To a non-physicist, an “atomic beam collimator” may sound like a phaser firing mystical particles. That might not be the worst metaphor to introduce a technology that researchers have now miniaturized, making it more likely to someday land in handheld devices.
Today, atomic beam collimators are mostly found in physics labs, where they shoot out atoms in a beam that produces exotic quantum phenomena and which has properties that may be useful in precision technologies. By shrinking collimators from the size of a small appliance to fit on a fingertip, researchers at the Georgia Institute of Technology want to make the technology available to engineers advancing devices like atomic clocks or accelerometers, a component found in smartphones.
“A typical device you might make out of this is a next-generation gyroscope for a precision navigation system that is independent of GPS and can be used when you’re out of satellite range in a remote region or traveling in space,” said Chandra Raman, an associate professor in Georgia Tech’s School of Physics and a co-principal investigator on the study.
