Abstract
The Wavelength-shifting Optical Module (WOM) is a novel photosensor concept developed in the context of the IceCube-Gen2 neutrino telescope, a next generation multi-km$^3$ neutrino telescope at the South Pole. It provides a large photosensitive area with low detector noise and improved UV sensitivity. This is achieved by combining a wavelength-shifter (WLS) coated tube with two small, low-noise PMTs. Incident UV photons are absorbed by the WLS and re-emitted isotropically. A large fraction of the light is captured in the tube by total internal reflection and guided to the small PMTs. Through its cylindrical geometry, which is well matched to the drill holes, this concept results not only in an overall improved detection efficiency, but at the same time saves production and drilling cost. In this contribution we discuss the performance characteristics of the WOM and present the current status of the prototype development.
