Some pictures of the beam on the first days of commissioning

Some images of the beam on the fluorescent dummy grating inside the monochromator

Figure 1 - An image taken at a very grazing incidence angle

Figure 2 - An image taken at large incidence angle

The beam on the fluorescent screen downstream the gratings

Figure 3 - The central spot is the 0 order of diffraction of the low-energy grating, while the elongated spots above and below are the 1st positive and negative diffraction orders.
