Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate 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.
