HAMAMATSU F2813-21S, F2813-21M, F2813-21, F2813-13P, F2813-13M Datasheet
...
A microchannel plate (MCP) is a secondary electron multiplier
consisting of an array of glass capillaries (channels) fused into
the form of a thin plate. Each channel has an internal diameter
of 6 µm to 25 µm and works as an independent electron
multiplier, making possible the detection and amplification of
two-dimensional information.
In addition to previously available circular-type MCPs,
Hamamatsu has available seven types of rectangular MCPs. Of
these, three standard types include demountable assemblies
which have electrode leads and read-out devices. Using these,
it is possible to alleviate dimensional limitations encountered
when building the MCPs into instruments as compared with
circular types, greatly facilitating the effective use of these
devices. The demountable assembly can be selected as combinations of MCPs (1 to 3 stage) and a read-out device (singleanode, multi-anode or phosphor screen). Making possible the
selection of the most suitable configuration for your application,
while facilitating replacement as well.
Subject to local technical requirements and regulations, availability of products included in this promotional material may vary. Please consult with our sales office.

A This indicator shows the MCP input side and the direction of channel bias.
The F2806-01 has bias angle of opposite direction against the perpendicular line shown in the figure.
B The strip current is the current which flows along the channel wall when a voltage is supplied between the MCP input and output and is given
by Supply voltage/Plate resistance.
