Abstract :
The accuracy evaluation of the optically pumped cesium beam frequency standard with a 37-cm long Ramsey cavity, KRISS-1, is being performed. Some major frequency shifts are evaluated; e.g., second-order Zeeman and Doppler shifts, cavity pulling, Rabi pulling, etc. The overall uncertainty is expected to be at the low 10/sup -13/ level in the KRISS-1.
