F6492 Datasheet, PDF (1/2 Pages) Hamamatsu Corporation – LONG SCALE MICROCHANNEL PLATE

LONG SCALE
MICROCHANNEL PLATE
F6492
Very Long (Effective Area: 127 4mm)
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.

NOTE:
: Strip current is current flowing through the channel walls, which supplies
the current released from the channel walls. It is given by: Supply voltage
/ Plate resistance.
: At a vacuum of 1.3 10^-4 Pa (1 10^-6 Torr) or better.
