The Performance of Primary CS Beam Clocks Using Quadrupole and Hexapole Deflection Systems. Consequences for Time Keeping

Gerhard Becker

Abstract:	Since 1978 the time-and-frequency standard CS1 of the Physikalisch-Technische Bundesanstalt (PTB) has operated continuously as a "primary clock". Its uncertainty (7.10 ) is considerably smaller than that of the other existing primary standards. CS1 is equipped with a combination of quadrupole and hexapole magnets and uses a longitudinal C-field. Consequences of utilizing primary clocks of this quality for the generation of the International Atomic Time Scale TAI are discussed.
