The ptb primary clocks cs1 and cs2
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 WebbThe primary clocks CS1 and CS2 have been developed and operated by the Physikalisch-Technische Bundesanstalt, ... (CS1) and 12 × 10 -15 (CS2). Comparisons with PTB's cold-atom frequency standard CSF1 (u B = 1 × 10 -15 ) over 3.5 years revealed that CS2 and CSF1 agreed well within the uncertainty u B (CS2), whereas CS1 frequency ...

WebbBased on its research and development work, PTB provides a wide range of metrological services. The central task in this context – laid down by law – is to realize and to disseminate the units as accurately as possible. In this way, PTB ensures that uniform measures are used, not only in Germany, but throughout the world. WebbThe 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).
