Abstract
Components of scientific analytical equipment. More particularly, ion detectors of the type which incorporate electron multipliers and modifications thereto for extending the operational lifetime or otherwise improving performance. The ion detector may be embodied in the form of a particle detector having one or more electron emissive surfaces and/or an electron collector surface therein, the particle detector being configured such that in operation the environment about the electron emissive surface(s) and/or the electron collector surface is/are different to the environment immediately external to the detector.
Claims10
An electron multiplier comprising:
- one or more dynodes, each dynode having an electron emissive surface, a rear surface facing away from the electron emissive surface, and an edge;
- and
- an enclosure or a partial enclosure thereabout configured to facilitate establishing and/or maintaining a difference in an environment about the one or more dynodes and an environment immediately external to the enclosure or the partial enclosure, wherein the enclosure or the partial enclosure contacts at least one of the one or more dynodes on the rear face or on the edge thereof.
