Abstract

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.
