| Description: |
The photon detection system of the DUNE experiment is based on the X-ARAPUCA lighttrap. The basic elements of the X-ARAPUCA are the dichroic filters coated with wavelength shifter(para-Therphenyl), a waveshifting plate and an array of SiPMs which detects the trapped photons. Asmall scale prototype of the X-ARAPUCA has been installed in liquid argon in a dedicated facilityat INFN-Napoli and exposed to alpha particles from a source. In order to test the stability ofthe overall device response the X-ARAPUCA was kept for 10 days in continuously purified liquidargon. The performed tests allowed for a preliminary estimation of the X-ARAPUCA absolute photondetection efficiency. |
