From cheese festivals to hayrides, Votava has it down
Computing Division's Margaret Votava created an online calendar for Warrenville residents.
Want to learn how to catch, gut and cook a catfish? Or maybe you'd rather attend a play where actors wander around and the audience follows? Whatever quirky class or event you'd like to do in or near Warrenville, you can find it quickly on a new website created by Margaret Votava of the Computing Division. "There is some really cool stuff happening," she said. "And there is really quirky stuff, too."

Votava started the online, interactive calendar as a hobby. "Part of the inspiration was looking for cool things to expose my son to," she said. She spent about 50 hours developing the site in the last 30 days--grabbing an hour or so after she puts her 3-year-old son to bed. "But sometimes I get so engrossed that I'll work till 2:00 in the morning," she said.

Votava's day job--working on control systems for the ILC--is a bit like her new pastime. "For me, all problems at that level are logic problems," she said. "What is my goal? What is the best way that I'm going to go about doing that? It's the problem solving that I think is the same." Votava built in "cool, geeky" features, like links to Metra schedules for each nearby station and a map of Warrenville that can be moved within the picture frame on the homepage. Hotlinks take the visitor outside of Warrenville, to places like the vintage Paramount Theater in Aurora, hayrides at the Danada Equestrian Center, and the Green County Cheese Days Festival in Wisconsin. "I'm just hoping it will help people in the community realize what is going on," she said. "And I'm always open to suggestions."

Find cheese festivals, catfish-cleaning lessons and more on Votava's website.

Zoo Event
In response to yesterday's zoo event story, we received the following letter....

Dear FT:
Here is my contribution to the "zoo event" nomenclature. The term was used quite a bit when I was a graduate student in Berkeley, almost 50 years ago, working in bubble chamber physics. We had a collection of events which were not readily explicable. Luis Alvarez, our mentor, urged students frequently to look at the zoo events to look for possible new physics. Actually, the muon induced fusion was discovered by looking at zoo events.

Retirement: Priscilla Meldrim, a Public Information Specialist in the Education Office, retires tomorrow after 11 years of service. She will be replaced by docent Sue Sheehan. "I'm going to miss our conversations, her sense of humor and her really positive attitude and support," said colleague Nancy Lanning. "But I look forward to working with Sue, too. She's a hoot."

In the News
Brookhaven Laboratory News, August 30, 2006:
Nobel Laureate Melvin Schwartz Dies, August 28
Co-Discovered the Muon Neutrino at Brookhaven Lab in 1962
UPTON, NY - Melvin Schwartz, co-winner of the Nobel Prize in Physics, died on August 28, in Twin Falls, Idaho, after a long struggle with Parkinson's disease. In 1962, Schwartz, with Leon Lederman and Jack Steinberger, at the time all of Columbia University, discovered the muon neutrino at the Alternating Gradient Synchrotron (AGS), the then brand-new accelerator at the U.S. Department of Energy's Brookhaven National Laboratory. The three researchers shared the 1988 Nobel Prize for this discovery.

Summing it up
DZero collaborators who participated in the Manchester workshop.
Last week, the DZero collaboration met in Manchester, UK for their yearly workshop. This retreat serves as a time to set goals for the coming year and to evaluate how well things have progressed since the last meeting. As the Tevatron enters Run IIb, the 2006 DZero workshop has set the stage for an exciting year of physics, with over 130 talks presented. The themes of the meeting centered around physics analysis, algorithms at high luminosity, and commissioning of the detector and trigger upgrades.

At the end of the Tevatron shutdown in early June, the DZero detector was prepared to begin Run IIb with an upgraded Level-1 triggering system to handle the higher Tevatron luminosities of Run IIb and a newly installed inner "Layer-0" silicon microstip tracker to improve tracking and vertexing. Despite these challenges, the dedicated detector and operations experts were able to have the DZero experiment recording data within the first half hour of delivered beams in Run IIb. The DZero data-collection efficiency has rapidly returned to the high levels seen prior to the early 2006 shutdown.

Run IIb of the Tevatron has also forced a change in how data will be analyzed at DZero. The higher luminosities represent a significantly changed data collection environment, with more proton-antiproton interactions and thus, more activity in the detector. The algorithms used to identify different particles are being adapted for these new conditions.

2006 has been a very successful year for DZero. To give just a couple of examples, it achieved the first direct two-sided bound on the Bs oscillation frequency and obtained first evidence for the associated production of W and Z boson pairs in proton-antiproton collisions. With all of the developments described above, DZero is anticipating an even richer physics harvest in 2007 with a 2fb-1 data set (roughly twice the current amount). A broad range of results will benefit greatly from the increased statistics.

The successful operation of the DZero Silicon Microstrip Tracker depends upon the contributions of a team of experts, as well as support personnel.

NALWO Picnic
NALWO will hold a fall picnic on September 15, from 5:30 to 8:00 p.m. just outside the Kuhn Barn. Meet friendly lab families and join us for an evening of supper and games. Children are welcome; each family gets a Fermilab frisbee. Please bring food to grill, and a dish to share among 8 people, such as a casserole, salad or side dish. NALWO will provide charcoal grills, plates and cutlery, soft drinks and desserts. For additional information, contact the Housing Office, 630/840-3777 or housing@fnal.gov; Rose Moore, 630/208-9309 or Christiane Albrow, 630/717-8906.

Weekly Time Sheets Due Tomorrow
Due to the holiday on Monday, weekly time sheets are due in Payroll by 10:00 a.m. on Friday, September 1.

English country dancing
English country dancing will next meet on Sunday, September 24, at 2 p.m. in Kuhn Barn. The meeting date will change to the first Sunday of the month, beginning in November. Newcomers are welcome; partners and previous experience are not required. Please contact folkdance@fnal.gov or call 630-584-0825 or 630-840-8194.
