Indicator of the incidence angle Ω
2 - Sample clamp
3 - Positioning pin
The non-spinning sample holder is designed to be easily used. The sample holder is equipped
with a positioning pin to avoid any position mistake, an incidence angle indicator to read the
incidence angle and a sample clamp to maintain the powder sample mount.
Insert the sample holder in the sample holder
mounting hole of the instrument (7), do not
use any unnecessary force. The sample
holder and the mounting hole (φ 30 mm) are
designed to avoid any mechanical clearance
resulting in irreproducible results. The pin of
the sample holder has to be inserted in the
reference hole (7.1).
The incidence angle indicator consists of two rings. One ring is fixed while the second one is
free. This allows the sample holder to rotate in order to change the incidence angle. This
second ring can be tighten to avoid changes of the incidence angle. The wa y of reading the
incidence angle indicator is described in the picture below. The longest line represents the
incidence angle equal to 0°. Each short line represents 2° of incidence angle. The medium
long lines represent 10° of incidence angle. The indicator then serves to read the total
incidence angle.
