COUPP scientists fill water tank for bubble chamber

The water tank for the COUPP experiment, which is currently located at DZero for testing, will allow scientists to filter out background noise.

The tank is full, the hot tub pump is running and the water is close to 90 degrees Fahrenheit. Just don't jump in.

Because although scientists with Chicagoland Observatory for Underground Particle Physics, or COUPP, have something to be happy about, it isn't the installation of a hot tub on the bottom floor of DZero.

COUPP scientists finished filling their experiment's water tank on Oct. 30 and installed an array of photomultiplier tubes in mid-November. The tank surrounds the newest and largest prototype quartz bubble chamber, which contains 60 kilograms of a liquid called iodotriflouromethane, or CF3I.

The foam raft will support photomultipler tubes for the COUPP experiment. Scientists installed both in November.

By keeping CF3I on the verge of boiling and shielding it from cosmic interference deep underground, COUPP scientists hope the chamber will be sensitive enough to detect dark matter interacting with the liquid.

The neutron-shielding tank will help COUPP scientists differentiate between ordinary matter, which both the bubble chamber and the water tank will detect, and dark matter, which only the more sensitive bubble chamber will detect. An array of photomultiplier tubes floating on top of the water on a foam raft will record flashes of light from ordinary matter interacting with water in the tank, said Russ Rucinski, project engineer for COUPP.

As the tank is at ground level and highly exposed to cosmic rays, scientists are only testing if the setup can detect ordinary matter. Cameras monitoring the transparent quartz chamber have already detected bubble events produced by rays from cosmic sources.

The filling process began on Oct. 15. After noticing minor rusting, project members drained the tank and replaced a few components with stainless steel. Filling resumed on Oct. 29 and finished about 10 hours later, while a hot tub pump heated water to an initial temperature of 86 degrees Fahrenheit.

Rucinski says tests will probably run through November. Scientists will then test the final quartz chamber, which is made of higher-grade quartz, this winter in the NuMI tunnel.

First neutrino events observed at T2K near detector

From Interactions.org, Nov. 24, 2009

Physicists from the Japanese-led multi-national T2K neutrino collaboration announced today that over the weekend they detected the first events generated by their newly built neutrino beam at the J-PARC accelerator laboratory in Tokai, Japan.

From the Accelerator Physics Center

Не имей 100 рублей, а имей 100 друзей

Don't have 100 rubles, have 100 friends

- Russian proverb

Vladimir Shiltsev

Vladimir Shiltsev, director of the Accelerator Physics Center, wrote today's column.

It is an exciting time to be a scientist at Fermilab. The list of projects and ideas that people are working on is growing every day. As usual, there is never enough money to fully fund all the wonderful science ideas that we have, but I see a good deal of enthusiasm and a "can-do" spirit that moves us ahead in many areas.

Research at Fermilab always has depended on this can-do spirit and the informal collaboration among people from different departments and divisions, and today it is more important than ever. The Accelerator Physics Center depends and thrives on this approach. Whether we are developing new beam collimation techniques, the concept for a high-intensity neutrino source, new high-temperature superconductors and fast-cycling superconducting magnets or electron cloud studies, our work always benefits from the help, knowledge, experience and institutional memory that we find throughout our laboratory.

I also encourage our scientific leaders to go directly to division and department heads and seek support to make things happen. This approach makes their work fun and rewarding. It also helps retain our best and brightest "can-doers."

When I talk to people who have been at Fermilab for a long time, I often hear about the good old times and how the can-do spirit of the early days of the laboratory has been diminished by too many reviews and too much red tape. But that is something that people have always complained about.

Fermilab founding director Bob Wilson sent a handwritten note to colleagues about keeping the Fermilab spirit alive.

More than 30 years ago, our founding director, Robert Wilson, wrote, "Let's try hard to keep the good old can-do informal spirit of Fermilab alive! I ask each of you to be intolerant of creeping bureaucracy!"

Fortunately, we are far from being bogged down in bureaucracy. The regular rotation of our scientific leadership supports our can-do culture and continues to infuse us with new ideas. In Russian and European scientific societies, where I came from, it is a common to be "born as a scientist" and work your entire productive life in the same group, often under the same boss. In contrast, in my 13-year career at Fermilab I've worked for 10 different supervisors, learning new things from every one of them.

We need to remain focused on reaching our research goals rather than waiting to see what the boss will order. With our strong can-do approach and the help of lots of friends, we will continue to achieve our goals and make discoveries.

Funding cuts threaten globalization of Japanese science, scientists fear

From Interactions.org, Nov. 24, 2009

Faced with the prospect of significant reductions in science funding by Japan's central government, leading scientists have expressed concern about the effect on the nation's nascent science globalization effort.

"Just two years ago, with great fanfare, the Japanese government announced its intention to globalize our nation's science," said Professor Hitoshi Murayama, MacAdams Professor of Physics at University of California at Berkeley and the founding director of the Institute for the Physics and Mathematics of the Universe at the University of Tokyo in Kashiwa. "Now it is reversing its policy to significantly reduce or cancel much of its globalization effort in science."
