Three quarter cross section through the science chamber. The science chamber is manufactured from a single piece of titanium alloy (Ti6Al4V) and has an octagonal shape with an inner diameter of 6.5 cm. The top part, which opposes the atom chip, provides five additional viewports. In total, eleven viewports around the chamber allow for optical access. The atom chip sits in the center of the chamber and the whole setup is surrounded by four pairs of copper-wire coils. All cables and fibers are omitted for clarity and the y-axis points along gravity
