National Lab Day brings Fermilab physics to students

Fermilab scientist Al Sondgeroth demonstrates force and motion to students from Annunciation BVM School in Aurora.

"I want to try, too!" This was the chorus that rang out across Jennifer Wardynski's sixth grade class last Tuesday, when Fermilab's Al Sondgeroth got students involved in a demonstration of angular momentum at Annunciation BVM elementary school in Aurora.

Sondgeroth was one of 20 Fermilab volunteers who gave hands-on presentations in area elementary and high schools last week to celebrate National Lab Day. His presentation gave students an opportunity to experience Issac Newton's laws in action.

"It helped bridge the gap between the abstract concepts of physics and real-world applications that are all around us," Wardynski said.

In addition to Sondgeroth's presentation on force and motion, volunteers talked about topics such as electricity and magnetism, light and color and the physics of sports.

On Thursday, Fermilab Deputy Director Young-Kee Kim spoke to the young women in teacher Falguni Soni's chemistry classes at Rosary High School. Her visit to Rosary was prompted in part by the interest of sophomore Emily Launer, who wrote a prize-winning research piece on the history of Fermilab.

Kim discussed the field of particle physics and some of the scientific mysteries that Fermilab pursues. She also encouraged the girls who have an interest in science and advised them not to be daunted by a field historically dominated by men.

Many of the students said the presentation helped them relate the science that they are learning about in the classroom to the physics at Fermilab.

"It was all really interesting," said junior Mary LeDoux. "I had heard some of the information about science done at Fermilab before but it really helps to hear it all again because these are very deep concepts."

National Lab Day is a response to President Obama's call to encourage students across the country to learn about math, science, technology and engineering. Over the course of the week, Fermilab presentations reached about 2,500 elementary and high school students.

Letter from Hawaii

Thank you for Pier Oddone's National Lab Day visit

Editor's note: Last week, Fermilab Director Pier Oddone devoted a day of his Hawaiian vacation to a celebration of National Lab Day. Oddone visited Punahou School in Honolulu to share with students the adventure of a life in science. Punahou School, a member of the Quark Net program, is President Obama's alma mater. Following the visit, Punahou School Science Teacher Johannes Adams sent this letter of appreciation.

Fermilab Director Pier Oddone with students at Punahou School in Hawaii for National Lab Day.

Dear Fermilab community,

The Punahou community is very thankful to Pier and Barbara Oddone for talking to students and faculty from Punahou School, Sacred Hearts School, Roosevelt High School and Kahuku High School.

The kids were fascinated by Mr. Oddone's accounts of his life journey, mystified by the mysteries of the universe and had their curiosities piqued by all of the "unanswered" questions in particle physics.

During his visit, Mr. Oddone held an informal talk, gave a lecture, held question and answer sessions, signed autographs and took pictures.

En route to his next destination, Mr. Oddone navigated through gawkers, hangers-on and particle physics fans. The Punahou campus continued to remain abuzz about how nice, genuine, and down-to-earth both Mr. and Mrs. Oddone were.

We are grateful to Carlyn Tani for taking photos during the event, and thankful to the student from ITV who recorded the events.

I would also like to express thanks to Darcy Iams, the physical plant, and security at Punahou for making the visit possible and to Marge Bardeen, Michelle Gleason and Bob Peterson at Fermilab for having the vision, energy and enthusiasm to share their passion for physics.

IB1 Test Facility prepares for things to come

Ruben Carcagno, head of the Test and Instrumentation Department in the Technical Division, wrote this week's column.

Ruben Carcagno

Magnets and radio-frequency cavities are at the heart of particle accelerators, generating the magnetic and electric fields that bend, shape and accelerate a beam of particles. The cost and scientific potential of particle accelerators, such as the proposed Project X, strongly depends on the performance of these critical components.

Superconductivity now is the key technology to produce the best magnets and RF cavities. Advancing this technology requires adequate facilities with the infrastructure to test superconducting magnets and RF cavities under standard and extreme operating conditions. Those facilities also provide the testing that is necessary to ensure the quality of magnets and RF cavities before they are installed in an accelerator.

At Fermilab, the Industrial Building 1 Test Facility provides this infrastructure. The IB1 Test Facility, which is part of the Technical Division complex's industrial buildings, has a very successful history. For more than 30 years, it supported conventional and superconducting magnet testing for projects such as the Main Ring accelerator, Tevatron, Superconducting Super Collider dipoles, Recycler and LHC interaction region quadrupoles. In the last few years, we have used the facility to test magnets for the LHC Accelerator Research Program and Fermilab's High-Field Magnet Program as well as corrector magnets for the Booster accelerator and solenoids for a High-Intensity Neutrino Source.

In July 2007, we expanded the scope of the IB1 Test Facility by starting up its first SRF cavity vertical test stand. To date we have conducted approximately 90 SRF cavity tests. With funding from the American Recovery and Reinvestment Act, we are adding two more test stands to this Vertical Cavity Test Facility as we anticipate that in the future we'll need to test up to 250 cavities per year. We developed the design for these new test-stand cryostats together with our collaborators at institutions in India. Using ARRA funding, we also are upgrading the IB1 cryogenic system to match the increased cooling and reliability demands of our magnet and cavity test areas.

This is a very busy and exciting time for the IB1 Test Facility as we prepare its infrastructure to once again meet the challenge of providing support for the testing of critical components for a proposed accelerator on the Fermilab site.

Search for dark matter still empty-handed, scientists say

From Space.com, May 10, 2010

The search for elusive dark matter is still drawing a blank, according to new results from one of the most powerful experiments currently hunting for the invisible stuff.

The XENON100 experiment buried deep underground in Italy is one of a handful of efforts to directly detect dark matter, a substance thought to be plentiful in the universe, despite the fact that our telescopes can't see it. Astronomers can detect dark matter's gravitational effects on normal matter, but have not yet confirmed a direct measurement of the sought-after substance.

While a few teams have reported potential sightings of the strange stuff, the new results from XENON100 - which its scientists say is the most sensitive search to date - suggests those possible signals were not dark matter. If they were, XENON100 should have detected dozens of events unless the properties of dark matter are very different than expected.
