Beams Division Renamed
|
Roger Dixon |
In response to a request by Roger Dixon, Head of the Beams Division, Director
Mike Witherell has changed the name of the Beams Division to the Accelerator
Division. "I agree that the new name conveys the nature of the organization
more effectively, especially to the outside world," said Witherell. The new name
is already in effect.

News from the Users Executive Committee
|
Sharon Hagopion, UEC Chair |
The Fermilab Users Executive Committee met on November 22.
Director Mike Witherell talked to the UEC about the status of the laboratory.
The UEC learned that approximately 250
people worked in the
tunnels during the shutdown. The biggest success so far was the reduction in
the emittance in the recycler. Witherell also mentioned recent reviews of
the accelerator,
BTeV and NuMI/MINOS and discussed the DOE 20 year Science Facilities
Plan.
A number of other people also presented at the UEC meeting.
Leslie Groer, of DZero and a UEC member,
reported on a meeting at BNL on
Visa Issues. Elliot McCrory, of the Beams Division, presented a phenomenological model
of Tevatron Operations. Jean Slaughter, of the Beams Division,
talked to us about how
experimenters can help improve accelerator performance.
Judy Jackson, of Public Affairs, talked about
Fermilab publications and Interactions.org, a new international web site for HEP communications.
The full minutes of the meeting are available online.

LC Steering Committee Issues Charge to
Technology Recommendation Panel
The International Linear Collider Steering Committee has published the
charge to
the International Technology Recommendation Panel appointed by the
International Committee for Future Accelerators. The
Panel, whose 12 members were announced
on November 20, is charged with recommending which of two leading
accelerating technologies will
form the best choice for a future international linear collider. A
technology decision is required in order to commence an international
design for the future accelerator.

From Physics News Update, December 3, 2003
The Top Physics Stories of 2003
The first three on our list concern the sharpening of our understanding of
the big bang era, evidence for new quark groupings, and progress in
manipulating quantum gases. At the largest size scale, new observations
from the Wilkinson Microwave Anisotropy Probe (WMAP), the Sloan Digital
Survey and other telescopes have reduced the uncertainties in the values
of such cosmic parameters as the Hubble constant, the age of the universe,
and the fractions of total energy vested in the form of dark and luminous
matter (PNU #624; 659).

Good Morning!
|
Mike Witherell
|
The startup of Tevatron operations, which got off to a very good start,
suffered its first major unscheduled shutdown last week. As you can
read in the Accelerator Update, a large quench damaged a cryogenic
element in the Tevatron that will require a warm-up of the sector
to repair, an operation that will take a week to ten days.
What happens after such an event? A large number of people from around
the Accelerator Division (formerly known as the Beams Division)
devise a plan to accomplish the repair quickly and carefully and
to make best use of the unscheduled shutdown. Accelerator experts
conduct an investigation into the series of events to understand
how to prevent this particular incident but also to see whether one
can abort the beam in a more controlled way when something like this
occurs. All of the AD departments and the running experiments turn in
work lists for maintenance and repair jobs that require beam to be off.
The operations department decides which work to do this week to take best
advantage of the unscheduled shutdown. Later in the week, accelerator studies
will be done in the unaffected tunnels, getting work done that would
otherwise require a pause in accelerator operations later.
Meanwhile, progress continues in other parts of the accelerator complex.
Experts tuning the Booster were able to improve the proton intensities for
collider operation and for MiniBoone to the levels achieved before the major
changes made during the annual shutdown. Tuning of the Antiproton Source
restored a good rate for collecting antiprotons. Some of those antiprotons
were successfully transferred to the Recycler and stored there with excellent
lifetime, confirming the good news about the results of the massive amount
of work done on the Recycler during the ten-week shutdown.
We are losing a week of operations this week, something that happens a
few times per year. The accelerator experts will be improving performance
in the weeks to come as they convert their improved understanding of the
accelerators into higher luminosity and steadier operation.
