Fermilab offers Family Open House, Sunday, Feb. 13, 2005
Visitors need to register by February 10 to receive free tickets
Cryo Show
A liquid-nitrogen show will be one of the featured events at the Family Open House on February 13. (Click on image for larger version.)
From historical scientists to hands-on activities, from an accelerator tour to a liquid-nitrogen show, the Family Open House on Sunday, February 13 at Fermilab offers something for the entire family.

Organized by the Fermilab Education Office, the Family Open House celebrates the World Year of Physics 2005, which marks the anniversary of three revolutionary publications by Albert Einstein one hundred years ago. Visitors can join tours of two small accelerators on the Fermilab site, and they can visit the viewing area on the 15th floor of Wilson Hall, where Fermilab physicists will be available to talk and answer questions. A new exhibit, "The Quantum Universe," is open as well. As a special surprise, visitors can "meet" four famous scientists of the past 100 years and learn more about their accomplishments.

Osteoporosis Starts Early - Prevention Should, Too
Even though King Tut's recently-examined bones have survived for over 3,300 years, it took amazing foresight of mummy preservation and protection. We could all take some tips on caring for our bones from King Tut — even if it's just for while we're alive.

"Many people don't realize that the decrease in bone mass that causes osteoporosis starts early — even as young as 30," says Bernie Dugan

of Fermilab's Lab Services, who is organizing an osteoporosis lecture and screening at Fermilab. "There are many things in life that you can't control, but you can control this. We all want to remain active as we age, but we need to give thought about staying healthy while we're still young."

The presentation, called "Building Better Bones," will take place on Tuesday, February 15 from noon until 1:00 p.m. in the Curia II Conference Room. Jody Springsteen, a nurse with the Kane County Health Department, will talk about the how to determine your risk factors and methods of prevention. After the lecture, Fermilab employees can receive a free bone density screening, although space is limited.

"The screening gives a baseline of information which a woman and her doctor can use to assess future changes," says Dugan. The screening is like an ultrasound: it's quick, painless and non-invasive. Reservations are required for the free screening, and the deadline to register is Thursday, February 10. To make a reservation, contact Dugan at 3591 or by e-mail.

Accelerator Update
January 31 - February 2
- During this 48 hour period Operations established two stores that provided approximately 32 hours and 49 minutes of luminosity to the experiments.
- A ComEd power glitch tripped off the TEL and ARF1, but store and stack survived

For Some Girls, the Problem With Math Is That They're Good at It
By Cornelia Dean
A few years ago, I told Donald Kennedy, editor of the journal Science, that I wanted to write an essay for his publication. It would say, "Anyone who thinks that sexism is no longer a problem in science has never been the first woman science editor of The New York Times."

I never wrote the essay. But the continuing furor over Dr. Lawrence H. Summers's remarks on women and science reminds me why I thought of it.

Following Up on the Mysteries of Run I
The distribution of missing transverse energy expected from the Standard Model compared with that observed in the CDF Run II top dilepton sample. (Click on image for larger version.)
Searching for new physics often involves looking for excesses of events over Standard Model expectations, but CDF recently submitted a paper describing a search using a different, complementary technique.

The analysis has its history in the sample of top quark pair decays containing two leptons collected in Run I of the Tevatron. CDF and DZero observed not only a slight excess of events in this sample, but also some peculiar kinematic properties in some of the events — such as anomalously large missing energy. These peculiarities led some to speculate whether there was "something else" lurking in the top dilepton sample.

Awaiting the Run II data, a team of CDF researchers chose four kinematic variables to study (one of which is shown in the accompanying figure) and developed a statistical technique to isolate subsets of events in which these variables seemed most inconsistent with the Standard Model. If the effect observed in Run I was something more than just a stastical fluctuation, this method would be ready to catch its reappearance in Run II.

Unfortunately, when CDF "opened the box" on the larger Run II data sample, no particular subset stood out pointing the way to new physics. The sample was not without its own set of peculiarities, but a quantitative assessment showed that it was nothing that couldn't be explained by the Standard Model and statistics. The Standard Model has passed another test — but that's not always the answer we want to hear!

(Left to Right) Originally from Rochester, Andy Hocker (FNAL), Paul Tipton (Rochester), and Andrew Ivanov (UC Davis) performed this measurement. (Click on image for larger version.)

- Ronald L. Norton, who worked at Fermilab
Ron Norton
Ron Norton
from 1970 until he retired in October of 1996, died on January 31 at his home with his family at his bedside. He was 66. Norton worked for the Cryogenics Systems group in the Accelerator Divison. While at Fermilab, Norton was the Task Manager for the installation of the Tevatron Transferline, High and low Pressure Helium headers, and N2 return header. He supervised the installation of the Cryogenic piping and initial testing of the DZero detector central calorimeter. He also supervised the modification of cryogenic transferline and piping headers for the CDF and DZero detector installation. Norton was also the Task Manager for the installation and construction of the Tevatron satellite refrigerators and compressor buildings.
