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. WebbPRIMARY TIME AND FREQUENCY REFERENCES PTB has continued to operate two primary frequency standards with a thermal atomic beam as clocks. The CS1 has a history of more than 30 years. It was refurbished about 4 years ago. The CS2 has been operated since 1986 with, up to now, the first charge of cesium (5 g) in each of the two ovens. photomechanics mac
