Experimental observations of seed growth and accompanying pedestal contamination in a self-seeded, soft x-ray free-electron laser

Measurements of the soft x-ray, self-seeding spectrum at the Linac Coherent Light Source (LCLS) free-electron laser generally display a pedestal-like distribution around the central seeded wavelength. This pedestal limits the spectral purity and can negatively affect some user applications not emplo...
