The NEXT (Neutrino Experiment with a Xenon TPC) project is an international collaboration aimed at finding evidence of neutrinoless double beta decay using gaseous xenon. The current phase of the project involves the construction and operation of NEXT-100, which is designed to hold 100 kg of xenon at 15 bar and is expected to start commissioning in the fourth quarter of 2023. NEXT-HD will be a tonne scale experiment following NEXT-100 and will incorporate a symmetric design, with one cathode and two anodes. For this detector, the collaboration is considering implementing a barrel of wavelength-shifting fibers read out by silicon photomultipliers to measure the energy. In this talk, we will discuss the characteristics of this approach and provide an update on the related R&D efforts.
