An apparatus for suppression of arcs in an electron beam generator including: a first module providing an operating voltage; a second module including a coil suitable for a voltage of at least 10 kV, and at least one free-wheeling diode connected in parallel to the coil; a third module including a first circuit component configured to detect a first actual value for electric voltage, and a first signal is producible when the first actual value falls below a first threshold value, a second circuit component by which a second actual value for electric current is detectable, and a second signal is generated when the second actual value exceeds a second threshold value, a control logic, which optionally links the first and second signals and a resultant output signal is producible; a semiconductor-based switch suitable for the voltage of at least 10 kV, which is opened based on the output signal.
An apparatus for suppression of arcs in an electron beam generator, comprising the following components connected in series:
