wherein the intermediate electrode is formed on a supporting member provided on a side of the target opposite to the electron
source,
wherein the intermediate electrode is connected to a power source and is applied with a potential greater than that applied
to the anode electrode, and
wherein the anode electrode is connected through a resistor to the intermediate electrode.
