Description

Details on size and construction of the atomic clock, developed at the National Bureau of Standards, appear in this general view of the back of the equipment. B. F. Husten (left) and E. D. Heberling (right), members of the NBS Microwave Standards Laboratory staff, are shown making adjustments on the clock's amplifier and power supply circuits. The amount of equipment shown is larger than needed for the clock alone since some of the instruments are for measurements and performance tests. The circuits essential to the operation of this atomic clock could be condensed into one of the two cabinet racks.
