Abstract
Line-shaped plasmas produced by laser irradiating solid targets in line focus are of a large aspect ratio. Such plasmas are useful for x-ray laser demonstration and amplification and absorption spectroscopy as well. Soft x rays emitted from line-shaped plasmas can provide accurate information of such plasmas. Here, we report the studies of x-ray radiation transfer and spatial uniformity of line-shaped plasmas with a pinhole transmission grating spectrometer (PTGS), with a spectral resolution of 2-5 Å and a spatial resolution of 60 µm, and a soft-x-ray streak camera, with a time resolution of 30 ps.
