Alternative view of the diagnostics detailing the relative positions of the instruments
Figures are generally photos, graphs and static images that would be represented in traditional pdf publications.
Figure 2. Alternative view of the diagnostics detailing the relative positions of the instruments. In connection with the diagram illustrated in figure 1, the Thomson imaging system, the CCD equipped calibrated triple pinhole x-ray camera, the f/3 parabolic focusing optic that directs the 248 nm pulse to the Kr cluster target, the transverse von Hámos spectrometer, and the Z-axis associated with the plasma channel formation are shown. The axial von Hámos spectrograph with the associated goniometer is not illustrated.
Experimental evidence demonstrating amplification on the Kr26+ 3s→2p transition at λ 7.5 Å (~1652 eV) generated from a (Kr)n cluster medium in a self-trapped plasma channel produced with 248 nm femtosecond pulses is presented. The x-ray beam produced had a spectral width of ~3 eV and a corresponding beam diameter of ~150 µm, properties that were simultaneously determined by a two-dimensional x-ray spectral image formed with an axially placed von Hámos spectrometer and a matching Thomson image of the spatial electron density generated by the x-ray propagation.
