Fermilab's Safety Incentive Program Achieves New Records|
A little more than a year ago, ES&H introduced a safety incentive program for
employees. Fermilab's Laboratory Safety Committee developed a Web page that
keeps track of the number of days since the last DART (injuries involving Days Away
from Work, Restricted work or Transferred) case. Once all Divisions and Sections
reach seventy-five days or more without a DART case, a computer randomly selects
three employees per day who have their names listed on the LSC homepage and receive
a Fermilab polo shirt.

One year later the safety incentive program is without a doubt a success.
As of yesterday, 111 employees have received polo shirts from the LSC, and
Fermilab has had 111 consecutive days without a DART case. This surpasses the
former record of 108 days without a DART case. "People are clearly paying a great
deal of attention to safety and the planning of their work," said ES&H head Bill
Griffing. "Even though the record is great, the most gratifying thing is to see
the decrease in the number of injuries at the lab." If you are one of the 111 employees
who have been notified about winning a polo shirt but have not yet picked up your shirt,
please contact Bill Griffing (x8069) or Liz May (x8277) to arrange a time to pick it up.
TeV4LHC Workshop Starts Tomorrow|
TEV LHC Poster (Click on image for larger version.)|
The first in a series of TeV4LHC workshops will start at Fermilab
tomorrow and will run through Saturday. Physicists from Fermilab and institutions around the U.S.
and Europe will meet to discuss how data and experiences from the Tevatron can
be used in preparing for the LHC experimental program.
The workshop will include overviews of the physics challenges at the Tevatron
and those expected at the LHC, and several working groups will hold parallel
sessions to discuss the overlap of physics at the LHC and the Tevatron and to
make plans for more detailed studies.
All Fermilab employees and users are invited to the workshop. |

How Things Work: Particle Accelerators
by Peter Battaglino
Physics is pretty complicated stuff. So complicated, in fact, that physicists often
have to resort to violent tactics in order to probe the subatomic universe: they
smash atoms. Doing physics with an atom smasher is a little bit like dropping a
monitor off the eighth floor stairwell of Wean Hall and trying to figure out how
it works from the little pieces of glass, wire and circuit-board left over. But
the atoms go a lot faster, there are a lot more pieces at the end, and above all,
it costs a lot more tax money.
Atom smashers, more accurately known as particle accelerators, boost charged
particles like electrons and positrons or heavy ions and their anti-particles to
almost the speed of light and then heave them into one another. If they collide,
an explosion of so-called “daughter” particles is produced, many of which decay
into further daughters, and so on. This explosion occurs inside a strong magnetic
field, which causes all of the charged particles produced to bend in circular arcs,
the curvature of which can be used to deduce which particle is what. This typically
happens on the order of a billion times each second.
Shutdown Work on Schedule|

The Fermilab accelerator complex is in the fourth week of a scheduled shutdown.
Since August 23, hundreds of employees have worked on installing new equipment,
making repairs and carrying out regular maintenance tasks. From the Computing Division
to the Particle Physics Division, employees from around the lab are helping the
Accelerator Division to meet the tight schedule.
According to Roger Dixon, head of the Accelerator Division, the installation of
electron cooling and the work on the NuMI beam line are the two most important
shutdown projects, representing the critical paths to complete the shutdown.
The Ecool project requires the installation of cooling tanks in the Recycler beam
line in the Main Injector tunnel. "The planning for the installation of Ecool is
going really well," said Bob Mau, who coordinates all shutdown work. "The Ecool
group reduced its schedule from 15 to 13 weeks, and they are right on schedule."
When operational later in 2005, Ecool will reduce the size of the antiproton beam
inside the Recycler, leading to higher Tevatron luminosity.
The NuMI beam line will extract protons from the Main Injector and transport them
to the NuMI target hall, producing neutrinos for the MINOS experiment. "The major
magnets of the new beam line were installed during the 2003 shutdown," said NuMI
physicist Rob Plunkett. "Now we are working on the hookups." In the last few weeks
technicians have installed custom-designed shielding to protect the Recycler beam
line, which runs past the NuMI beam extraction point.
Additional work is going on in all accelerators, from the installation of a new
prototype cavity in the Booster to improving the stacking rate of the Antiproton
Source by installing motorized stands for magnets. Fermilab Today will highlight
the most important projects in more detail in the next couple of months.
NUMI Tours for Employees and Users Full|
The Education Office received an overwhelming response from employees and users
who would like to take a tour of the NUMI tunnel and the MINOS near detector hall.
All of the currently scheduled tours are now full. To request additional tours,
please send an email to Nancy Lanning.
