Nebraska physicists track particles with pixels

CMS Forward Pixel Detector

Physicist Aaron Dominguez puts on a lab coat, head cover and booties. He opens the door to a clean room at CERN and enters a sterile zone with silvery walls and glossy floors. The room contains multiple cables, computing equipment and four long, white wooden boxes that house the Forward Pixel Detector, a key component of the CMS experiment.

Dominguez, along with his seven colleagues from the University of Nebraska, are readying the detector, nicknamed FPIX, for installation in the spring at the core of the five-story experiment at the LHC.

FPIX, comprises both ends of the cylindrical CMS detector and contains millions of tiny electronic sensors, or pixels, to track charged particles. FPIX can pinpoint particle locations to rectangular-shaped pixels comparable to the width of a strand of hair.

“The pixel detector is useful because its pixels are so small they can effectively be used to give you a precise three-dimensional point in space that the particle passed through,” Dominguez explained.

If many of the pixels fail, FPIX will lose its accuracy. So, the Nebraska team created a system of electronics and computer boards to test the detector one piece at a time.

“Since we could not manually test each of the 18 million channels (of data from FPIX), we had to come up with a more sophisticated way to do it,” Dominguez said.

Roughly 1,000 multiple-layered slabs, or plaquettes, make up the FPIX detector. Each plaquette contains 8,320 to 41,600 pixels.

In order to earn a passing grade from the Nebraska team, and a place in FPIX, the plaquettes had to pass several computer-administered tests done at Fermilab in close collaboration with Northwestern University and University of Milan.

P5 Meets at SLAC to discuss U.S. particle physics vision

From SLAC today,
Feb. 21, 2008

The Particle Physics Project Prioritization Panel (P5) meets at SLAC today through Saturday in the second of three cross-country meetings to aid in forming a new 10-year plan for U.S. particle physics.

By April, P5 will make a recommendation to the U.S. High Energy Physics Advisory Panel that takes into account the field's fluid nature and considers projects in different budget scenarios.

At the heart of the matter: The hunt for the God Particle

From National Geographic,
March 2008

If you were to dig a hole 300 feet straight down from the center of the charming French village of Crozet, you'd pop into a setting that calls to mind the subterranean lair of one of those James Bond villains. A garishly lit tunnel ten feet in diameter curves away into the distance, interrupted every few miles by lofty chambers crammed with heavy steel structures, cables, pipes, wires, magnets, tubes, shafts, catwalks, and enigmatic gizmos.

This technological netherworld is one very big scientific instrument, specifically, a particle accelerator-an atomic peashooter more powerful than any ever built. It's called the Large Hadron Collider, and its purpose is simple but ambitious: to crack the code of the physical world; to figure out what the universe is made of; in other words, to get to the very bottom of things.

Powering discoveries: Ranger set to fuel new era of scientific discovery

Researchers now have access to an unprecedented tool for extending knowledge: Ranger—the most powerful computing system in the world for open scientific research—entered full production on 4 February at the Texas Advanced Computing Center at the University of Texas at Austin, U.S.

Ranger’s deployment marks the beginning of the Petascale Era—where systems will approach a thousand trillion floating point operations a second—and will greatly enhance the computing capacity of the TeraGrid, becoming the largest HPC computing resource on the U.S-wide high performance computing grid. Ranger will offer more computer cycles for calculations than all other TeraGrid HPC systems combined.

Children's Summer Day Camp registration due
Registration forms for the onsite day camp for children of Fermilab employees are due by 5 p.m. Feb. 28. The camp for ages 7 through 12 consists of three separate three-week sessions: session I: June 16 - July 3, session II: July 7- July 25, session III: July 28 - August 15. The camp, held in the lower level of the Kuhn Barn in the village, runs from 7:30 a.m. to 5:30 p.m. You may choose any or all of the sessions. The fee for each day camp session is $295 per camper. A $125 deposit per session per camper must accompany the registration form. Registrations will be accepted at the Recreation Office, M.S. 126. Applications go into a lottery held on Feb. 29. An information booklet and registration form can be found on the Recreation Website.

Applications due for 2008 CERN-Fermilab Hadron Collider school
Applications for the 2008 CERN-Fermilab Hadron Collider Physics Summer School are due Feb. 29. The school takes place August 12-22, 2008, at Fermilab, and focuses on training advanced graduate students and young postdocs. Both theorists and experimentalists should apply. The list of lectures and lecturers has been posted at the school Web site.
