Key Features
  • Low spurious noise
  • Secondary emission multiplication
  • Available with S-1, S-11, or S-20 photocathodes
  • High resolution scanning

Typical Operation

ModePlate VGm (µmhos)Rp (Ω)µPlate mA
S-1 Photocathode Dark Current————3e-9 mA
S-11/S-20 Photocathode Dark Current————1e-11 mA

Application Notes

Fundamental noise is divided into dark current fluctuation, signal current fluctuation, and multiplier secondary emission noise. Dissector noise varies as the square root of the scan speed.
