The first microchip atomic trap, designed at the Institute for Laser Science, Japan. The structure of wires is painted with gold at the insulator substrate. The main wire has Z-shape; the magnetic field allows the trapping of neutral atoms due to their magnetic momentum. The ship has sizes 2 x 2 cm. It was placed to the uniform magnetic field (source of this field is not shown in the figure); the traping is realized for so-called "atoms seeking for low magnetic field". The only atoms with positive spin-field energy were trapped. The miminim of the field is realized at the side of the chip, close to the central part of the z-electrode with electric current.
