From Wikipedia,

MCP-RHEED is a
RHEED system in which an
electron beam is amplified by
a
micro-channel plate (MCP).
This system consists of an
electron gun and an MCP
equipped with a
fluorescent screen opposite to
the electron gun. Because of the
amplification, the intensity of
the electron beam can be decreased
by several orders of magnitude and
the damage to the samples is
diminished. This method is used to
observe the growth of
insulator crystals such as
organic films and
alkali halide films, which are
easily damaged by electron beams.
