The Efficiency of the Wavelength-shifting Optical Module (WOM) for IceCube — •John Rack-Helleis, Sebastian Böser, Anna Vocke geb. Steuer, Lutz Köpke, Max Bubeck, Florian Thomas, and Lucas Sebastian Binn for the IceCube collaboration — JGU Mainz

The Wavelength-shifting Optical Module is a novel photosensor developed for the IceCube neutrino telescope at the South Pole. It combines the technology of light guiding and wavelengthshifting to achieve a large detection area, high sensitivity in the UV range as well as an improved signal-to-noise ratio. The WOM will be deployed and tested in the IceCube Upgrade, scheduled for 2021. Recent results on the modules photon propagation efficiency and its main contributors will be presented. The state of the understanding of theoretical and experimental efficiency is shown.
