Axion space

Flashback Friday: In February 2018, scientists working on quantum sensor R&D to search for axion dark matter rejoice in their new space in Lab B. Among them is the late, great Alvin Tollestrup, second from right. people Photo: Leticia Shaddix

Scientists on the Holometer experiment measure tiny differences in the path lengths of two bright beams of light to measure a hypothesized “holographic noise” in the universe. Here, the glowing beam spots appear on a monitor in the Holometer experimental area. Photo: Robert Lanza, University of Chicago Last month the Holometer, Fermilab experiment E-990, reached its design luminosity, building up more than 1 kilowatt of infrared laser power stored in a 40-meter-long Michelson interferometer. This light intensity corresponds to more…
