Concept of an inverted Ring Imaging Cherenkov detector — •Maximilian Rinnagel, Otmar Biebel, Bernhard Flierl, Maximilian Herrmann, Christoph Jagfeld, Felix Klitzner, Katrin Penski, Sebastian Trost, Chrysostomos Valderanis, Fabian Vogel, and Ralf Hertenberger — LMU München

The concept of this Ring Imaging Cherenkov detector consists of a lead glass volume inside which Cherenkov light is created by traversing particles. Afterwards Cherenkov photons are converted to electrons by a CsI photocathode. The created photoelectrons enter the drift gap of a Micro Pattern Gaseous Detector. Signals on the readout strips of the detector allow for the reconstruction of the momentum of a known particle by the size of ellipses illuminated by the Cherenkov light. Simulations for the efficiency of particle yield and their respective energy have been performed for cosmic muons to investigate the feasibility of this detector design. Furthermore studies of the detector components e.g. the photon spectrum of the lead glass are presented.
