As nonthermal atmospheric pressure plasmas come to play an important role in diverse applications, reliable and arcing-free low-temperature plasma sources are needed urgently. In this paper, a low-temperature plasma jet device, which generated four plasma plumes simultaneously, is developed. The plasma jet device can be driven by pulsed do or kilohertz ac power supply. There is no risk of arcing. When the plasma plumes are contacted with a conductive surface, the four plasma plumes merge together and form a uniform plasma layer on the surface of conductive material with an area of about 1 cm(2). The gas temperature of the plasma plumes is close to room temperature.
