Analysis of EUV radiaton from plasmas with low-Z elements and application to pulsed power experiments

Summary form only given. The goal of this work is to develop theoretical support for advanced EUV diagnostics for magnetic insulation transmission line (MITL) study at SNL and for Z-pinch plasma study in general. EUV spectra of carbon and oxygen ions have been generated by a laser plasma source at the Z-pinch and laser-plasma X-ray/EUV facility at UNR. This source was designed for testing and calibration of the new X-ray/EUV devices. Polyethylene and mylar slabs attached to the computer-controlled 2D translation stage were used as targets. EUV spectra were collected by a spectrograph with a sliced multilayer grating which can cover a broad spectral region of 130-280 Aring. To increase sensitivity of the spectrograph and to add spatial resolution, glass capillary optics was employed. Non-LTE kinetic models developed for low-Z elements have been tested and used to identify the spectra and to provide plasma parameters. Application of these models and synthetic spectra to the existing and future MITL experiments on the 20 MA Z accelerator at SNL is discussed
