Description
The Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose
experiment designed to determine the neutrino mass ordering and precisely measure
neutrino oscillation parameters. JUNO is the world's largest liquid scintillator detector
instrumented with 17,612 20-inch photomultiplier tubes (PMTs). It is critical to develop
an accurate optical model for the PMTs within their working media in order to describe
the photon detection efficiency (PDE) at any incident angle and photon wavelength.
This poster reports in detail how a combination of simulation and measurements were
used to establish the JUNO PMT Optical model. The model relates the PDE to the
underlying optical processes using a transfer-matrix method (TMM) thin film
calculation that depends on thicknesses and complex refractive indices of the
photocathode and anti-reflective coatings of the PMTs.
