Any light particle search II - Technical Design Report

This document constitutes an excerpt of the Technical Design Report for the second stage of the Any Light Particle Search (ALPS-II) at DESY as submitted to the DESY PRC in August 2012 and reviewed in November 2012. ALPS-II is a Light Shining through a Wall experiment which searches for photon oscillations into weakly interacting sub-eV particles. These are often predicted by extensions of the Standard Model and motivated by astrophysical phenomena. The first phases of the ALPS-II project were approved by the DESY management on 21 February, 2013.
