changer are very similar but they differ in detail, see fig. 140. The distance of the airscatter screen
module’s edge from the sample surface is 1mm and 3mm (for standard sample holder), respectively.
For the sample changer there a two airscatter screen modules, one with 1mm and 3mm and a second
one with 0.5mm and 2mm (fig. 140). Decide which setting you need for the measurement and insert
the airscatter screen module as shown in fig. 40. This module is held magnetically.
Sample holder
The sample holder and sample changer are factory aligned so that the goniometer centre coincides
with the surface of the sample and the surface must be parallel to the line which connects the two
wing axes. The sample holder is mounted with four screws ((a), (b), (c) and (d) in fig. 41). The sample
changer is fixed with screws (a) & (b) in fig. 138 and (c) & (d) in fig. 139.
Caution!
Do not loosen these screws because the sample holder’s alignment will become lost.
Fans provide the interior of the D2 PHASER with fresh cooling air from the environment. An
overpressure is created inside the instrument which is relieved through the ventilation slots. When the
front door is opened, air flows from the inside to the outside of the housing through the front door.
Warning!
If the user intends to insert or remove a powder sample through the front door, it is
possible that the powder is blown toward his face or body. Use only solidly
compressed powders and samples which cannot be blown away from the sample
holder. In case of doubt use a mask and work coat in order to protect your respiratory
tracts and your body with cloths. In addition follow the working and safety conditions
and laws concerning hazardous substances.

Detectors
Three detectors are available for the D2 PHASER system: two types of 0D-detectors (scintillation
counter or XFlash detector) or a 1D-linear LYNXEYE detector. Each detector is optimized to best
performance and X-ray sensitivity at lowest background for maximum measurement speed.
