A Strong Fermilab Future
Robin Staffin speaking to the Fermilab Community yesterday. (Click

Robin Staffin, the Department of Energy's Associate Director for High Energy
Physics in the Office of Science, assured a lab-wide audience Thursday that
Fermilab "will play a central and critical role for U.S. particle physics,
both here and abroad."
"We know that budgets have been very stressful, in carrying out our existing
programs with the universities, and in planning for our future," Staffin told an
assembly in 800-seat Ramsey Auditorium, as well as lab employees and users (with
an estimated 250 off-site viewers) watching on
streaming video. "But we're in
this together, as partners," he continued. "I need your help in making a
successful U.S. program and a successful Fermilab for our future. The two
are inextricably linked...Yours is a great laboratory. That's always been the
case in the past, and there's no reason not to see that as the case for the
Staffin's talk addressed concerns over the reductions in the FY'06 budget
request submitted by DOE to Congress in February, compared to FY'05 budget
levels. He described Fermilab's growth within the funding agency as representative
of its importance. "The laboratory is approximately 40% of the national DOE high
energy physics budget," Staffin said. "This is up almost five percent from the
Staffin outlined three overarching goals for the field of high energy physics:
1) realize the full potential of the ongoing research programs including the
Tevatron collider, the SLAC B-Factory, neutrino experiments, and contributions
to the Large Hadron Collider at Europe's CERN particle physics laboratory; 2)
develop a strong coherent experimental program in dark matter, dark energy and
neutrinos; and 3) use future LHC results to build a consensus for launching
the proposed Linear Collider. "The Linear Collider is the highest priority
for a future major facility in high energy physics," Staffin said, but he
added: "We will run the Tevatron as long as it makes sense to do so,

Press Release: Fermilab Colloquium Series Offers
Free Public Talks on World Energy
Situation Beginning Wednesday, April 13|
As rising gasoline prices emphasize the U.S. dependence on
oil, the Department of Energy's Fermilab will
explore the present and future state of the world's energy situation, with
three free public talks over the next few months. These energy-themed
presentations on April 13, June 1 and July 6 are aimed at
and are free and open to the public. Part of the longstanding Fermilab
Colloquium series, the talks will be offered on Wednesday afternoons at 4
p.m. in the One West conference room on the first floor of Wilson Hall.
Opening the energy series on Wednesday, April 13, Dr. Steve Koonin, Chief
Scientist at BP International and former Provost of the California Institute
of Technology, will present "A Physicist's View of the World's Energy
Situation." Koonin will examine the challenge of ensuring adequate energy
supplies in an environmentally acceptable manner. He will focus on
technical, economic, and social considerations, suggesting possible
solutions and likely energy futures.

Universe spawned stars at a young age
by Andreas von Bubnoff
Spitzer telescope reveals surprisingly robust early galaxies.
The Universe's first stars were born a mere 700 million years after the Big Bang, far earlier than researchers previously thought. The discovery comes from images of stars in galaxies that are so far away their light has taken some 13 billion years to reach us.
What's Up with the ILC?|
The entire International Linear Collider series is available online.
Weerts updates Fermilab ILC community
Last Wednesday, physicist Harry Weerts reviewed the latest International
Linear Collider developments. Giving a
at the weekly Fermilab ILC meeting, Weerts summarized the presentations given
two weeks ago at a Linear Collider Workshop at SLAC.
Weerts shared with Fermilab physicists the main points given in a talk by
Barry Barish, the newly-appointed director of the ILC Global Design Effort.
"Barry said the ILC must be an international effort and have no national biases.
He wants to have realistic sample sites [for hosting the ILC]."
An important step at the SLAC workshop was the institution of a Detector R&D Panel,
and Weerts added that "the accelerator design needs inputs from the physics and
detector studies. The detector outline document is to be ready at the end of
2005 or early 2006. The next important step is the workshop in Snowmass in
A crucial point in developing the ILC design is the discussion about the merits
of two interaction points versus one. Two interaction points, one with a beam
crossing angle of at most 2 mrad and one with at most 20 mrad, would allow
for photon-photon collision experiments in addition to electron-positron
collider operation. A committee is working on a document containing arguments
in favor of or against two interaction points. Weerts emphasized that
"experimenters should contribute to the accelerator design effort, not
just the detectors."
A lot of activity has focused on the development of the electromagnetic and
hadronic calorimeters for the ILC detector(s). The goal is to obtain substantially
better resolution than the LHC detectors. "We are pushing the technology, looking
at calorimeter energy resolution better than ever achieved before. We do
everything possible to get there," said Weerts, who works on ILC detector
One parallel session at the SLAC workshop was devoted to ILC communication issues.
Karsten Buesser, DESY, presented a proposal endorsed by Barry Barish and
communicators at the main particle physics laboratories to start a weekly
ILC newsletter. The majority of the content of the newsletter would be produced
by three dedicated ILC communicators, one each in Asia, Europe and North America.
"It's got to be a global effort with all three regions collaborating," said
Judy Jackson, director of Public Affairs at Fermilab. DOE's Office of Science
has already indicated that it would offer additional financial support for
