- High Stability: 10 ppm / 5 min stability ensures consistent performance.
- Ultra-Low Noise: Ripple noise as low as 10 mVp-p for precision imaging and detection.
- Monitoring Functions: Equipped with output voltage and current monitoring.
APPLICATIONS
- Mass Spectrometry (MS) accelerator
- Scanning Electron Microscope (SEM) accelerator
- SEM bias
- Electron beam/Ion beam
