PMT and MCP are core components for detecting ultra-weak single-photon and single-ion signals. They are applied in wafer defect inspection, secondary ion mass spectrometry (SIMS), environmental analyzers, nuclear radiation monitoring, fluorescence spectroscopy and biomedical testing, amplifying faint signals by 10⁶ to 10⁸ times for ultra-high sensitivity detection.
1. Supply graded negative high voltage for PMT photocathode, dynodes and anode to build accelerating electric fields for photoelectron multiplication;
2. Provide bipolar high voltage for MCP to multiply charged particles inside microchannels;
3. Ultra-low ripple design eliminates high-voltage noise interference and maintains excellent signal-to-noise ratio.
Voltage range -5kV~-50kV, 8~16 channels synchronous graded output, stability ≤±0.005%/h, ripple ≤10mVpp, soft start and overcurrent protection prevent detector surge damage.
Precision graded high voltage creates accelerating electric fields inside PMT/MCP. Incident photons or ions trigger photoelectron avalanche multiplication, amplifying ultra-faint signals up to 10⁶~10⁸ times to support high-end analytical instruments with single-photon detection capability.
