<p><strong>Figure 2.</strong> Alternative view of the diagnostics detailing the relative positions of the instruments. In connection with the diagram illustrated in figure <a href="http://iopscience.iop.org/0953-4075/46/15/155601/article#jpb468344f1" target="_blank">1</a>, the Thomson imaging system, the CCD equipped calibrated triple pinhole x-ray camera, the <em>f</em>/3 parabolic focusing optic that directs the 248 nm pulse to the Kr cluster target, the transverse von Hámos spectrometer, and the <em>Z</em>-axis associated with the plasma channel formation are shown. The axial von Hámos spectrograph with the associated goniometer is not illustrated.</p> <p><strong>Abstract</strong></p> <p>Experimental evidence demonstrating amplification on the Kr<sup>26+</sup> 3s→2p transition at λ 7.5 Å (~1652 eV) generated from a (Kr)<em><sub>n</sub></em> 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.</p>
