Fermilab in for the Long Run

Cheer for Fermilab employees and friends this Sunday, October 22, as they compete in this year's Chicago Marathon. "Chicago is a wild event," said runner Eugene "JJ" Schmidt of CDF. "To run a race with thousands of people is incredible--you are surrounded." Schmidt is part of the Fermilab running team "U Can Run Too," which will compete in the recreational co-ed division of the Chicago Challenge, a three race series. Sunday's marathon is the last race. The team is currently tied for first place in their division. "If we bring back a trophy," said Schmidt, "it will be a fine thing."

Organizers of the marathon expect 1.5 million spectators. An energetic crowd helps a runner finish the race. "After about the 20th mile mark, it becomes a mental exercise," said Schmidt. "It is nice to have the crowds to feed off their energy."

An informal group of Fermilab runners meets at noon on Mondays, Wednesdays and Fridays to run around the Tevatron ring. Regular runner Steve Mrenna, Computing Division, completed his first marathon last year in Chicago. "It's amazing to see 40,000 people who are as crazy as you are," Mrenna said. He added, "Maybe it's comforting." Mrenna finds the goal of a marathon helpful in his work. "It helps to have challenges," he said. "They keep you sharp and focused."

SciBooNE's SciBar detector zipping along at light speed
Rick Tesarek (left) and John Cornele inspect the frame for the SciBar detector.
Quick-moving experiment SciBooNE is half-way through construction of their main detector, SciBar. The detector's frame, custom designed by Ed Chi, PPD mechanical department, is completed and paneled to be light-tight. In the next step, SciBar subdetector manager Hidekazu Tanaka, Kyoto University, will oversee installation of the 64 scintillator layers. Scintillator material emits light when a charged particle flies through. That light will be picked up by optical fibers and photomultipliers and recorded by the detector's computers. Any outside light will skew results.

For the light-proofing, John Cornele, PPD mechanical technician paneled the detector frame with plywood. "Normally this would be done with metal," said Rick Tesarek, of Fermilab, SciBooNE project head. "But this is less expensive and works just as well. We're giving the tax payers good value for their money."

Work on the paneling began Monday, October 9, and is expected to be completed next week. A live webcam, set up by Visual Media Services, is tracking the project's progress. Java Runtime users can view it at http://vms-webcam01.fnal.gov. Upon completion of the detector, VMS will compile a time-lapse video to show the work from start-to-finish.

In the News
CERN Press Release, October 19:
New Experiment to Investigate the Effect of Galactic Cosmic Rays on Clouds and Climate

Geneva, 19 October 2006. A novel experiment, known as CLOUD (Cosmics Leaving OUtdoor Droplets), begins taking its first data today with a prototype detector in a particle beam at CERN[1], the world's largest laboratory for particle physics. The goal of the experiment is to investigate the possible influence of galactic cosmic rays on Earth's clouds and climate. This represents the first time a high energy physics accelerator has been used for atmospheric and climate science.

Road to the ILC
reference design
This column is written by Barry Barish, director of the Global Design Effort.
The GDE Schedule to complete the Draft Reference Design Report and Preliminary Costing.
The next big goal for the Global Design Effort is to produce an ILC Reference Design Report (RDR) that will include Preliminary Costing. We are systematically working toward this goal, and have now progressed far enough to set a realistic schedule. In recent columns, I highlighted some of the evolution of the baseline resulting from either technical advances from our R&D program or from cost to performance optimization. Several more studies are underway, and we expect to evaluate these in the coming weeks, especially at the upcoming Valencia GDE meeting in November. Following that meeting, we will make some final decisions for the RDR and begin the process of concluding this phase of the design effort. Our plan is to release the draft Reference Design Report and Preliminary Costing on the time scale of the GDE Meeting in Beijing in February 2007.

The ILC baseline configuration (BCD) developed last year defined the major parameters and concepts for the ILC. This year, through an orderly change control process, we have evolved that design concept. The next big step is to create a reference design, in which we will define in detail the technical parameters and components that make up each of the subsystems in the ILC baseline. The main linac, for example, is made up of superconducting RF cavities, cryomodules that house the cavities, low level and high level RF, magnets and so on. For each of these sub-elements, we are determining the technical and performance parameters, and itemizing the components in order to make a first estimate of the costs. This process will give us a complete design concept but with only a few engineering drawings. The RDR will provide guidance for our R&D program, motivate industrial studies and be the basis for the engineering design needed to make a project proposal. For the RDR, we have deferred consideration of those potential changes that will require significant engineering or industrial studies to evaluate.

A Taste of Taiwan
CDF physicists are organizing a get-together with Taiwanese food and music on Thursday, October 26, from 6:30 p.m. to 9:00 p.m. in the Kuhn Barn. "There will be free Taiwanese food," said organizer Shin-Shan Eiko Yu. "We will also provide some travel information, play traditional Taiwanese music, and display news clips about Taiwan."

English country dancing
English country dancing will continue at Kuhn Barn, and is changing to meeting the first Sunday afternoon of the month. It is not meeting in October, and will take place next on Sunday, November 5, at 2 p.m. Please contact folkdance@fnal.gov or call 630-584-0825 or 630-840-8194.

NALWO Fall Luncheon
There will be a NALWO fall luncheon Monday, October 23, from 11:30 a.m. to 1:30 p.m. at Chez Leon in the Users' Center. Join lab women (guests, visitors, users and employees) and help plan interesting activities for the coming season. Please bring a dish to share: casserole, salad, side dish, dessert, or whatever you choose. For additional information, contact the Housing Office at 630/840-3777 or housing@fnal.gov; or call Rose Moore at 630/208-9309.

GSA Halloween Party
GSA will have its annual Halloween party in the Kuhn Barn on Friday, Oct 27 at 7:30 p.m. Come, hang out and enjoy snacks and beverages and candy. You can wear your favorite Halloween costume for a shot at a prize and join in the pumpkin carving contest! RSVP to kendallm@phys.columbia.edu.

Village Power Outage
Maintenance has scheduled a Village power outage for Saturday, October 21, from 7:00 a.m. to about 4:30 p.m. The outage will affect all Village labs and housing. Please plan accordingly.

Lost and found
An employee recently found a cardboard carton on site on Batavia Road. The carton has a label that says "PO 183341, qty 1 ea, Item# 3050002, Description Left Cart Door 5-B, Size 530 x 390 x 120 (mm)." It possibly fell off a contractor's truck. If this belongs to you, or someone you know, contact Tim Smith at tsmith@fnal.gov.
