In order to get high density plasma,a combined pulsed vacuum arc source is designed and developed with four pulsed vacuum arc sources.The relationship of arc voltage and arc current is measured;The plasma in combined pulsed vacuum arc source and single pulsed vacuum arc source are measured using electrical probe.The relationship of probe saturation current (in proportion to plasma density)versus arc voltage and axial distribution of plasma are measured;The plasma velocity is estimated using time-of-flight method.The maximal plasma density in combined pulsed vacuum arc source is 8×1012 cm-3 .
