Laser-crystal sensor measures strong magnetic fields in challenging environments
Researchers at Sandia National Laboratories have patented a magneto-optical sensor, which uses a rare earth crystal and laser light to measure the strength of intense magnetic fields and electrical currents.
“We think this technology is a pretty major improvement in measuring magnetic fields,” said Israel Owens, a Sandia physicist and co-inventor of the sensor. “We think it’ll be essential especially for research in fusion, high-energy physics, and the power utilities industry. We’re really excited about where things are going.”

In the framework of the procedure governing the preparation and adjustment of France’s Plan VII, which is scheduled to cover the period from 1976 to 1980, an energy committee was appointed by the French government to survey the main lines of the energy policy from now until 1985, based on guidelines laid down in early 1975 by the government. The committee elaborated forecasts for 1985 and 2000 and, on this basis, developed propositions for an energy policy whose main features are a high energy savings program and an important development of nuclear energy.
