Channel Electron Multipliers (CEMs), often referred to as Channeltrons, are high-gain detectors designed to sense faint signals from electrons, ions, and UV photons. Widely used in mass spectrometry and surface analysis, they utilize secondary electron emission to amplify a single particle impact into a measurable electrical pulse.
Because the gain of a CEM is directly dependent on the applied bias voltage, power supply stability is critical. Voltage fluctuations can lead to unstable gain or measurement errors, while power supply ripple can degrade the signal-to-noise ratio (SNR).
Matsusada Precision offers a lineup of compact, high-reliability high-voltage power supplies optimized for CEM integration. Our modules deliver the precise voltage control and ultra-low noise performance required for sensitive analytical instruments.
