FIG. 2.

Typical time traces of fluorescence signal from a few-atom MOT. The magnetic-field gradient is in (a) and in (b) whereas the average number of atoms is 1.2 in (a) and 0.18 in (b). The current applied to the Rb dispenser was fixed at during the measurements.

FIG. 3.

Feedback in action. (a) Time trace of the magnetic-field gradient and (b) the fluorescence signal from trapped atoms. The field gradient can be changed with a rise/fall time of . The waiting time for one atom was about .

FIG. 4.

Results of the magnetic-field-gradient feedback. The atom number is fixed to one in (a), two in (b), and three in (c). Each histogram shows the occupation probability for the preset feedback atom number. Photon count rate corresponding to one atom is about .
