Doubling-Time for Run II: The Future of Luminosity | ||
| ||
|
Earlier this summer, Fermilab users from all areas of the lab gathered in the Atrium to celebrate a major milestone. The achievement of one inverse femtobarn of integrated luminosity in the Tevatron started a new chapter in Fermilab science, and prompted considerable discussion about when two inverse femtobarns would be achieved. "Staying on the design curve becomes ever more difficult as the slope grows increasingly steep," said Head of the Accelerator Division Roger Dixon. "Up to now all of the upgrades we have implemented have worked at planned, but the changes are becoming more complex as we work our way through the upgrade plan."
Luminosity is a measure of the brightness or intensity of the particle beams in an accelerator and determines the number of collisions that occur when the beams intersect. Peak luminosity is defined as the number of collisions that occur during the first few minutes after the protons and antiprotons are injected for a store, and integrated luminosity is calculated by adding together the total number of collisions that occur over time. Individual stores last until the luminosity drops to a level where it is no longer useful for the experiments, or until it is lost due to a problem in the Tevatron. Ideally a store begins with a high peak luminosity followed by a long, slow decrease in luminosity until collisions are occurring at a rate that is no longer useful to the detectors.
Although luck has something to do with how well a particular run goes, the design curve is determined by the calculated impact the various upgrades that are planned for the Collider will have on the luminosity curve. "It is a constant struggle to continue increasing the slope of the design curve," said Dixon. "Electron Cooling and an antiproton stacking upgrade are two of the major upgrades remaining. They are both risky, but if they work, they will keep us on the curve. The recent success with cooling antiprotons with an electron beam gives us a good indication that electron cooling is going to significantly increase the luminosity we can deliver." So far, Fermilab has stayed right on the design curve, and a total of two inverse femtobarns are expected in about one year. By that time, the rate of delivering luminosity should be approaching the rate necessary to achieve eight inverse femtobarns by 2009.
*Kim invites the Fermilab community to preview and critique her upcoming Aspen public lecture on 21st-century particle physics this afternoon from noon until one p.m. in 1 West. |

Fermi Intern Unites Two Fields, Advocates Science | ||
| ||
|
Victoria Moeller is having a great summer. Working with Peter Shanahan on the MINOS experiment, the third-year undergrad at Michigan State says she has to keep her mind focused on her work to stay immune to the "magic" of Fermilab: "Sometimes I'll be driving up to Wilson Hall and think, 'I can't believe I work here,'" she said. "Every place you go has its advantages, but this is like the Ivy League of internships."
Moeller came to the lab through the Internships for Physics Majors (IPM) program, and was placed in the Particle Physics Department analyzing data from MINOS. "I mentioned particle physics and neutrinos in my application essay," said Moeller. "Now I'm learning everything I could possibly absorb about neutrino beam physics." Her work involves extensive use of new technologies for analyzing data, and she greatly appreciates the opportunity to experience "all of the components of being able to see what's going on in the detector."
Her interests, however, extend well beyond the purely technical. Double majoring in Physics and Political Science/Public Policy, Moeller wants to promote science on a more public scale. "I hope to stay involved in science advocacy," she said. "If I decide I don't want to be a physicist, I'd like to be someone who actually understands the science working on funding and science education."

From Interactions News Wire, August 10, 2005 New Director for CCLRC Particle Physics Dr. John Womersley will join the CCLRC as Director of Particle Physics. Dr. Womersley, who will start work on 1 October and is based at the Rutherford Appleton Laboratory, was previously working at Fermilab in the USA. |

Roads and Grounds Thanks Dedicated Summer Students | ||
| ||
|
The Fermilab Roads and Grounds Section held their annual picnic in the Village on Wednesday, August 10. The department organizes the event at the end of each summer to thank its summer students, who perform tasks ranging from watering trees to mowing fields to general maintenance of the lab.
"Summer is a busy time for us," said Mike Becker, the Roads and Grounds supervisor. "The students are a big part of our summer workforce, and we're grateful for all the work they do." The Roads and Grounds summer program hires high school and college students to supplement the department's regular staff. "The quality of students that we get is just remarkable," Becker said. "There are seven students working with Roads and Grounds this year, as well as two others working with the FESS Engineering Group." This summer's severe drought presented a particular challenge to Roads and Grounds. The students spent much of their time watering trees and other plants to maintain Fermilab's ecosystems. "They kept our trees alive," said Randy Ortigiesen of the FESS Infrastructure Management Group.
Gerry Garcia, an incoming freshman at the University of Illinois Urbana-Champaign, has had such a good experience with the Roads and Grounds summer program that he has returned for three years running. "My parents both work at Fermilab, and I like the environment here. It's a fun place to work," he said. Jake Whiteaker, who is entering his senior year at Somonauk High School, agreed, saying, "It's my first year in the program, but I'd probably come back."
