Witherell Addresses Budget To All Hands on Thursday
Director Michael Witherell will discuss "The Budget and Prospects for the Future" at three All-Hands meetings on Thursday in Ramsey Auditorium. The three sessions will be organized alphabetically by the last names of employees: A-G at 10 AM, H-O at 1 PM, and P-Z at 3 PM.

Fermilab Hosts Blood Drive In Wilson Hall Next Week
Blood Donors
Fermilab's top blood donors prepare for next week's blood drive. From left, Hans Jostlein (51 pints), Phil Schlabach (51 pints), Elvin Harms (53 pints), Bill Gatfield (106 pints) and Ken Sievert (64 pints). (Click on image for larger version.)
Hematologists can separate blood into red blood cells, platelets and plasma, which means that donating one pint of your body's 10 pints of blood can help three people in need of blood transfusions. Fermilab is getting ready to host its tri-annual blood drive next Monday and Tuesday, February 21 and 22.

"In the past, we've found that prizes give people an incentive to donate," said Lori Limberg of Fermilab's ES&H, who has been in charge of the blood drives since 2000. "This time, we've gotten prizes including a small crock pot, Angelie's restaurant gift certificate, CDs, T-shirts, Fermilab Art Series tickets and a heavy duty bag."

Fermilab's goal is 100 donors over the two days, for a total of 100 pints. Bill Gatfield of Fermilab's Technical Division has topped that number himself over the years, having given 106 pints. "It doesn't hurt a bit," he said. "Plus, you get free cookies." Added Hans Jostlein of PPD, who has donated 51 pints: "And it's a whole half hour that you don't have to work, all for a good cause."

You can either sign up online or call Lori Limberg at x6651 to reserve a place. Walk-ins are also welcome at the NE Training Room on the ground floor of Wilson Hall, any time between 8:00 a.m. and 2:00 p.m. "We want to let people know that the Web-based registration form is much easier to fill out this year," said Bob Thomas of ES&H, who helps coordinate activities for the blood drive. "It's a smoother, quicker process, and we hope that change encourages more people."

New Neutrino Telescope for South Pole
BERKELEY, CA -- Construction is now underway for a most unusual telescope, one whose light collecting "mirror" will be buried more than a mile beneath the South Pole ice cap. Dubbed IceCube, because its array of detectors covers a cubic kilometer of ice, this telescope is designed not to capture starlight, but to study the high-energy variety of the ghostlike subatomic particles known as neutrinos.

Originating from the Milky Way and beyond, and traveling to Earth virtually unobstructed, high-energy neutrinos serve as windows back through time, and should provide new insight into questions about the nature of dark matter, the origin of cosmic rays, and other cosmic issues.

Universities Help On The ILC
This article is the sixth and last in a series that has focused on the benefits of Fermilab/University collaboration on different accelerator projects.

Universities Help with ILC

Building the proposed International Linear Collider will require innovations surpassing the proportions of every current accelerator. Key areas include superconducting RF cavities and beam focusing, and Northwestern University, the University of Wisconsin and the University of Illinois are among the major university groups working to meet the challenges at Fermilab.

To accelerate the beams, the ILC will require better superconducting RF cavities, which are fabricated with high purity niobium. NU's Materials Science Department, for example, is using a a novel Local Electrode Atom-Probe (LEAP) microscope to study the chemical composition of the niobium. The LEAP decomposes a specimen atom-by-atom, at a rate of 70 million atoms per hour, yielding unprecedented insight into the material for SRF cavities. "Universities have different areas of expertise, and their combined strengths help to confront problems with entirely new possibilities," said David Seidman, Materials Science and Engineering Professor at NU.

The University of Wisconsin is also doing research on applied superconductivity and defect problems in niobium. "This is very exciting for the people involved in the collaboration," said David Larbalestier, Professor at UW who is collaborating with microscopist Peter Lee and theorist Alex Gurevich. "High energy physics has led the way in showing that big teams of people can work together across labs and across countries in a way that advances science at a world level."

Another challenge requires major advances in focusing beams while preserving their properties. "The beams are the size of hemoglobin molecules when they collide. That has never been done before anywhere," said George Gollin of the University of Illinois, who is working on a pulse compression kicker to extract beam from the damping ring, which cools and focuses bunches of electrons. "We're trying to reduce the size of the damping ring from 17 km. circumference - the size of the TESLA design's - to 6 km. circumference. Although the ILC detectors will also need better resolution, we have more confidence in them; the accelerators, on the other hand, are daunting - they're the scary thing."

Announcements
