In Brief

Updated format for Fermilab Today begins today

Following the launch of the new format of the labwide calendar, which now can be viewed from mobile devices and is accessible from the Fermilab at Work Web pages, we are introducing changes to the layout of Fermilab Today.

Beginning today, we replace calendar listings with a link to the labwide calendar for readers to learn about events at Fermilab. As the most up-to-date snapshot of what's taking place at the laboratory, it is intended to serve as the primary resource for both scientific and nonscientific events at the laboratory.

In addition, announcements are featured in the left column of the newsletter, closer to the top of the layout. This way readers can see the latest and most important announcements without having to scroll to the bottom.

As a reminder, anyone with a Fermilab ID may submit announcements that are relevant to the Fermilab community. Anyone with a Services account can submit a calendar item in accordance with the stated guidelines. We will continue to post classifieds on Fridays.

The cafeteria and Chez Leon menus as well as the weather forecast have also been replaced with links to their corresponding online resources.

The LHC experiments

The Large Hadron Collider is the world's biggest particle accelerator, but it can only get particles moving very quickly. To make measurements, scientists must employ particle detectors. There are four big detectors at the LHC: ALICE, ATLAS, CMS and LHCb. In this video, U.S. CMS Education and Outreach Coordinator Don Lincoln introduces us to these detectors. View the 7-minute video.

Revved-up CERN collider aims to shed light on dark cosmos

From Reuters, March 12, 2015

(Reuters) - Scientists at the CERN physics research center said on Thursday the mystery dark matter that makes up 96 percent of the stuff of the universe will be a prime target for their souped-up Large Hadron Collider (LHC) in the coming years.

Tip of the Week: Sustainability

Maintaining a sustainable vehicle fleet at Fermilab

The operations and business of Fermilab require motor vehicles. From vans to pickup trucks to buses, each vehicle has a specific purpose. Fermilab evaluates the 193-vehicle fleet for efficiency on a routine basis. This contributes to decreasing Fermilab's overall carbon footprint.

Fermilab exceeds federal environmental regulations for fleet management. Our Site Sustainability Plan sets specific fleet management goals regarding increasing alternative fuel consumption, reducing petroleum consumption, and making all light-duty vehicle purchases alternative fuel vehicles. These goals are based on federal regulations.

Fermilab currently uses three types of fuel: unleaded gasoline, E85 and biodiesel. The fleet is predominantly light trucks: pickup trucks, small SUVs, and compact and full-size vans. We also operate approximately 20 heavy-duty trucks (fire trucks, tractors and dump trucks), a few medium-duty vehicles and four sedans.

Fermilab's Fleet Utilization Committee evaluates these vehicles and, in conjunction with grass-roots efforts, has significantly contributed to making the fleet its most efficient size. Transportation Services assists employees in procuring the right-sized vehicle for the job as well as ensuring the environmental requirements are met in the best way possible. The no idling policy also contributes to decreasing vehicle emissions.

The road to a greener fleet at Fermilab starts with reducing how much petroleum we use. To that end, we use gasohol (10 percent ethanol and 90 percent unleaded gasoline), E85 fuel and biodiesel. We also purchase flexible-fuel vehicles that use E85 fuel. These are the main alternative-fuel vehicles available as light trucks.

When we first began purchasing vehicles operating on alternative fuels, we didn't have the infrastructure to provide the alternative fuel for such vehicles. But with the assistance of some grant funding from DOE, we were able to add an E85 fueling system. At one time we operated vehicles that ran on compressed natural gas, and a collaboration with NICOR helped provide the needed infrastructure, but the bi-fuel compressed natural gas system was phased out as the manufacturers stopped selling bi-fuel trucks and supplying parts.

We have stayed the course with E85, biodiesel and a few hybrids. We look forward to the prospects of new-technology vehicles that will fit into our fleet. Vehicle fuels in our not too distant future will most likely include a new breed of electrics, plug-in hybrids, hydrogen, fuel cell and maybe even some high-tech pedal cars. Stay tuned!

Number-crunching the Higgs boson: meet the world's largest distributed computer grid

From The Conversation, March 12, 2015

The world's largest science experiment, the Large Hadron Collider, has potentially delivered one of physics' "Holy Grails" in the form of the Higgs boson. Much of the science came down to one number – 126, the Higgs boson's mass as measured in gigaelectronvolts. But this three-digit number rested upon something very much larger and more complicated: the more than 60,000 trillion bytes (60 petabytes) of data produced by colliding subatomic particles in four years of experiments, and the enormous computer power needed to make sense of it all.
