There's more than one kind of barn at Fermilab.
The time: 1942, in the ominous early days of World War II. The place: Purdue
Memorial Union, Lafayette, Indiana. The people: Manhattan Project physicists
Marshall Halloway and Charles Baker. The event: a dinner conversation that
would change the future of physics. Over dinner, Halloway and Baker tried to
devise a good term for the target area that a nuclear particle represents in
a collision. They dismissed "Oppenheimer" and "Bethe" as candidates, and
then considered John Manley, director of the Purdue group at Los Alamos,
where the atomic bomb was being built. But the double-syllabic "Manley" was
cumbersome; and the first name, "John," could be confused with other
The physicists considered that the area of 10-24 cm2 -- a typical nuclear
cross-section -- was quite big in the realm of particle physics. In fact, it
was relatively "as big as a barn." The name was snappy, and it stuck -- but
only inside the collaboration, and not in public. Because of the need for
communicating Manhattan Project information as secretly as possible by
telephone, the term "barn" was immediately classified, and wasn't officially
de-classified by the government until 1948.
Now particle physics laboratories like Fermilab use "barns" to describe the
success of their colliders. Reports of reaching "one inverse femtobarn,"
indicating a great number of collisions over a tiny area, made big news at
Fermilab in 2005. Though the definition of the term is complex, even
non-physicists can have a conceptual understanding of the connection between
barns, collisions and success at the Tevatron.
Learn more about barns--and how they are used by particle physicists now.
To the Editor:
Thank you for your article on the Dark Energy Survey in yesterday's issue
of Fermilab Today. However, I must clarify one significant point. Readers may
have received the impression that the Department of Energy and the National
Science Foundation have approved the Dark Energy Survey. In fact, DES has
just begun the process that DOE and NSF will use to decide whether to
approve the project and request funding for the construction of a Dark
Energy Camera. Unless and until the project receives agency approval and
is funded by Congress, we remain in the R&D phase. Although we are working on prototypes, the camera
construction itself must await approval.

From Science Daily,
January 23, 2007:
Synchrotron for neutral molecules built
BERLIN, Jan. 23 (UPI) -- German scientists reported the construction and successful operation of the world's first synchrotron for neutral molecules.
Gerard Meijer and colleagues at the Fritz-Haber Institute, part of the Max Planck Society in Berlin, said the device could open a new avenue for the study of collisions between molecules, promising unique insights into their physical properties and chemical reactions.
Synchrotrons are devices in which particles move in synchronized bunches in a circular path. They are widely used in high-energy particle physics, such as at Fermilab in the United States.
But the new German device, with a circumference of 32 inches, is said to be the first synchrotron to work with electrically neutral particles.
This column is written by ES&H Director Bill Griffing (left).
A few weeks ago I had the opportunity to travel to CERN. It's impossible not to be impressed with the sheer magnitude of the operation, the size of the detector halls, and the scale of the detectors taking shape within them. Daily meetings are essential to coordinate the myriad work activities going on simultaneously as the LHC approaches start-up. There is still much work to be done to get the CMS detector assembled and to finish the infrastructure around it. But those responsible for the work understand that the schedule is secondary to job safety.
In comparing worker safety between Europe and the U.S., I found that I had some misconceptions. I did not expect to see the strong commitment to safety that was evident from my tours and from our interactions with the workers we encountered along the way. And I was very impressed with the leadership of the CERN Safety Commission as well. I learned that many objective observers consider Europe to be far ahead of the United States when it comes to worker safety. From my own observations, I can say that I did see some practices that tended to support that assertion, but I don't think the differences are dramatic.
I also learned that Europeans don't necessarily have a completely factual view of worker safety in the U.S., either. In discussions, I repeatedly heard that worker safety in Europe was rooted in "common sense," implying directly or indirectly that in the U.S. it is not. When I finally tired of hearing this, I pressed my guide to explain why he felt that we in the U.S. don't apply a common-sense approach to safety. He told me that he and his colleagues believed that in the U.S., we are so prescriptive as to safety precautions that people are not allowed to apply common sense in matters of safety. "After all," he said, "you are the nation that requires coffee to be labeled with 'hot' warnings." I suppose we have our legal system to thank for that perception.
During my visit, I was invited to give a presentation on our approach to
worker safety to the CERN Safety Commission leadership. I also heard a
presentation about the changes underway in CERN's approach to its their
worker safety program. I believe the exchange benefited both partners, and
was an important step in opening a dialogue between CERN and Fermilab that
will lead to improvements in both our safety programs.
Sharon Austin to retire
Sharon Austin, a Fermilab employee since 1981, will retire January 31, 2007.
Austin has contributed to a number of projects at the lab,
including Tevatron spool production, SiDet, e-cool and high-field magnet R&D.
Prior to these assignments, she was part of Detector Support in the Physics Section
and Detector R&D in the Particle Detector Group.
An informal retirement party is scheduled for January 31 at 3:00 p.m. in Lab 6; feel free to stop by to say goodbye.
Fermilab's Ask-a-Scientist program is looking for volunteers to discuss physics with the public once or twice a year. The program takes place on the 15th floor of Wilson Hall on select Sunday afternoons. Contact Peter Garbincius (firstname.lastname@example.org) for more details; read more about the program here.
Brown Bag Seminar on Internet Safety
Wellness Works presents a Brown Bag Seminar on Internet Safety, "Avoiding
Internet Predators and Scams," offered by Justin Fitzsimmons, Assistant
States Attorney for Kane County. The seminar will be held today, January 24,
from Noon to 1 p.m. in Curia II.
