Abstract:	This paper describes the performance of an atomic clock based on Coherent Population Trapping in a 87Rb vapor. The clock employs a small spherical glass cell and exhibits a performance which is comparable to that of a commercial atomic clock. A resonance width of less than 200 Hz leads to short term stability of 3×10-11/vt for time constants of 0.5 sec to 200 sec. The relative frequency stability is better than 10-10 with a slow drift of only 0.1 mHz per day.
