Abstract :
We have studied the accuracy of the atomic microwave power standard. The atoms are cooled and kept in a magneto-optical trap (MOT), then dropped through a terminated transmission line (a rectangular, R-70 type, waveguide). The measurement of the internal atomic state allows an accurate determination of the transmitted microwave power
