Changes of the defined parameters (a) R56peak, (b) FELpeak1, (c) σwidth and (d) R as a function of changes to the electron beam slice energy spread (blue curves), beam peak current (orange curve) and seed laser energy (green curves). Changes to parameters are normalized such that variation = [(value − nominal value)/half range] to simplify the graph. The electron beam current is varied by ±50 A for a nominal current of 550 A, energy spread is varied by ±30 keV for a nominal slice energy spread of 60 keV, and seed laser energy is varied by ±5 µJ for a nominal energy of 20 µJ. |
