Patent ID: 6841936

Claim:
An electron multiplier, comprising: a cathode that emits electrons in response to receiving a particle, wherein the particle is one of a charged particle, a neutral particle, or a photon; an ordered chain of dynodes wherein each dynode receives electrons from the preceding dynode and when the energy of the incident electrons is large enough emits a larger number of electrons to be received by the next dynode in the chain, wherein the first dynode of said ordered chain of dynodes receives electrons emitted from said cathode; an anode that collects the electrons emitted by the last dynode of said ordered chain of dynodes; a biasing system that biases each dynode of said ordered chain of dynodes to a particular potential; a set of charge reservoirs, wherein each charge reservoir of said set of charge reservoirs is connected with one of said dynodes of said ordered chain of dynodes; and an isolating element placed between one of said dynodes and its corresponding charge reservoir.
