KTeV crystals to shine again

JPARC graduate students work to pack crystals from Fermilab's former KTEV experiment for shipment. JPARC will use the crystals in an experiment that will look for ultra-rare kaon decays.

From 1997 to 1999, scientists at Fermilab conducted an experiment using the most accurate energy-measuring device ever built for high-energy physics.

Then researchers carefully stored the experiment, KTeV.

Until now.

Graduate students from the Japan Proton Accelerator Research Complex, or JPARC, arrived last Wednesday to help package the 3,100 crystals stored in KTEV's detector for shipping to Japan. The detector's crystals are the key to its sensitivity. They are made of cesium iodide, a heavy and transparent compound that has the density to stop a particle and the ability to generate and conduct light. Scientists from JPARC will use the crystals at in an experiment complementary to those that will be performed at the Large Hadron Collider.

Researchers at JPARC will study ultra-rare kaon decays, outcomes that occur a few times in a hundred billion collisions.

"Rare decays are a very stringent test of the Standard Model," said Hogan Nguyen, PPD Technical Centers Department head. Learning more about the parameters of particle decay will help scientists better understand what they find in collisions in the LHC.

The KTeV experiment used the crystals to measure energy from photons and electrons, Nguyen said. When the particles enter the crystals, the interaction between the crystal and the particles puts the crystals into an excited state. As the crystals de-excite, they emit near-UV light. Photomultipliers measure the electric current the interaction generates.

Ray Safarik, a technical specialist at Fermilab, shows the partially dismantled KTEV detector.

Moving the crystals will save both institutions money. Sending the crystals to Japan relieves Fermilab of the responsibility of maintaining the sensitive crystals in a useable state and saves Japan from having to purchase new parts.

The materials that make up the detectors cost about $6 million in 1993, said Ray Safarik, a technical specialist at Fermilab who has been coordinating the move.

"They would cost considerably more today," he said. But transporting them to Japan for reuse costs less than $80,000.

The ongoing move began in spring of 2007.

The University of Chicago launches new research catalyst program

From University of Chicago Chronicle, Oct. 23, 2008

The University has launched the Arete Initiative, an intellectual incubator program designed to assist faculty in developing innovative, large-scale interdisciplinary research projects.

In announcing the initiative, Donald Levy, the Albert A. Michelson Distinguished Service Professor in Chemistry and Vice President for Research and for National Laboratories, wrote that Arete's primary purpose is "to remove the barriers to success by providing expertise in leading interdisciplinary teams" and ensure that investigators have the resources they need to produce "research innovations, advance what were thought to be intractable problems, influence multiple disciplines and spawn new scholarly fields."...

...Laboratory researchers interested in the possibility of establishing projects in conjunction with a University faculty member(s) through Arete may call (773) 834-9870 or e-mail arete@uchicago.edu. For more information, visit arete.uchicago.edu.

Catching quakes with laptops

Inside your laptop is a small accelerometer chip, there to protect the delicate moving parts of your hard disk from sudden jolts.

It turns out that the same chip is a pretty good earthquake sensor, too-especially if the signals from lots of them are compared, in order to filter out more mundane sources of laptop vibrations, such as typing.

It's an approach that is starting to gain acceptance. The project Quake Catcher Network (QCN), already has about 1500 laptops connected in a network that has detected several tremors, including a magnitude 5.4 quake in Los Angeles in July. Led by Elizabeth Cochran at the University of California, Riverside, and Jesse Lawrence at Stanford University, QCN uses the same BOINC platform for volunteer computing that projects like SETI@home rely on.

One of the benefits of this new technology is price: Research-grade earthquake sensors typically cost between $10,000 and $100,000. Of course, they are much more sensitive, and can detect the subtle signals of far-away quakes that laptops will never pick up. But Lawrence notes that, "with many more cheap sensors, instead of guessing where strong motions were felt by interpolating between sensors, we should be able to know where strong motions were felt immediately, because we have sensors there."
