Beam profiles

The following beam profiles measurements are taken at different distances from the collimator support, which effectively is the closest possible distance to the X-ray tube (d=0).

Due to the well known heel effect, there is a certain intensity gradient in the dimension along the tube axis.

All profiles have been measured at 40 kV/50 mA and with 150 um Al filter
