| contents | We propose a novel concept for the future modules of the DUNE Phase 2 Far Detector Photodetection System, namely the Polymer Wavelength shifter and Enhanced Reflection - PoWER. In this concept, the field cage of the LArTPC is entirely covered with polymeric wavelength shifting foils (PolyEthylene Naphthalate - PEN) to convert the liquid argon scintillation light from VUV to visible, and an Enhanced Specular Reflector (ESR) is installed on the membrane aiming to increase the number of reflections and consequently the detection probability. In addition, we use Light Detection Units (LDUs), which are a combination of standard and VUV-sensitive SiPM that can be used as an active veto for events occurring outside the field cage. We present a preliminary study using a Monte Carlo simulation, including a Light Map for photons generated inside the field cage and a demonstration of the active veto. |
