Joint Antiproton Accumulator-Recycler Store Achieved|
On June 9, the Accelerator Division completed the first "mixed-pbar shot,"
in which antiprotons from both the Accumulator and the Recycler were
transferred to the Tevatron for the same store. Store 3564, which collided
from noon Wednesday until Thursday evening, included eight bunches of
antiprotons from the Recycler and 28 bunches from the Accumulator.

"Some careful choreography and planning was required to make this happen,"
said Elvin Harms, head of the Antiproton Source Department. "It took many
people in the Accelerator Division to make this work, but special credit
goes to Dave McGinnis and Run Coordinator Jim Morgan for championing this
mode of operation."
One month of planning by Harms, Dave Capista, Cons Gattuso, Jerry Annala,
Brian Hendricks, Stan Johnson and Jean Slaughter preceded Wednesday's event.
The Recycler regularly takes antiprotons from the Accumulator for commissioning
purposes and has been used to provide antiprotons for two stores since
January 2004, but this marks the first time that the two machines were
combined for one store. More mixed-pbar shots are planned in order to
integrate the Recycler into normal accelerator operations and possibly
increase Tevatron luminosity.
Last week's article, "Forty Students from Wylie, Texas Visit Fermilab," contained
a typo. Leon Lederman's quote should have said, "A good teacher should be filled with the
sense of science and not be blasé about things." Fermilab Today regrets the error.

- During this 48 hour period Operations established two stores that
provided approximately 35 hours and 31 minutes of luminosity to the experiments.
- Accelerator experts establish the first Mixed-Antiproton store on
- Booster suffers from a failed PFN kicker cable
- CDF data taking diminished due to colliding beam problems
- Pbar stack lost

Newly devised test may confirm strings as fundamental constituent of matter, energy
Santa Barbara, Calif.--According to string theory, all the different particles that constitute physical reality are made of the same thing--tiny looped strings whose different vibrations give rise to the different fundamental particles that make up everything we know. Whether this theory correctly portrays fundamental reality is one of the biggest questions facing physicists.
In the June on-line Journal of High Energy Physics (JHEP), three theoretical physicists propose the most viable test to date for determining whether string theory is on the right track. The effect that they describe and that could be discovered by LIGO (Laser Interferometer Gravitational-Wave Observatory), a facility for detecting gravitational waves that is just becoming operational, could provide support for string theory within two years.
The Shocking Truth
In a typical year, 80 people die and 800 people are injured
by lightning strikes in the United States.
Many of us have actually seen lightning strike on Fermilab's site,
and lightning damage is not unusual here.
The cloud-to-ground lightning strike
rate is approximately five per km2 per year in the Midwest.
Based upon that calculation, we expect that Fermilab is struck by lightening
at least 100 times per year.
The most dangerous place to be during a lightning storm is outdoors.
The National Weather Service recommends use of the 30/30 rule to avoid
injury. When lightning is seen, count the time until thunder is heard.
If it is 30 seconds or less, seek shelter immediately. Stay there
for at least 30 minutes after the last rumble. The shelter should be
a substantial building such as a home or inside a car with a metal roof.
Covered picnic shelters, tents, and convertibles even with the roof up are
Keep in mind that high points attract lightning and conductors transmit
electrical surges. Avoid high locations as well as tall objects such as
isolated trees. Metal fences, power lines, water, and less obvious
conductors (e.g., rebar) effectively increase your size as a target.
If you feel your skin tingle, or your hair stand on end, you are about
to be struck by lightning! Squat low to the ground on the balls of your
feet. Place your hands on your knees with your head between them.
Make yourself the smallest target possible, and minimize your contact
with the ground.
Have a great day and let's work safely all week!
