Abstract :
For the first time we have used a surveillance homemade flat field XUV spectrograph for the measurement of soft X-ray emission from the capillary discharge device CAPEX when using of an external capillary pre-pulse driver. The time-resolved XUV spectrum is presented. It was found that a very short intense spike that had been measured by a vacuum photodiode likely corresponds to a laser pulse. Modifications/assemblies of the spark gap switch the capillary, and the fast electromagnetic shutter are described as well.
