Fermilab Recognized for Participating in the Toys for Tots Program|
Last fall, Charisse Malo, of the Accelerator Division, conducted
Fermilab's first toy drive for the U.S. Marine Corps Reserve Toys
for Tots Program. Fermilab recently received a certificate of
appreciation for donating 193 toys to the program.
All of the toys that Malo collected were distributed in DuPage County.
The Toys for Tots Program collected approximately 31,000 toys in
DuPage County this year. "We spent quite a few weekends sorting and
counting the toys," said Malo, who recruited her two children to help.
According to Malo, hot items this year included easy bake ovens,
binoculars and stuffed animals. "It was a great experience," she said.
"We'll do this every year." Malo plans to start collecting toys for
the 2004 toy drive around Thanksgiving. If you are interested in
volunteering, contact Charisse Malo.

Required Reading: Science Committee Chairman Boehlert on Science Funding
House Science Committee Chairman Sherwood Boehlert (R-NY) was the keynote speaker today at a workshop for the future National Synchrotron Light Source at Brookhaven National Laboratory. Boehlert's remarks at this workshop, as they are at hearings, were to the point, and concerned a constant problem in Washington: money. This year that problem is greater than it has been in a long time, so Boehlert's words are particularly important. Selections follow:
"But one doesn't need a degree in physics to understand the value of a scientific tool that furthers human understanding of matter while answering practical questions in materials science and biology; a tool that is of use to both academic and industrial researchers; a tool that attracts the best researchers from throughout the world. The U.S. simply must invest to upgrade its capabilities in this area, building on the expertise that Brookhaven and the researchers who use its facilities have developed over the last few decades.
A Glance at Glancing Collisions |
|The rate of elastic collisions as
a function of angle (|t|, momentum transfer, is proportional to
the square of the scattering angle). The DZero points are normalized
to the E710 points and cover a new angular region. A theoretical prediction
from Block et. al. describes the data well. (Click on image for larger version.)|
In about 25% of their collisions protons and anti-protons exchange only
glancing blows (elastic scattering). These are difficult to measure
because the resulting particles proceed at very small angles down the
beam pipe. For Run II DZero has installed the Forward Proton Detector
(FPD) to measure events in which either the proton, anti-proton, or both,
remain intact (which is typical of these glancing collisions).
|Jorge Barreto of LAFEX|
Brazil worked on this
The FPD was built under the leadership of Andrew Brandt,
of University of Texas, Arlington, and Alberto Santoro,
UERJ/Brazil, in a U.S./Brazil collaborative
international project. The detector consists of "Roman Pots,"
which are remotely controlled and can be moved close to the beam
(within a few milimeters) during stable beam conditions and retracted
These pots contain particle detectors that record the passage
of the protons and antiprotons and provide information for
reconstruction of these glancing collisions.
|Jorge Molina of LAFEX|
Brazil worked on this
DZero has now made its first measurement using these new detectors.
It has measured the rate of glancing collisions as a function
of the angle of the collision in a region of angle never before
measured at Tevatron energies, giving insight into the size
and structure of the proton. As shown in the figure,
our first data is well described by theory (the blue curve).
This first diffractive physics result from DZero will be shown
at major conferences this spring and we anticipate many more
interesting results in the future, using this new capability of
the DZero experiment.
