18. In our experiments with atom chips, the microstructures creating the potentials manipulating the atoms are directly fabricated into the reflecting gold surface used as the mirror.
19. This simple type of U-MOT is typically used as an intermediate experimental stage because it can be aligned to surface patterns by construction and it allows a simple compression of the atomic cloud as it is lowered towards the surface by increasing the homogenous bias field.
20. To produce homogenous fields of this strength, currents of a few amperes in Helmholtz coils outside of the vacuum chamber are sufficient. These coils can even be replaced by integrating a current sheet into the ceramics block.
