This new long-scale MCP allows for continuous detection
of wide range position information without dead space cor-
rection. This new configuration promises reliable measure-
ment, and is well suited for double-focusing mass spec-
trometers. Assembled configurations are also available
upon request.

PRECAUTIONS FOR USE
Avoid touching the MCP or MCP assembly with
bare hands.
Handle the MCP only in a clean room since dust
and humidity may adversely affect MCP
characteristics.
The MCP should be operated in vacuum below
1.33 10
-4
Pa (1 10
-6
torr).
The MCP should be kept in vacuum or dry nitrogen
gas atmosphere during long periods of storage.
When outgassing from the MCP occurs, baking the
MCP at 350 C maximum in a vacuum system is
recommended. In addition electron bombarding
may be effective.
