MCP unit, MCP detector, and time-of-flight mass spectrometer

摘要

There is three-stage structure and structure to reach limitation caused by the channel diameter of required time resolution characteristics independent of MCP, have a MCP group, the 1st electrode, the 2nd electrode, anode, acceleration pole by a kind of MCP units, the present invention. Particularly, MCP units further include that ring accelerates between electrode and anode, accelerate electrode and anode out of space between MCP groups as s limiting structures are used to limit secondary electron of the electronics of reflection from anode in response to incident radiation.
