Fig. 3From: Straightening of superconducting HERA dipoles for the any-light-particle-search experiment ALPS IISchematics of the experimental setup of ALPS II in a straight section of the HERA tunnel. The two strings of 12 straightened dipoles each are connected by a vacuum insulated bypass line for cold Helium and the magnet current, leaving sufficient space for the setup of the optics in the middle of the experiment. The Helium and the current for the magnet strings are supplied at the box closest to the DESY siteBack to article page
