ABSTRACT:
A current detector (130) is connected between the negative output terminal (-) of a high voltage DC power source (9) and the ground; the current detector (130) comprises a core (12) which is electrostatically shielded by a grounded conductive cover (15), a coil (11) wound around the core (12) and connected in series between the negative output terminal (-) and an electrode (4b) of a gas laser (1), and a Hall device (13) which is magnetically coupled to the core (12) and sends its output signal to a control signal input terminal (91) of the high voltage DC power source (9) so as to control high voltage output power of the latter.
