Abstract
Various regimes of the loading of a magneto-optical trap formed near an atom chip, such as loading from thermal atomic vapors and from a low-velocity atomic beam, have been studied on an example of 87Rb atoms. The possibility of controlling the loading of the magneto-optical trap by spatially controlling the atomic beam has been demonstrated. This has made it possible to increase the loading rate of atoms into the magneto-optical trap with keeping ultrahigh vacuum near the atom chip. The maximum number of atoms in the magneto-optical trap at optimal loading regimes is 4.9 × 107. In this case, the measured lifetime of atoms in the magneto-optical trap is 4.1 s.
