A switching system using laser induced discharge is provided which is capable of reliable switching with a simple structure, multiple switching for a number of circuits, good synchronization and no switching time delay among circuits. In the switching system for controlling conduction between electrodes of a switch by discharge between the electrodes, a laser beam is applied to one of the electrodes to make discharge from the other of the electrodes be induced by the laser beam and application of the laser beam is controlled to switch the conduction.

Switching system using laser induced discharge

A sabot separator includes a sabot separation cylinder equipped with a pair of rail electrodes extending axially and connected with a muzzle end of a barrel of a projectile accelerator. An electrical power source is connected between the rail electrodes and applies a voltage to the rail electrodes for producing a force in a direction for decelerating the accelerating sabot. When the sabot enters the sabot separation cylinder, an electric current flows through the sabot and the sabot is suddenly stopped by a braking force resulting from the flow of the electric current.
