The achieved energy resolution is typically ~1 eV at 10 keV depending on the crystal analyzer and the Bragg angle. The instrument is equipped with an helium chamber designed to limit the X-ray absorption by air along their source-analyzer-detector path, which is particularly important in the low energy range.
The maximum x-ray tube power is 1.5 kW but most often the highest throughput that is used is 800 W (with 20 kV, 40 mA).
