It is the first time that no additional anode was adopted in the magnetic macroparticles filter. At the same time the auto-re-igniting system was designed for vacuum cathodic arc deposition instrument. It ignites the arc with an electronic component with high voltage and can auto distinguish weather the arc dies out or is on during the deposition via a main power supply feedback unit. The energy for igniting the arc is very less and thus can successfully prevent the film being contaminated.

设计制造的电子式真空阴极弧离子镀引弧器成功地实现了高压脉冲引弧，可以多次重复使用，所用能量较小，可以有效防止对所镀膜的污染，引弧可靠，能够自动识别电弧是否引燃，能够在熄弧后自动重新引弧，重新引弧的速度快，有效防止了熄弧引起的气压波动，使镀膜过程中气压非常稳定。
