Using of transparent diffraction lattice for fast z pinch plasma spectroscopy

A possibility of applying transparent diffraction of a lattice of W (∼1 μm period) for z pinch plasma spectroscopy is demonstrated. Explosion of 20 μm diameter thin wires of Al, Cu, Pd, W under 200 kA currents is investigated in ∼100 ns duration pulse. The distance from the source to the lattice is 318 mm, the distance from the source to the recording plame is 525 mm. Spectral resolution is ≅2.6 A. The limiting spectral resolution linked with uniquely small source dimensions is realized within the range of λ≥65 A. W lattices are less expensive and more transparent than lattices of Au
