A kind of fast shutter for Z pinch diagnosis device

A kind of fast shutter for protecting the diagnosis devices inZ pinch experiments is introduced in this paper. The shutter is composed of a pulling rod, a magnetic core, and a solenoid. Different from the traditionalcoils which were used at the voltage of 220 V, the solenoid we used must endure the high voltage of 5 –10 kV and the deformation which maybe caused by the 5–10 T intense magnetic field. A creative configuration for the solenoid is developed including the winding guide, insulating sleeve, and stainless-steel sleeve. The experimental results show that the configuration of the solenoid is effective . The velocity of the valve is nearly 19 m/s and the time jitter of the shutdown is within 75μs.
