Electron Multiplier (EM) are highly sensitive vacuum detectors designed to amplify weak signals generated by incident charged particles. Utilizing secondary electron emission, they detect and measure electrons, ions, and photons (such as soft X-rays) with high precision. They are a critical component in analytical instruments, particularly mass spectrometry.
Because the gain of an electron multiplier is extremely sensitive to bias voltage, a stable power source is essential. Matsusada Precision offers a wide range of high-voltage power supplies engineered to provide the low ripple, low noise, and high stability required for optimal EM performance.
We also offer custom configurations to meet specific detector requirements and system integrations.
