Abstract:
An acceleration and scanning integrated structure of fully impervious high vacuum electron beam belongs to the fields of radiation processing technology. It includes accelerating tube, drift tube, scanning electromagnet and scanning box equipped with ion pump, the scanning electromagnet is mounted on top of the scanning box and is connected with the drift tube by the ring flange two, and the top end of the drift tube is connected with the accelerating tube by the ring flange one. It characterized in that the accelerating tube and the scanning box are located and fixed by bracket, the ring flange two and the ring flange one are connected with each other by welding mode with featheredge flange, the accelerating tube adopts the standing wave acceleration structure equipped with exhaust orifice. Compared with current technology, the invention improves the stability and tightness of the accelerator and makes whole volume smaller; it can discharge air in high-temperature discharging furnace directly and leave out the endless vacuum exhaust cause of accelerating tube. It possesses engineering practicability.
