Development of an apparatus for the angle-resolved detection of two photons in coincidence — •Philipp Reiß, Philipp Schmidt, Benjamin Kambs, André Knie, and Arno Ehresmann — Institute of Physics, University of Kassel, Heinrich-Plett-Str.40, 34132 Kassel, Germany

The detection of photons emitted in coincidence by fragments of doubly or multiply excited molecules offers a method to study processes where no ions are formed, i.e. neutral dissociation. In addition to the time-resolved detection, the possibility to perform angular correlations of the emitted photons gives rise to a more thorough investigation of the ongoing processes.

Experimental realizations of a dedicated apparatus are presented and compared in terms of solid angle coverage, optical properties, monitoring of the target pressure and applicability for the use at synchrotron facilities.
