NIST Hybrid Cooler Attains 2 Kelvin

By CSA Editor Online — NIST scientists have devised a novel hybrid system for cooling superconducting nanowire single-photon detectors (SNSPD). It uses a pulse-tube refrigerator cooled to 10 Kelvin (K) to precool a Joule-Thomson cryocooler that can then reach 2

NIST Physicists Squeeze Light, Cool Microscopic Drum Below Quantum Limit

By CSA Editor Online — Physicists at the National Institute of Standards and Technology (NIST) have cooled a microscopic mechanical drum to less than one-fifth of a single quantum, or packet of energy. The result, according to the research team,
