The subatomic muon could reveal potentially disastrous pipe corrosion.

By: Charles Q. Choi, Contributor
(Inside Science) — Of all the parts of the nation’s infrastructure that one might want least to fail, nuclear power plants might rank the highest. U.S. nuclear power plants are on average more than 30 years old now, and pipes within them can corrode over time with potentially lethal results. Now researchers suggest they could noninvasively scan infrastructure for weak points with the aid of subatomic particles streaking down from the sky.

Water and steam pumped through a pipe in a power plant or industrial refinery can eat away one side of the pipe. In 2004, such corrosion led a pipe to break at Mihama Nuclear Power Plant in Japan, killing five people and injuring six others with super-hot high-pressure steam in Japan’s worst nuclear power accident until Fukushima.

Analyzing the structural integrity of pipes typically involves ultrasound and X-ray scans. READ MORE

1st proton collisions at the world’s largest science experiment expected to start the first or second week of June

First collisions of protons at the world’s largest science experiment are expected to start the first or second week of June, according to a senior research scientist with CERN’s Large Hadron Collider in Geneva.

“It will be about another six weeks to commission the machine, and many things can still happen on the way,” said physicist Albert De Roeck, a staff member at CERN and a professor at the University of Antwerp, Belgium and UC Davis, California. De Roeck is a leading scientist on CMS, one of the Large Hadron Collider’s key experiments.

The LHC in early April was restarted for its second three-year run after a two-year pause to upgrade the machine to operate at higher energies. At higher energy, physicists worldwide expect to see new discoveries about the laws that govern our natural universe. READ MORE

Why does physics matter? World’s scientists convene for ‘State of the Proton’

Starting Monday, the SMU Physics Department hosts more than 300 of the world’s leading experts on particle physics. The scientists will hold nuts and bolts sessions on questions that drive the world’s leading-edge physics experiments.

The “2015 International Workshop on Deep-Inelastic Scattering and Related Subjects,” is held annually in a world-class city, and this year is hosted by SMU at the Hughes Trigg Student Center.

Workshop sessions start Monday, April 27, and run through Friday, May 1, with physicists rolling up their sleeves to hash out equations, debate and refine algorithms, discuss and develop methodologies, explore spin physics and heavy flavors, and analyze and critique software and hardware developments to ensure the accuracy of the world’s frontline particle experiments.

SMU physicists and others at the workshop include members of the international collaboration that in 2012 made worldwide headlines for observing the Higgs Boson. The Higgs is science’s newest fundamental particle. Its presence was observed after high-energy collisions in the world’s most powerful particle accelerator, the Large Hadron Collider, which straddles France and Switzerland. READ MORE

On the same day, the University honored its best students at the 18th Honors Convocation. The address was delivered by Brian Stump, Claude C. Albritton Jr. Chair in Geological Sciences in the Huffington Department of Earth Sciences.

An expert in seismic wave propagation and earthquake source theory, Stump has become well known in North Texas for his continuing research on the increasing occurrences of small earthquakes that have shaken the area since 2008. In November 2014, he was named a Fellow of the American Association for the Advancement of Science for distinguished contributions to his field, particularly in the area of seismic monitoring in support of the Comprehensive Nuclear Test Ban Treaty.

Physicists tune Large Hadron Collider to find ‘sweet spot’ in high-energy proton smasher

Phys.org

Posted: April 15, 2015

Start up of the world’s largest science experiment is underway—with protons traveling in opposite directions at almost the speed of light in the deep underground tunnel called the Large Hadron Collider near Geneva.

As protons collide, physicists will peer into the resulting particle showers for new discoveries about the universe, said Ryszard Stroynowski, a collaborator on one of the collider’s key experiments and a professor in the Department of Physics at Southern Methodist University, Dallas.

“The hoopla and enthusiastic articles generated by discovery of the Higgs boson two years ago left an impression among many people that we have succeeded, we are done, we understand everything,” said Stroynowski, who is the senior member of SMU’s Large Hadron Collider team. “The reality is far from this. The only thing that we have found is that Higgs exist and therefore the Higgs mechanism of generating the mass of fundamental particles is possible.”
