Typical Electrical Data for MCP 34-10
Microchannel Plates
MCP is a specially fabricated plate that amplifies electron signal similar to
secondary electron multiplier (SEM). Unlike SEM, MCP has several million
independent channels and each channel works as independent electron multiplier.
In other words, one can imagine MCP as an assembly of millions miniature SEMs.
MCP consists of a two-dimensional periodic array of very-small diameter glass
capillaries (channels) fused together and sliced in a thin plate. A single
incident particle (ion, electron, photon etc.) enters a channel and emits an
electron from the channel wall. Secondary electrons are accelerated by an
electric field developed by a voltage applied across the both ends of the MCP.
They travel along their parabolic trajectories until they in turn strike the
channel surface, thus producing more secondary electrons. This process is
repeated many times along the channel; as a result, this cascade process yields
a cloud of several thousand electrons, which emerge from the rear of the plate.
If two or more MCPs are operated in series, a single input event will generate a
pulse of 108 or more electrons at the output.

Typical Gain Curve
 |
| Graph shows typical Gain versus Applied Voltage dependence. It can be used for
estimations of the actual gain. Graph shown corresponds to Voltage at 1000 gain
(Un) equal to 760V. To estimate a Gain versus Applied Voltage dependence for
other Un values move line parallel to the specified Un value. |
