MCP-detectors. Z-stack
The detector with three open input MCPs with a metal anode (Z-stack) is destined for detecting ultra-weak signals resulting from spatially distributed fluxes of photons or particles. It is widely applied for scientific investigations.
The singularity of Z-stack MCP produced by “Baspik” is that it has spaces between microchannel plates (having separate supplies) and it makes it possible to obtain the gain of 1×109 in contrast to other similar assemblies which do not have spacеs between the plates and have the gain of 1×108.

The available modifications of MCPs are:
With an anode, without an anode, with a phosphor screen, and an assembly with MCP of any desirable diameter.
