Abstract: A high voltage stable pulse power supply 10 which includes a first power supply 11, a first capacitor 12 connected in parallel with the first power supply, a first switch 13 mounted in parallel with the first capacitor 12. The switch 13 selectively connects the first capacitor 12 to a load 14 so that the first capacitor 12 may discharge therethrough. An anti-droop network 15 is connected in series with the first capacitor 12. The anti-droop network 15 cancels droop in the output of the first capacitor 12 as it discharges into the load 14. 
     In a specific embodiment, the anti-droop network 15 includes an inductive element 42 connected in series with the first capacitor 12 which is charged just prior to the activation of the first switch 13. The inductor 42 provides energy to compensate for the droop in the energy supplied by the first capacitor 12. In a more specific embodiment, the first switch 12 is implemented with a Crossatron switch 31 and a modulating anode electron gun 32 to minimize system control voltages. 
     The present invention achieves coherent emission in a free electron laser, for long pulses, allowing selection of single modes.

Abstract: The method of the present invention allows a complete contactless testing of electric components (4,40,41) including those having a complex wiring structure. For this a rigid set of test electrodes (20, 21) is placed close to the component's surface in a manner that each electrode is positioned next to the corresponding test contact (3) of the component. By applying defined voltages between selected electrodes, glow discharges (5, 51) are generated which are bridging the short distances between the respective terminal electrodes and surface contacts. As the glow discharges will carry electric current it is possible to test wiring defects, e.g. opens or shorts. A variety of test patterns can be applied either subsequently or simultaneously by addressing different test electrodes by means of a programmable pattern generator (13).
