Datasheet F2813-21S, F2813-21M, F2813-21, F2813-13P, F2813-13M Datasheet (HAMAMATSU)

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.

ORDERING INFORMATION (Type No. Designation)

WIRING EXAMPLES

■ SPECIAL MCPs AND ASSEMBLIES

• Hamamatsu Photonics can receive orders for special MCPs and assemblies not included in the standard product line.

• For multianode types, specify the desired anode pattern.

• Assemblies mounted on custom vacuum flanges or substrates are also available.

OPERATING PRINCIPLE

As shown in the figure, when a voltage VD is supplied across the
input-side and output-side electrodes of the MCP, a potential
gradient is built up along the channel direction. If an incident
electron strikes an inner wall on the input side, a number of
secondary electrons are emitted. These secondary electrons
are accelerated by the potential gradient and travel along a
parabolic path determined by the initial velocity. They then
collide with the opposing wall surface, causing secondary
electrons to be emitted again. In this manner, the electrons
collide repeatedly within the channel as they pass towards the
output side. The result is a logarithmic multiplication of the
electron current appearing at the output.

■ PRECAUTIONS FOR USE

• Don’t touch the MCP and assembly parts with bare hands.

• Always handle the MCP in an area that is maintained at the same level of cleanliness as a clean room since dust and

humidity may adversely affect MCP characteristics.

• The MCP should be kept in vacuum or nitrogen atmosphere when storing it after delivery.

• If excessive outgas from the MCP occurs, perform vacuum-baking of the MCP at +350°C maximum in an evacuating

system. Alternatively, electron bombarding of the MCP is effective. (Please consult our sales office for details.)

• The MCP and MCP assemblies must be operated in a vacuum below 1.3 × 10

-3

Pa (1 × 10-5 Torr). However, phosphor

output MCP assemblies and other assemblies using a three-stage MCP should be operated in a vacuum below

1.3 × 10

-4

Pa (1 × 10-6 Torr).
