WebbAlmost 20 years ago, in 1969, the well-known primary atomic clock CS1 of the PTB was put into operation, and it has been in continuous operation since 1978. In 1985, a second device, CS2, was completed. The intercomparison data of the CS2 versus CS1 will be presented in section 2.
WebbThe PTB CS1 belonged to the group of so-called primary standards of frequency and time since 1969. It was intermittently operated until 1978 and used for the steering of PTB's atomic time scale. Between 1978 and 1995 the CS1 was operated continuously as a clock. Throughout all the small chippers for home useWebbThe thermal beam primary clocks CS1 and CS2 continue to be operated as backup frequency references for the realization of the time scales UTC(PTB) and TA(PTB).
