| Denisov sees opportunities as DZero spokesperson | ||
|
||
|
Dmitri Denisov believes that now is a great moment for the DZero experiment.
"I think enthusiastic, talented physicists should be attracted to DZero at this time, because they can get started on physics right away here," he said.
Denisov should know. Recently elected DZero spokesperson, he has spent most of his life as a physicist on the experiment. Denisov received his BS in physics from Moscow Physical Technical Institute in Russia, and his PhD at the Institute for High Energy Physics in Protvino. He began working at DZero as a graduate student during Run I construction, and has since been leader of the DZero muon group, run coordinator, co-convener of the DZero electroweak physics group, Deputy Chair of the Institutional
Board and co-author of a number of DZero results, among other things. Denisov will assume his new role late this summer, when current spokesperson Jerry Blazey steps down, and will serve alongside
continuing spokesperson Terry Wyatt.
"I have gone from being a grad student, to a post-doc, to a senior collaborator. I've tried just about every role possible here," said Denisov. Such varied experience should give Denisov a major advantage as spokesperson.
Denisov imagines that recruiting will be one of his biggest challenges as DZero moves into the LHC era. "With the LHC starting up, we expect a considerable decrease in manpower devoted to DZero in the next 2 to 3 years. We have to plan for that now." Denisov noted recent DZero discoveries such as the first measurement of B_s oscillations and remarked on the potential for even greater discovery within the one inverse femtobarn of data to be sifted through and analyzed. "There is so much potential," he said. "I plan to advertise that during my term."

Ruler to Measure Universe - Biggest Ever 3-D Map A team of astronomers led by Nikhil Padmanabhan and David Schlegel has published the largest three-dimensional map of the universe ever constructed, a wedge-shaped slice of the cosmos that spans a tenth of the northern sky, encompasses 600,000 uniquely luminous red galaxies, and extends 5.6 billion light-years deep into space, equivalent to 40 percent of the way back in time to the Big Bang.
Schlegel is a Divisional Fellow in the Physics Division of Lawrence Berkeley National Laboratory, and Padmanabhan will join the Lab's Physics Division as a Chamberlain Fellow and Hubble Fellow in September; presently he is at Princeton University. They and their coauthors are members of the Sloan Digital Sky Survey (SDSS), and have previously produced smaller 3-D maps by using the SDSS telescope in New Mexico to painstakingly collect the spectra of individual galaxies and calculate their distances by measuring their redshifts.

| It has been one week since the zebra mussels that had taken over Fermilab's water cooling system were treated with EVAC. Now maintenance personnel are flushing the pipes to clear out the dead mussels. But fish have also been affected by the slimy substance designed to coat the mussels' gills. "The fact that we had some fish killed was not completely unexpected, but we tried to minimize it as much as possible," said Eric Mieland of Fermilab's Environmental Protection Group. FESS received permission to treat for zebra mussels using EVAC from the Illinois Environmental Protection Agency.
Roads and Grounds has collected approximately 250 dead fish from Bulrush Pond, and some dead fish were found at the Proton Return Ditch, said FESS Environmental Officer Rod Walton. More fish can be killed during a typical winter freeze, or during hot summers when high water temperatures decrease the amount of oxygen in the ponds. Still, FESS hopes to reduce the effects of EVAC on the fish the next time the zebra mussels get out of hand. "This was our trial - we were observing how the flows work. We now know where the trouble spots are and have a better idea of how to balance the flow and distribute the EVAC more evenly," said FESS Engineer Anne Lucietto. Nalco, the manufacturer of EVAC, has assured Fermilab that eating fish caught from affected ponds is safe for humans and wildlife, Lucietto said.
Maintenance personnel will continue to flush out the pipes until the end of the month, when startup of the Tevatron begins. The dead mussels will be piled near the sites where they were retrieved, so that engineers can track how extensively each part of the system was infested with the mussels before they are picked up by Roads and Grounds. If you come across a pile of the rotting mussels, Lucietto says, "don't mess with them. If you do, you'll get a noseful."

| Le Vent du Nord, June 10 | ||
|
||
| Le Vent du Nord is a group of four musicians who alternately use "diatonic accordion, bones, mandolin, jaw harp, step dance, hurdy gurdy, piano, piano-accoridan, bodhran, guitar and vocals" to belt out traditional French folk songs. Du Nord's liveley performances have scored rave reviews, and their albums have won international awards, such as the 2004 JUNO Award for Roots and Traditional Album of the Year. "One can easily imagine a French drinking party of the 15th century belting out the same refrains," wrote reviewer Christopher Hyde in the Portland Press Herald.
You can see Le Vent du Nord Saturday, June 10 at 8 p.m. in the Ramsey Auditorium. Tickets and more information and can be found here.
