0 one of the electrodes (= objects that electricity moves through) in a piece of electrical equipment. The anode is the negative electrode in a battery and the positive electrode in an electrolytic cell. -- 正极，阳极
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.
