  Incom Inc. Large Area Picosecond Photodetector (LAPPD) 38 has been tested at
Jefferson Lab to identify single-photoelectron signals to assess the potential
of this type of device for future applications in Cherenkov light detection.
Single-photoelectron signals were clearly detected if a tight collimation of
photons impinging on the photocathode was used compared to the pixelation of
the charge collection signal board.
