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 February 21st, 2013.
