Abstract :
The first observation of Ramsey fringes is reported for NRC-FCs1. Preliminary measurements of the atomic temperature, sensitivity on launch angle and stability of the error signal are also presented. Work is underway to increase the contrast of the Ramsey fringes and improve the signal to noise ratio by using the state selection cavity, completing the detection region, demagnetizing the shields, and decreasing the atomic temperature.
