Thermo Scientific Electron Multiplier
Supplier: Thermo Scientific 1R7602214633

Electron multiplier™ is vacuum tube used to amplify electron beam by utilizing secondary emission, where incident electrons strike dynode surface and cause emission of multiple secondary electrons; these secondary electrons are then accelerated and focused onto subsequent dynodes, resulting in exponential increase in electron current, providing high gain while maintaining low noise levels, making it useful for detecting and measuring low-level currents in mass spectrometers.
