Ferranti GRD7 Guard Ring Diode

Designed as a laboratory device with which perform demontrations of the Richardson’s Law, the Child-Langmuir Three-halves Power Law, and Hull's Law (Basic Magnetron Effect, can be demonstrated by surrounding the diode with a solenoid to produce a magnetic field parallel to the electrode axis).
Also suitable for use as a high stability saturated diode.
