Abstract
A cathode arc source apparatus for depositing a coating on a substrate is provided with a monitor for monitoring the cathode arc source. The monitor is useful for monitoring position of an arc spot on the target, plasma emission by the source, or current through or potential difference at a secondary anode. A controller can take actions such as shutting down the source, varying the power or restriking the arc in response to output from the monitor.
