A well-oiled machine:
AD's run coordinators

From left: Salah Chaurize, Brian Drendel and Cons Gattuso make sure the accelerators are running.

Salah Chaurize sits at his second-floor desk in the west Booster tower, scrutinizing real-time accelerator reports on his computer. He halts at one graph, where a green line indicating Tevatron beam intensity has dropped to zero. The phone rings at the next desk, where Brian Drendel picks up, listens, and responds cheerily, "Well, that's not fun." It's time to make a new plan.

The two men, along with third team member Cons Gattuso, make up the Accelerator Division's Run Coordination team. Led by Drendel, they make sure that each of the lab's nine accelerators and three major beam lines run efficiently within the scheduling demands placed on them every day. "These guys have one of the most difficult jobs at the lab," said AD division head Roger Dixon.

Possibly the team's greatest challenge is to balance the current level of production with requests from physicists for continual improvement, or studies, which could affect the accelerators' performance. "If we do studies for four hours, that's four hours the colliders may not be taking data," said Gattuso. "But if we can increase performance with those improvements, then that's worth it." All three team members have experience working in operations at Fermilab, which helps them decide which maintenance needs are critical. "You like to get to a point where you can attack several problems at once," said Chaurize. During a recent two-day accelerator shutdown, the team approved over 100 maintenance and improvement jobs.

Because the accelerators operate around the clock, so does the team. Each member is constantly within reach of his cell phone, and Chaurize and Drendel even admitted to checking the accelerator's status on their laptops during the Super Bowl. But their commitment isn't unique. They attribute their success to the system experts, technicians and machine operators who work day and night to get the jobs done in the accelerator complex. "It's quite an honor to be at Fermilab," said Chaurize. "It's the caliber of the individuals that makes the place."

Photo of the Day

Sunshine, moonshine: AD's Josh O'Connell took this picture with his cell phone on his way to work last week. "It was really cool to see the moon setting directly in front of me and the sun rising directly behind me in the rearview mirror," he writes.

Chinese finger puzzle?

Dear FT:

In response to yesterday's "Photo of the Day": Tractricious is the adjective form of Tractrix. The name of the sculpture derives from the ''pulling in'' that occurs when a right circular cylinder is twisted uniformly around its axis.

Randolph J. Herber,
Computing Division

The photographer responds:
Thanks a lot for this; I never thought to look for other forms of the word. All these years my best analogy was a Chinese finger puzzle.

Tom Nicol,
Technical Division

Solving the Fermilab 'mystery'

BATAVIA - Eight-year-old Lauren Bloomfield tried to race gravity Sunday.

She lost.

"No one can win," Lauren's friend Lyndsey Notaro reassured her.

The pair from Hinsdale came to Fermilab in Batavia to its annual open house event, offering hands-on science experiments, tours and various lectures and demonstrations.

One of the hands-on experiments - often popular among children - was the gravity accelerator. A ball is placed atop a spiral slide and participants run around the contraption a number of times, trying to race the ball.

Director's Corner


Director Oddone at the Temple of Heaven (Tiantan).

Last week I was in Beijing attending the closing days of the joint meeting of the Global Design Effort (GDE) and the Linear Collider World Wide Study of Physics and Detectors (BILCW07), the meeting of the International Linear Collider Steering Committee (ILCSC) and the meeting of the International Committee on Future Accelerators (ICFA). World-wide collaborations do carry an acronym burden!

Coincident with the Beijing meetings, the GDE achieved a major milestone in the long path to develop the ILC: the conclusion of the Reference Design Report and associated cost estimate. This was a major accomplishment for the GDE. In the year and a half of its existence the GDE under Barry Barish's leadership has managed to bring together the many groups working on ILC across the world to produce a common design that reflects many hard choices. The GDE has analyzed the design thoroughly to achieve cost effective solutions while maintaining the performance requirements of the machine. We should all be proud of the important role that Fermilab has played in helping to bring the RDR and cost estimate to conclusion. The RDR and cost estimate can now be used by policy makers in the many agencies across the world to decide the next steps for the ILC development.

For those of us who have been visiting Beijing since the 1980s, seeing Beijing today is astonishing. To observe its development is to believe that nothing is impossible. In twenty years Beijing has gone from a sea of bicycles and a population dressed in Mao suits to a modern city full of high-rise buildings and jammed freeways. The development of scientific institutions like the Institute of High Energy Physics (IHEP) is equally remarkable. Starting with only some talented and devoted scientists in the 1980s, IHEP today is a thriving institution. It is commissioning a world class collider the tau-charm factory and associated detector BESIII, it runs x-ray beamlines, it is building the Daya Bay neutrino project - the most ambitious neutrino reactor experiment in the world - and it is about to launch its second campus in Southern China to build a Spallation Neutron Source. Over the years the US labs including Fermilab have helped the development of IHEP. This was recognized by Director Hesheng Chen in his opening remarks: Collaboration is the key word in particle physics. Looking to the past, we can see no successes in the field could have been achieved without collaboration.... Looking to the future, we have reason to believe that collaboration will be again the basis for ILC success.

You can help stop local shortage by giving blood, Feb. 19-20

The Heartland Blood Center is facing shortages, and soon you'll have a chance to help. You can donate blood at Fermilab February 19 and 20, from 8 a.m.-2 p.m. in the Wilson Hall Ground Floor Training Room. Appointments are suggested, but not required. To make an appointment, visit the ES&H website.

New mileage reimbursement rate
The Internal Revenue Service and the General Services Administration have issued the 2007 standard mileage reimbursement rates as 48.5 cents per mile, effective February 1, 2007. Keep this in mind when planning work-related travel.

Wilson Street Bridge to Close
If you commute through Batavia, please note that the Wilson Street Bridge will be closed Thursday, February 15, through Friday, March 2. You can read more about the bridge construction and detours on the Bridging Batavia Website.

Reduction in Your Long Term Disability Insurance Premium
If you've noticed an increase in your net income in your paycheck, it's because less money is being deducted for your Long Term Disability (LTD) insurance premium. Fermilab has renegotiated a lower insurance premium in the new contract with the insurance carrier. Each participant enrolled in the LTD insurance plan will receive a memo with all of the details. If you would like to access the details immediately, please click here.

NALWO Slide presentation
On Thursday, February 15, Susan Kayser of NALWO will hold a travelogue of Egypt slide presentation from noon until 1:30 p.m. in 1 North of Wilson Hall. Lab women, guests, visitors, users and employees are invited. Taxi service is available from the Village by calling x4225. Please bring your own sack lunch or snack. For additional information, contact the Housing Office at 630-840-3777 or housing@fnal.gov, or call Rose Moore at 630-208-9309.
