In 1952, NIST completed the first accurate measurement of the frequency of the cesium clock resonance. The apparatus for this measurement is named NBS-1. In 1955, the National Physical Laboratory in England built the first cesium-beam clock used as a calibration source. In 1959, the NBS-1 went into regular service as NIST's primary frequency standard. In 1960, NBS-2 was inaugurated in Boulder; it could run for long periods unattended and was used to calibrate secondary standards. It was one of the two cesium beam frequency standards that were in operation, making it possible to refer the national standard of frequency to an atomic resonance. It was accurate to within 1.5 parts in 10. Charles Snider of the Radio Standards Laboratory pours liquid nitrogen over a cold trap of the new cesium beam frequency standard as Roger Beehler adjusts the atomic beam detector. The U-shaped resonant cavity used to excite the cesium transition is suspended above the center of the machine. An atomic cloc...
