First picture shows the overall vew of the chamber, which is surraunded by three pairs of Helmhotz coils - one for each direction. The coils compersate for the Earth's magnetic field inside the chamber to about 1 mGauss with similar inhomogenuities along the electron trajectories. You can also see water lines and water filters that are needed to run the diffusion pump, the Ar ion laser and dye circulators of the dye lasers.
Second picture gives a closer look of the chamber.
A number of wires are attached to the chamber via vacuum feedthroughs in the flanges.
