5 Putting TTK 600 into Operation
5.1 Alignment of the Standard Sample
Holder
Proper alignment of the TTK 600 Low-Temperature
Chamber is important to get good data quality. The
surface of the sample holder must be parallel to the
axis of the X-ray beam (
Θ
-zero line) and in the cen-
ter plane of the goniometer.
An alignment block with a small slit for accurate
chamber alignment is available as an option
(mat. no. 162029)
The alignment of the TTK 600 consists of height (z)
alignment and rotation (
ω
) alignment. The actual
alignment procedure depends on the type of adapt-
er (rigid or with motorized z-stage), on the diffrac-
tometer type and on the used sample holder.

Read the related sections in the instruction manual
for your diffractometer before you start the align-
ment.
It is important that the X-ray beam height and the
detector are properly aligned before you start to
align TTK 600, because the sample chamber is
aligned relative to the X-ray beam (
Θ
-zero line).
Perform the alignment of TTK 600 at room tempera-
ture.
Alignment is best done in two steps:
1. Coarse alignment with the upper edge of the
empty sample holder.
2. Fine alignment with the alignment slit in the
alignment block.
5.1.1 Height Alignment with Rigid Adapter
The height (z-position) of the sample chamber rela-
tive to the X-ray beam can be adjusted with the
alignment equipment mounted on the base-plate of
TTK 600.
The alignment sample holder is available as an op-
tion (mat. no. 162029).
Fig. 40: Rigid Adapter
1. Slightly loosen the screws (1) which fix the
adapter to the chamber base-plate so that the
chamber can move up and down on the adapter.
2. Move the chamber up or down by means of the
adjusting screw (2).
3. When you have found the desired position,
tighten the fixing screws (1) again.
Adjusting screw:
Turn clockwise to move the chamber upwards.
Turn anti-clockwise to move the chamber down-
wards.
NOTICE
Do not perform the rotation (
ω
) alignment your-
self if you have a diffractometer with alignment
preserving sample stage fitting. For such instru-
ments the sample stage is usually pre-aligned.
Re-alignment should only be done by a service
engineer from your diffractometer manufacturer.
