Simulations show the 19-PMT, 4-inch hDOM for TRIDENT can match or exceed the 31-PMT, 3-inch design on neutrino efficiency and reconstruction, provided the 4-inch PMTs achieve comparable quantum efficiency and timing.

abstract
The 3-inch Hamamatsu R14374-02 photomultiplier tube is an improved version of the R12199-02 model and its successor in the construction of the KM3NeT neutrino telescope. A total of 1000 photomultipliers were analysed to assess their dark count rate, transit time spread, and spurious pulses. A subset of 200 photomultipliers were further evaluated to determine their quantum efficiency which is an essential parameter for Monte Carlo simulations of the detector response. The measurements show that R14374-02 model has better quantum efficiency homogeneity over the photocatode and better time properties than the R12199-02.

A Cost Effective Optimization of the hybrid-DOM Design for TRIDENT
Simulations show the 19-PMT, 4-inch hDOM for TRIDENT can match or exceed the 31-PMT, 3-inch design on neutrino efficiency and reconstruction, provided the 4-inch PMTs achieve comparable quantum efficiency and timing.
