Abstract:
1. Apparatus for laser-triggered driving of a soft x-ray laser, the apparatus containing a generator ( 7 ), a spark gap ( 3 ) a capillary ( 4 ), an energy storing capacitor ( 1 ) having capacitor faces ( 1 a , 1 b ) and a laser source ( 16 ) being arranged off-axis with the capillary ( 4 ) and emitting laser radiation into the spark gap ( 3 ), characterized in that the spark gap ( 3 ) is placed in a fluid environment and the apparatus contains a current transformer ( 12 ) for transforming the current supplied by the charged energy storage capacitor ( 1 ) to a given measurement range, a triggering circuit ( 14 ) for measuring the transformed current and generating a triggering signal for the laser source ( 16 ) inducing excess charged particles in the spark gap ( 3 ), a signal delaying unit ( 15 ) for delaying the starting signal emitted by the triggering circuit ( 14 ) and an optical system ( 18 ) for focusing the laser pulses of the laser source ( 16 ) to at least one point of the spark gap ( 3 ).
