School takes hands-on approach to particle detectors

Employees wandering the halls of CERN early this month overheard some unusual exchanges: teachers encouraging students to break their equipment.

Eighty-eight students attended EDIT2011, the Excellence in Detectors and Instrumentation Technologies school. They had a unique opportunity to hold, manipulate and sometimes destroy sensitive devices usually buried out of reach in the centers of multi-ton particle detectors.

In a laboratory dedicated to silicon detectors, teachers challenged students to break diminutive wire connections with a needle.

“The needle looked massive through the microscope lens,” said Aria Soha, Fermilab’s Test Beam Facility manager, who attended the school. “I felt like Godzilla. But it really showed you how sensitive the detectors are.”

Particle physics experiments today require complicated machines that scientists design and build over the course of decades. These timelines pose problems for students trying to understand the inner workings of the detectors they use.

“When I was a student, experiments consisted of a small group of people,” said CERN physicist Ariella Cattai, director of the EDIT school. “We built, assembled and tested equipment ourselves.”

EDIT2011 is the first school in high-energy physics dedicated to giving students hands-on experiences with cutting-edge technology. More than 250 people applied. Accepted students traveled to CERN from 26 countries, and more than one third were women.

About 110 experts from 13 countries lectured or gave the students almost individual attention during labs over the course of two weeks.

Both Fermilab Director Pier Oddone and CERN Director-General Rolf Heuer said they were impressed with the school after touring some of the labs. Oddone supported the idea of hosting its next iteration at Fermilab.

“I think this fills a need,” Oddone said. “We should almost make it a necessary condition of getting your Ph.D.”

World's largest atom smasher to awaken after winter snooze

From Live Science, Feb. 17, 2011

When the world's most powerful atom smasher comes back online this month, scientists are hoping for great things, including possibly the discovery of nature's most sought-after particle – the Higgs boson.

The Large Hadron Collider (LHC), a 17-mile long (27-km) underground ring near Geneva where researchers speed up subatomic particles and crash them into each other, is due to start up again Feb. 21 after a winter hiatus. The break allowed engineers to perform maintenance and repairs on the machine's sensitive superconducting magnets, which cause charged particles to accelerate along the loop.

When it starts up again, LHC will work up to more powerful levels than reached before, creating more collisions and more data that could reveal new secrets of the workings of the universe.

"Our job here is to try to understand the fundamental building blocks of nature and what are the rules for putting them together," said physicist Aaron Dominguez of the University of Nebraska, a member of LHC's Compact Muon Solenoid (CMS) experiment, during a Wednesday (Feb. 16) National Science Foundation press conference. "If we find the Higgs boson in the next few years, it's not immediately clear to us how this new knowledge of how the world works is going to benefit us." But the finding could have profound ramifications for science and technology, he said.

ES&H Tip of the Week:

Watch for suspect and counterfeit items

Counterfeit items can make it into all levels of supply chains. Be vigilant in checking any items you receive and use. Photo: Courtesy of the Department of Energy

Suspect and counterfeit Items (S/CI) have made their way into nearly all facets of our lives, from the ink cartridges that we buy online to electrical equipment installed at Fermilab.

The risk of using substandard counterfeit items continues to grow due to the high profits realized by counterfeiters. During a recent visit to a local, national chain hardware store, all hoisting hooks observed on display were suspect, based on their markings.

Counterfeit items can make it into all levels of supply chains. Purchasing items from reputable suppliers helps reduce the risk, but the potential remains that suspect and counterfeit items may be introduced by a producer without the direct supplier knowing. There have been numerous cases of well-known manufacturers being deceived by their own suppliers, resulting in major product recalls. While many suspect items have been identified at Fermilab, we have been fortunate that there have been no known injuries or serious mishaps to date.

It’s important to know the general indications that an item might be counterfeit and to be vigilant checking any items that you receive and use. Poor workmanship, reworked material, and nonstandard or misspelled labeling are all indicators that the item you have received may be counterfeit. Carefully inspect any at-risk items before using them and seek guidance if in doubt.

If the price for an item seems too good to be true, it probably is.

Know your suppliers and consult with Procurement if needed. Make sure that employees who conduct inspections when receiving and installing the item have taken Fermilab suspect and counterfeit items training. Be especially careful when making Pro Card purchases, as these may bypass normal Procurement oversight.

Fermilab’s suspect/counterfeit program provides guidance for recognizing counterfeits and the items most prone to counterfeiting. The Department of Energy also posts identification information and relays information on counterfeit items found within the DOE complex.
