The two X-ray images (signal exposure and dark-background image) exhibiting the focal spot of the LES module as well as the detection capability of the used X-ray CCD 16 bit detector. The average dark signal is 266 ADU at the exposure of 80 sec ADU, the rms noise is 2 ADU, that is, the achieved electronic dynamic range is more than 30 000. The measured intensity gain of this module is 420.
