dc.description.abstract We prepare number stabilized ultracold atom clouds through the real-time analysis of nondestructive images and the application of feedback. In our experiments, the atom number N similar to 10(6) is determined by high precision Faraday imaging with uncertainty Delta N below the shot noise level, i.e., Delta N < root N. Based on this measurement, feedback is applied to reduce the atom number to a user-defined target, whereupon a second imaging series probes the number stabilized cloud. By this method, we show that the atom number in ultracold clouds can be prepared below the shot noise level. eng
