After breakdown of the switch, the storage inductor was switched to the vacuum electron diode.
Figure 3 shows the cross-sectional view of the adding section, which consists of two induction cells and a diode.
Magnetically insulated ion diode with a gas-breakdown plasma anode.
Owing to strong absorption of the crystal for the diode frequency, 90% of the pump power was absorbed at a depth of 1 mm.
By optimizing the extraction diode geometry and reducing the beam current, the spherical aberration was later improved and therefore the beam profile became more uniform.
One complication is the very high sensitivity of the diodes, which are essentially 100% quantum efficient.
The dose sampling rate of the diode detector was chosen to be at least 20 because of the unstable nature of the electron beam.
The electron beam was produced by discharge of the secondary capacitor on a fieldemission diode.
