Canadian scientists get more light in deal with the US Argonne National Laboratory

Canada’s synchrotron, Canadian Light Source (based in Saskatchewan), has signed a new three-year deal with the US Dept. of Energy’s Argonne National Laboratory’s Advanced Photon Source (APS)  that will give Canadian scientists more access to the APS facilities, according to the June 18, 2012 news item at the  Nanowerk website,

Seeking to solve some of today’s greatest global problems, scientists using x-ray light source facilities at national research laboratories in the United States and Canada are sharing more expertise.

The Canadian Light Source (CLS) and the Advanced Photon Source (APS) at the U.S. Department of Energy’s (DOE’s) Argonne National Laboratory agreed in January 2012 to a Partner User Proposal that cements a stronger working relationship between the two facilities for the next three years. These two premier light sources use different but complementary x-ray techniques to probe materials in order to understand chemical and structural behavior.

Tone Kunz’s June 18, 2012 news release for the APS provides details about the deal,

This new agreement will provide Canadian scientists with more research time to use the x-ray light source facilities and more time on a larger number of APS beamlines. Using varied x-ray and imaging capabilities will broaden the range of experiments Canadians may undertake at the APS to augment their research done at the Canadian Light Source. X-ray science offers potential solutions to a broad range of problems in surface, material, environmental and earth sciences, condensed matter physics, chemistry, and geosciences.

Since the Sector 20 beamlines became fully operational, scientists from Canada and other areas who have used these beamlines at the APS have produced an average of 51 scientific publications a year. This research includes the study of more effective mineral exploration strategies, ways to mitigate mine waste and mercury contamination, and novel ways to fabricate nanomaterials for use in fuel cells, batteries, and LEDs.

I had not realized how longstanding the  CLS/APS relationship has been,

Before the Canadian Light Source began operation in 2004, a Canadian group led by Daryl Crozier of Simon Fraser University, working in partnership with colleagues at the University of Washington and the Pacific Northwest National Laboratory, helped found the Sector 20 beamlines at the APS as part of the Pacific Northwest Consortium Collaborative Access Team, or PNC-CAT. Parts of this team were included in the X-ray Science Division of the APS when it was formed.

This long-standing partnership has led to scientifically significant upgrades to the beamline. The new agreement will provide the valuable manpower and expertise to allow the APS to continue to push the innovation envelope. [emphasis mine]

As I was reading Kunz’s news release I kept asking, what’s in it for the APS? Apparently they need more “manpower and expertise.” Unfortunately, their future plans are a little shy of detail,

Scientists from the APS and the Canadian Light Source will work together on R&D projects to improve light-source technology. In particular, scientists will upgrade even further the two beamlines at Sector 20 in four key areas. This will provide a unique capability to prepare and measure in situ films and interfaces, a new technique to create quantitative three-dimensional chemical maps of samples, and improved forms of spectroscopy to expand the range of elements and types of environments that can be examined.

What are the four key areas? For that matter, what is Sector 20? I suspect some of my readers have similar questions about my postings. It’s easy (especially if you write frequently) to forget that your readers may not be as familiar as you are with the subject matter.

(I wrote about the CLS and another deal with a synchrotron in the UK in my May 31, 2011 posting.)

Inspiring kids, again? High schoolers at Argonne National Laboratory

C. P. Snow’s 1959 lecture and book, Two Cultures, spends a fair chunk of time on the issue of encouraging the next generation to study science and engineering. As Snow perceived the problem, the UK was falling behind both the US and Russia in the science race. I haven’t investigated what the perceptions were in the US and Russia at the time but I have noticed that descriptions of the race to get someone on the moon feature a great deal of anxiety in the US about Russian supremacy in science. Given human nature, I imagine the Russians were worried too. Plus ça change, n’est ce pas?

Today, everyone is worried that someone else is going to get there (wherever that might be) first and there is enormous pressure internationally to inspire the next generation to pursue science, technology, engineering, and mathematics (STEM) careers.

I see that the Argonne National Laboratory in the US has opened up its doors to high schoolers for a special programme. From the June 6, 2012 news item by Tona Kunz on Nanowerk,

In commencement speeches across the country, graduates have , been warned to expect rocky times breaking into the workforce. Unemployment hovers between 8 and 9 percent. Competition is tough.

Unless you studied science or engineering. Those jobs have a 2 percent unemployment rate, which has led some Fortune 500 companies to complain about offices they can’t fill.

So it’s no surprise that when the U.S. Department of Energy’s (DOE) Argonne National Laboratory decided to give high school students a chance to test-drive a science career, it found students, parents and school officials from Naperville, Ill. eager to hop on board.

Kunz’s June 6, 2012 news release on the Argonne National Laboratory website mentions (Note: I have removed links from the excerpt),

…  Teachers received training in the workings of the Advanced Photon Source (APS), the brightest high-energy X-ray machine in the Western Hemisphere, and the Electron Miscroscopy Center (EMC). Students from Naperville’s two high schools then competed for slots on four research teams that used X-ray beams to decipher what matter is made of, how it’s built and how it reacts.

More than 5,000 researchers from throughout the world use the APS and EMC annually to target society’s greatest challenges: how to make better pharmaceuticals, sustainable fuels and high-performance materials. These challenges will feed scientific jobs for decades to come.

“I think there is a huge push in our district from the community for STEM (science, technology, engineering and math) education,” said Tricia Noblett, a teacher and science club advisor at Neuqua Valley High School. “I think they are seizing on what has been out there in the media that STEM fields are where the jobs are and that science careers can be interesting.”

Students drew on experiences in their lives to choose research topics and explained their results to scientists at the annual meeting held in May at Argonne for users of the APS, EMC and Center for Nanoscale Materials (CNM).

Inspired by the recent cleanup of a contaminated portion of the west branch of the DuPage River near their school, one group of students studied how to increase the efficiency of water filtration systems.

Another group worked with the Naperville wastewater facility to evaluate how corrosion affects the lifespan of water pipes.

And another group looked at how to improve the efficiency of graphene, a nanomaterial that may hold the key to building faster semiconductors for smart phones and the next-generation of research tools.

It’s exciting stuff and I’m always glad to have a chance to pass on information about these kinds of programmes. As for the history, I find it interesting to note the similarities with and the differences from the past.
