South Korea's KRISS Refines Strontium Frequency 50 Times More Precisely
Original: After 88 Years, KRISS Redetermines a Key Strontium Frequency with 50 Times Better Precision | Newswise
South Korea's Korea Research Institute of Standards and Science has redetermined the strontium optical transition frequency, a key reference for optical atomic clocks, roughly 88 years after it was first measured. The new value is said to be 50 times more precise, improving the accuracy of timekeeping standards and precision measurement research worldwide.
Why now: A national metrology institute has announced a major improvement in a fundamental frequency standard used in optical atomic clocks.
