What's up with the Linear Collider?|

Linear Collider R&D at Fermilab|
Fermilab scientists and engineers are active collaborators in the development of both X-band (warm) and superconducting (cold) technologies under consideration for an International Linear Collider.
"Warm" radiofrequency cavities operate at 11.4 GHz, within a range designated as "X-band" in rf nomenclature dating back to research secrecy policies during World War II. Cold rf cavities operate at 1.3 GHz, within the "L-band." Much of the development of warm technology has centered at SLAC and at KEK Laboratory in Japan, while the TESLA collaboration centered at DESY, in Hamburg, Germany, has led the efforts in cold technology.
"Fermilab has made important contributions to both warm and cold technologies," said Shekhar Mishra, coordinator of Fermilab's linear collider efforts. "We will continue to expand our work in accelerator physics and technology to be a significant player in ILC design and construction."
In collaboration with SLAC and KEK, Fermilab has developed accelerating structures and girders for the warm ILC. And, for more than a decade, Fermilab scientists have been collaborators on the TESLA project, where key components of the TESLA Test Facility, including modulators and radiofrequency couplers, are provided by Fermilab.
In collaboration with other laboratories, universities and industry Fermilab is progressing in these areas:
"When the International Technical Recommendation Panel makes its decision," Mishra said, "Fermilab will be prepared to contribute in either direction."
- Development of the electron source for a cold linac
- Design of a new TESLA damping ring; and study of a warm pre-damping ring. Damping rings "cool" the motion of electrons and positrons so the beams can be tightly focused. Fermilab could continue developing the final design of a damping ring for either warm or cold technology
- Development of simulation tools to study beam transport from damping ring to interaction point
- Development and production of warm rf structures that have achieved performance requirements for use in a linear collider
- Design, production and testing of a cold niobium accelerating cavity and its power input devices

The photoinjector is a sister to the one at DESY and includes a TESLA cavity that has operated more than five years. Edwards’ group hopes to install a second TESLA cavity in the coming year, to operate at a higher gradient than the present one. (Click on image for larger version.)|

Editor's note: This story is part of an occasional series about
the people and projects of the Fermi National Accelerator Laboratory in Batavia.
By Tom Schlueter
BATAVIA — A noisy elevator ride is required to reach the construction site 350 feet below the prairie grasses at Fermi National Accelerator Laboratory.
The ride lasts 1 minute, 50 seconds before it comes to a halt in a cavern gouged out of limestone.

Computer aids physics research
Large storage space is needed for research in high-energy physics
By Kyle A. Vernon
In a well-hidden corner of campus lies a technological beast.
It is known as the Distributed and Parallel Computing Cluster.
One hundred and ninety-three Pentium Xeon processors, 189 gigabytes
of memory and 73 terabytes of disk storage are all tied together by
the experience and expertise of a joint research team formed by the
university’s physics and computer science departments.
IIT Hosts Successful BEACH 2004 Conference|

The Illinois Institute of Technology hosted the Sixth International Conference
on Hyperons, Charm and Beauty Hadrons ("BEACH 2004") from June 27 to July 3.
The 83 talks at the conference included presentations by Fermilab
experiments KTeV, SELEX, CDF, DZero, MIPP, MINERvA, HyperCP, FOCUS and E835.
"There were a lot of interesting topics covered," said conference chairman
and IIT professor Nickolas Solomey. "KTeV presented a new value for
Vus -- a major constant in particle physics that describes how certain
particles interact with others." This new value, which confirmed a
1999 result from the KTeV hyperon group, affects experiments involving
hyperons and kaons as well as worldwide neutrino physics results.
"This shows how results from one part of our field now impact most
other parts," noted Solomey.
The Vus result was mentioned by the introductory speaker, Nicola Cabbibo,
and the summary speaker, Fermilab's Joel Butler. Cabibbo, a theorist and
professor at the University of Rome and president of the Pontifical
Academy of Sciences, contributed essential pieces to the Standard Model
and to matrix elements such as Vus.
Another major result presented at the conference, and heatedly discussed
in a Wednesday afternoon working group, was evidence for pentaquark states.
While a dozen experiments have reported evidence for the phenomenon,
another dozen haven't seen the states. Bottom quark, charm particle,
and several other new results were also presented.
The main site domestic water flushing was successfully completed this week.
Industrial Cooling Water flushing will take place all next week at Fermilab.
The work will begin Monday, July 19, 2004 at 6:00 a.m. and continue
through 6:00 p.m.,Monday through Friday. You may experience a slight water
discoloration. If you have questions or concerns about this maintenance
procedure please contact Greg Gilbert at x 6835,
