Development of a ramp-up photodetector for underwater laser scanner

We developed the MCP-PMT(Microchannel plate photomultiplier tube) with RAPU(Ramp up power supply unit) for the underwater laser scanner. The gain of the MCP-PMT can be changed from 1x10<sup>3</sup> to 1x10<sup>6</sup> in a time span of 400 ns.
