Energy Secretary Steven Chu urges U.S. to focus on R&D

Energy Secretary Steven Chu spoke of the rich history of Fermilab and the field of high-energy physics in his public lecture at the 44th annual Users’ Meeting on Thursday, June 2. In his lecture, titled “Revving up the great American research and innovation machine,” Chu said the U.S. must continue to invest in science and technology research and development, especially during tough economic times, to remain competitive as a world leader in the energy revolution.

Cryomodule Test Facility fridge cool on many levels

Flexibility isn’t usually the first thing you look for in a refrigerator.

But Fermilab’s future Cryomodule Test Facility (CMTF) refrigerator, recently approved for construction by DOE, is being designed as a one-size-fits-many cryogenic plant for the laboratory’s future superconducting radio-frequency research projects.

“Versatility is the prime objective of the new cryoplant,” said Arkadiy Klebaner, technical manager for the CMTF refrigerator project.

It will use superfluid helium to cool SRF cavities to 1.8 Kelvin while providing a variety of thermal shields by flowing helium at just the right temperatures.

As a bonus, it will also be several times more energy efficient than any superfluid helium cryogenic system currently in operation at the laboratory.

The key is the hybrid design of the pumping system, which uses both warm and cold pumping cycles to cool helium.

Fermilab’s current systems use only warm pumping, which brings ultra-cold liquid helium back up to ambient temperature before re-cooling it as it’s cycled through the experiment.

With the addition of cold pumping, the CMTF refrigerator can recycle cold helium without first warming it, so less energy is required to cool it back down. The hybrid cycle also allows it to pump helium through a wide range of operational loads.

Combining the old with the new, the design also incorporates the Tevatron’s compressors and storage tanks, reengineered to cool helium to 1.8 Kelvin.

Custom made for Fermilab’s SRF facilities, the refrigerator will serve as a cryogenics training ground for technicians and engineers.

“We’re excited for the fulfillment of a project that’s the result of the shared vision and effort of many people over the last eight years,” Klebaner said.

The CMTF refrigerator will be commissioned in the spring of 2013.

Energy secretary says Fermilab funding must be found

From the Daily Herald, June 3, 2011

Fermilab’s plans for the future are on solid ground, Energy Secretary Steven Chu said at the research facility Thursday night. But funding those plans is an immediate problem that will take some convincing on a national scale, he said.

Chu delivered a speech on the importance of scientific research in the everyday lives of Americans at Fermilab Thursday. His appearance was part of an annual event where scientists at Fermilab put their accomplishments on display for the world to see.

New monthly integrated luminosity record

Fermilab's Accelerator Division reached a new monthly integrated luminosity record in May. The new record, which was an average integrated luminosity of 286.204 inverse picobarns, supersedes the old record of 272.720 inverse picobarns set in March 2010.

Quarks and quantum quirks

From the Chicago Tribune, June 1, 2011

New book explains physics with breezy ease

While reading a book on contemporary physics some time ago, I realized that attempting to comprehend it was like trying to floss the teeth of a flea.


While drunk.

With broken fingers.

And blindfolded.

I managed to finish the book, but the moment I closed it, I had the feeling that everything I'd just stuffed in one ear was dribbling out the other side.

You won't feel that way after reading "Quantum Physics for Poets" (Prometheus), a sparkling and articulate new account of how the quantum revolution changed 20th century science — and, as a further delight, how physics and poetry can speak the same language.

At the Printers Row Lit Fest, sponsored by the Tribune, I'll be talking with the book's co-author, Christopher T. Hill, who heads the theoretical physics department at Fermilab in Batavia.
