CIRCULAR MCP AND ASSEMBLY SERIES

Hamamatsu Photonics 

OPERATING PRINCIPLE

As shown in the figure, when a voltage VD is applied across

the input-side and output-side electrodes of the MCP, a po-

tential 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 second-

ary electrons are accelerated by the potential gradient and

travel along a parabolic path determined by the initial veloc-

ity. 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 large multiplication of

the incident electron.
