Contoh anode

• This part was attached to a stepped-down anode of smaller radius.

• An aluminium foil of thickness 15 m was installed 20 cm downstream from the anode plane to separate the gas-filled region from the propagation zone.

• The other end of the anode holder is connected to the positive plate of the capacitor bank through an atmospheric air spark gap.

• Only a slight asymmetry exists between anode side and cathode side.

• The flow then exits the collimator shock and a jet is launched into the region above the anode plate.

• Distribution of the electron density becomes strongly nonuniform from the cathode to anode along the gap length.

• This figure shows the beam divergence angle along the anode radius.

• While the new electron subsequently starts to accelerate toward the anode, it leaves behind the ion which moves relatively slowly toward the cathode.

• The electric field is decreased in the channel, and it is enhanced near the anode.

• The total magnetic field pressure at the anode edge of the constriction is higher than at the cathode edge.

• In the limiting case, this barrier coincides in height with the potential barrier for the electrons going away toward the anode.

• Since cathode spots are sources of intense electron emission, their operation is governed by the closing of the electron current onto the anode.

• They have a finite and negative density gradient, and extend from the cathode to the anode.

• As this takes place, the current of the electrons arriving at the anode decreases by the value of the emission current.

• This design uses a long hollow anode of dimensions 300 80 40 mm.
