Profile: Jamie Ray, a high schooler on the Higgs hunt

Jamie Ray, a 2009 graduate of the Illinois Math and Science Academy, works with Craig Group at CDF.

When Jamie Ray arrived at the CDF trailers at the start of 11th grade, he was a little overwhelmed.

"Back then, all I knew about particle physics was from books," he said, "and books don't talk about sitting down with a million events to analyze."

That was nearly two years ago, on Ray's first day in an independent research program for students at the Illinois Math and Science Academy, the magnet high school that Fermilab Director Emeritus Leon Lederman founded in 1985. Through IMSA's Student Inquiry and Research program, Ray signed up to spend every Wednesday analyzing CDF experiments with a Fermilab scientist.

It didn't take long for Ray to get over his intimidation and get to work. His mentor, CDF scientist Craig Group, was confident that the Ray and fellow IMSA students would make valuable contributions to Fermilab research.

"We don't give them projects we've already worked out, so we learn a lot from the problems they run into," Group said. "We're trying to understand things at the same time that they are."

After a few weeks of learning computer programming languages, Ray delved into some data on his own, initially focusing on Z boson decays. In the summer after his junior year, Ray worked full-time at CDF.

"What sets Jamie apart is that he's not afraid of a hard problem," Group said. "He's happy to spend all day on a difficult project without getting frustrated."

During his senior year, Ray's focus shifted to one of the hottest topics in modern science -- the hunt for the Higgs boson. His name will appear as a co-author on an upcoming Physical Review Letters paper about that search.

In the fall, Ray will head to Stanford University. Picking a major won't be easy -- Ray's interests stretch from engineering to history to philosophy -- but physics is a possibility, he said. In any case, he will not forget his time at Fermilab.

"At first, I didn't think I'd be able to make a meaningful contribution," he explained. "It's satisfying to know I've done useful work here."

Special Announcement

Window washing begins today

Interior and exterior Wilson Hall window washing will take place for most of the remainder of August.

Crews will wash exterior windows during phase one of the schedule beginning today and extending through Friday.

Phase two of the schedule will begin Monday, August 10, and will include interior window-washing, including double-paned windows. Crews will work from the top floors down, beginning with floors 15 and 14 on Monday, 13 and 12 on Tuesday, 11 through eight on Wednesday, seven through four on Thursday and three through one on Friday. Phases three and four of the schedule will take place during the week of Monday, August 17, and include the mezzanine and ground floors. Crews will wash the windows in Wilson Hall's atrium during nights the week of August 17.

Please clear all items from in front of windows on days work is scheduled for your floor. Contact Enixe Castro at x2798 with any questions.

Hunting for neutrinos in Minnesota

From DOE Office of Science American Recovery and Reinvestment Act Newsletter, July, 2009

Construction crews began digging at the future site of the NOvA neutrino detector facility in Ash River, MN, on June 1. The facility is designed to detect neutrinos originating at DOE's Fermi National Accelerator Laboratory (Fermilab) 500 miles away in Batavia, IL.

The Recovery Act provided funds for the civil construction project.

"It's pretty much earth work now," said Davin "Buddy" Juusola, senior project manager for Adolfson & Peterson. But once the dirt is cleared, the construction crew will face the Canadian Shield, a mass of 2.7 billion-year-old Precambrian rock that stretches 3 million square miles across Canada and dips into a small northern edge of the U.S.

ES&H Tips of the Week - Environment computersecurity

Reducing the use of ozone-depleting substances

The annual ozone hole over Antarctica in 2005 reached its largest area on Sept. 11. Observations are from the Ozone Monitoring Instrument on NASA's Aura satellite, launched in 2004. Blue and purple areas represent low ozone levels. The U.S. is continuously working to reduce the number of ozone-depleting substances in the atmosphere. Credit: NASA

A positive environmental story has been the ongoing reduction in ozone-depleting substances in the atmosphere.

More than 40 years ago, the United States began replacing chlorinated hydrocarbon refrigerants such as FreonT with compounds that had less ozone-depleting potential, or ODP. One of the most popular of these compounds is R-22, a refrigerant that has largely replaced the older generation of refrigerants.

However, R-22 is an interim step. It still has some ODP, and it also has potential as a greenhouse gas. Provisions in the Clean Air Act mandate that eventually R-22 and similar compounds will be phased out and replaced with an entirely new class of refrigerants that have zero ODP. As of Jan. 1, 2010, no R-22 may be manufactured for new equipment. By Jan. 1, 2020, the manufacture of R-22 will be completely prohibited.

Fermilab is gradually updating its equipment to meet the upcoming Clean Air Act deadline. However, that is not simple because at Fermilab our need for power inevitably produces heat. We have hundreds of individual pieces of equipment, from massive chillers to small window air conditioners to keep things cool. For example, the Grid Computing Center requires more than 1,000 tons of air conditioning capacity to cool the data crunchers. To put that in perspective, an average house requires about 5 tons, so the GCC is the equivalent in cooling terms of about 200 houses.

Fortunately, in the design of cooling for the GCC, about 60 percent of the cooling is provided by equipment that uses the latest generation of refrigerants with zero ODP. A side benefit is that the newer equipment is more efficient, so there is a long-term savings in energy cost.

You can achieve a similar savings at home by converting your air conditioning equipment to use newer refrigerants, such as PuronT.
