This paper reports a new generation of all-directional ion implantation and enhanced deposition industrial machines recently developed by the Southwest Institute of Physics of the nuclear industry. It has a diameter of 90 m and a height of 105 m. It is placed vertically. The extraction system consists of a molecular pump and a mechanical pump, and PL C control is achieved. The background vacuum is less than 4 × 10 -4 Pa. Gas and metal plasmas can be generated by a hot cathode amplifier and three high efficiency magnetic filtered metal plasma sources, respectively. The top of the vacuum chamber is provided with a flange port and a cooling target. The aircraft negative pressure pulse amplitude of 10 ~ 80 k V, repetition frequency of 50 ~ 500 Hz, pulse rising edge is less than 2 μs, and can be generated as needed pulse train. Generally, the plasma density is 10 8 ~ 10 10 cm -3, and the film deposition rate is 0.1 ~ 0.5 nm / s. The article also reported some experimental results
