong conference that ended Friday. It was the first time the annual Hadron Collider Physics Symposium was held at Duke and it was an auspicious one as physicists prepare for the opening in Switzerland of a very large demolition derby for some very tiny bits of matter.
The Large Hadron Collider, as the facility being built near Geneva is called, generated a lot of discussion during the symposium, said Duke physics professor Ashotosh Kotwal, who chaired the conference. Physicists are already devising experiments that they hope will prove or disprove various theories, he said.

| "Gathering Storm" chair will speak tonight at Fermilab | |
|
|
| How can the United States maintain its competitive edge as foreign nations make advances in science and engineering? Find out tonight at 8 p.m., when Norman Augustine, former Lockheed Martin CEO and chair of the National Academies report, Rising Above the Gathering Storm: Energizing and Employing America for a Brighter Economic Future, speaks in the Ramsey Auditorium.
Rising Above the Gathering Storm received broad attention and inspired President Bush to announce the American Competitiveness Initiative in his 2006 State of the Union address. Mr. Augustine will discuss how the report and the initiative outline a plan for the United States to stay on the leading edge in science and technology. The event is free and open to the public. For tickets, call Kathy Johnson at ext. 2787. |

'Shop and Share' weekend for the LaFleur family - last day! John LaFleur was a Fermilab electrician who passed away March 26 as a result of complications from a brain tumor. He is survived by a wife and three children and had not worked at Fermilab long enough before his death to receive a pension. Now you can help his family when you shop for groceries. This is the last day of the 'Shop and Share' weekend dedicated to the LaFleur family at Jewel - Osco. Jewel -Osco will donate 5 percent of any purchase made on May 29, 30, or 31 to the fund if you present a "Shop and Share Identification Slip" with the Lafleur Family Fund and ID # at the cash register. Connie Crome has these coupons in Wilson Hall, 5th Floor East, and a stack of them are on the Counter at Sue Quarto's desk at Site 38. Please feel free to distribute as you are able. They may be copied, but must be cut down to the original coupon size for use. You may also call Greg Gilbert at ext. 6835, cell # 404-0106, pager # 722-7609, or email gilbert@fnal.gov to get coupons today before it's too late.
