ArcKill™ is an optional plug-in module that fits inside the Optima® master unit. It is designed to extinguish arcs very quickly and deliver minimal energy into the arc, thereby limiting the arc's damage potential.
Instead of using a primary current threshold as the arc detection mechanism, ArcKill™ uses the output waveforms. It can detect an arc in 50 nsec (at least 40 times faster than with the standard arc detection scheme). ArcKill™ delivers 400 times less arc energy than the previous industry standard, and 40 times less than the standard Optima® OPT-200.
ArcKill™ can handle up to 5,000 arcs per second. If for some reason ArcKill™ fails to detect an arc, the energy delivered to the arc will be limited to the output energy of the OPT-200, still 10 times lower than the previous industry standard. In contrast to ENI arc suppression technology, when other arc suppression enhancement modules fail to detect an arc they actually add arc energy to the output of the associated power supply.
ArcKill™ has been demonstrated to be highly effective in very arc-sensitive processes such as magnetic thin film sputtering, and even in difficult processes such as the DC sputtering of Al2O3. ArcKill™ is currently available for output power levels up to 60kW.
