Abstract
A system for detecting ions is disclosed. The system includes a detector having a plurality of dynodes arranged in an electron cascading configuration, and a power supply circuit electrically coupled to the plurality of dynodes. The plurality of dynodes include a first dynode and a second dynode. The power supply circuit is arranged to selectively adjust a potential difference between the first and second dynodes between a detection mode and a blanking mode. A method of detecting ions is also disclosed.
