Veteran DZero scientist assumes co-spokesperson position

Paul Grannis

DZero has come full circle with the recent reelection of their first spokesperson Paul Grannis. Grannis joined DZero in 1983 and served as inaugural spokesperson, then co-spokesperson until 1996.

Grannis takes over from current DZero co-spokesperson Gregorio Bernardi on Sept. 1.

In his time at DZero, Grannis played fundamental roles in designing, building and commissioning the detector and generating the first round of physics results, including the observation of the top quark.

Nearly two decades later, he and current DZero co-spokesperson Dmitri Denisov are guiding the experiment to the finish line as they round out an eventful and memorable 31 years.

"I'd like to commend Gregorio Bernardi, who is stepping down as co-spokesperson," Grannis said. "He's done a fine job of steering the collaboration through many wonderful publications. In the future it will be my pleasure to serve as co-spokesperson again for DZero, and I'm looking forward to working with Dmitri."

In this final one-to-two year stretch, the collaboration has its sights set on finalizing the remaining papers and publishing results that will stand as legacy for DZero and the Tevatron.

Denisov says that, in this interesting and challenging period following the 2011 shutdown of the Tevatron, it's important for the collaboration to focus on the experiment's scientific analyses and for the leadership to develop well-defined goals while retaining the trust of the collaboration. Grannis, Denisov says, will be a great asset in setting and achieving these goals.

"Paul is a perfect match. He's really devoted and has always been driven by the science. He's taught many of us to follow the science, too," Denisov said. "I think everyone in the collaboration is really pleased with having Paul as our new co-spokesperson."

In Brief

Revised Procedures for Researchers document available online

A revised version of PFX, the document describing procedures for researchers at Fermilab, is now available online.

The new version of the document addresses the changes that have occurred since November 2012, when the previous version was released. Researchers and service providers are invited to send suggestions and corrections to in order to ensure it stays useful and up to date.

We are planning a further version this year to reflect the new organization changes and other comments that you may have.

In Brief

Free screening of "Particle Fever" - tomorrow at University of Chicago

You can catch "Particle Fever" tomorrow at 6:30 p.m. in Chicago. Fermilab scientists will be on hand to answer questions.

The University of Chicago will host a free screening of "Particle Fever" on Tuesday, Aug. 26, at 6:30 p.m. Fermilab Deputy Director Joe Lykken and scientist Marcela Carena of Fermilab and the University of Chicago will be among the speakers at a post-screening Q&A session.

The screening will take place at the Reva and David Logan Center for the Arts at 915 E 60th St., Chicago.

Five reasons we think dark matter exists

From Medium, Aug. 19, 2014

Any recent article about the remaining mysteries of the Universe will include dark matter close to the very top of the list of unsolved problems. What is it? Where is it? And if it's there, how do we measure it? These are important questions still at the forefront of research in cosmology. But this elusive substance that affects the motion of our galaxy and is the reason that galaxies exist with the properties they have, has only been detected indirectly, and has yet to be measured via direct detection. Earlier this year, the most sensitive dark matter experiment to date, LUX, released its results showing no direct evidence for dark matter and failing to confirm potential detections by two groups of experiments, DAMA/Libra and CoGeNT and Super-CDMS.

"Big" sustainability

We are talking about the concept of "sustainability" more than ever these days, and the quotation marks around the word underscore the difficulty in understanding just what is meant by it. At its simplest, sustainability means managing resources now in a way that allows them to be replenished in time and in quantities sufficient to serve the future. It's sort of like not spending money faster than we make it.

Measuring sustainability usually focuses on energy and water conservation, recycling and reusing materials, and minimizing waste. If we value large, diverse biological ecosystems, we ought to strive to preserve them for the future. Conservationists know that the quality of the resources that we manage to preserve for future generations is as important as the sheer quantity. It is important to measure ecological resources carefully so as to include their qualitative as well as quantitative aspects.

Since Fermilab was built, the surrounding area has been developed into intensive residential, commercial and industrial activities. So if "open" or "green" space is a measure, we can claim a degree of success in that Fermilab's presence has preserved open space for the use of future generations.

But here is where the notion of quality becomes important. To the extent that the Fermilab site is an ecological entity, it's fair to ask about the quality of the green space. Over the years, Fermilab's land managers have evolved a stewardship philosophy in which the undeveloped resources of the site are managed in a more "natural" way to maximize the aesthetic and ecological values of the site.

That turns out to have some valuable side benefits. In many cases this approach to management is cheaper than more traditional, energy- and chemical-intensive and destructive methods. Another is that the resources after years of this approach to management are of higher ecological quality than they were 40 years ago.

The reconstructed tall-grass prairie on site is an example of how this management strategy can result in the preservation of not just open space, but a space that is biologically diverse, provides us and those in the future with ecological services, preserves the intrinsic values of natural ecosystems, and honors the natural history of the land where we are located. After all, before European settlers came to this area, about 1830 or so, the area was a rich mosaic of grasslands that reached from the prairies of the Dakotas and Iowa to lush wetlands and oak savannas.

So what does this have to do with sustainability? I'm suggesting that we think of sustaining not just the land, but also the quality of the ecological systems in it, and not just for its own sake, but for the use and enjoyment of future occupants and visitors of the Fermilab site.
