(Fig. 6-1: 2) delivered with DHS 1100.
Mounting with Anti-Scatter Slit
The Anti-Scatter slit has springs on either side
(Fig. 15: 3) with which it is fixed in the segments (4)
around the heater as shown in Fig. 15: . Grooves in
the PSC (Fig. 6-1: 1) position the ASS on the PSC.
Fig. 16: Mounting of the ASS
Fig. 17: Screws underneath the segment
1. Put the PSC in the middle of the sample cup.
2. Insert one side of the ASS into the opening in
one of the segments and connect the PSC and
the ASS as shown in s. Be careful not to scratch
the heating plate with the ASS.
3. Press the spring on the other side inwards and
insert it into the ring. Slightly move the PSC so
that the ASS rests in both grooves and fully
push down the ASS onto the PSC.
When you mount the ASS as shown in Fig. 16: ,
mind the screw underneath the segment
(marked in Fig. 17: ) and position the ASS
beside the screw. Otherwise you cannot push it
down completely.
4. Secure the PSC with min. two springs.
The PSC increases the temperature deviation be-
tween the sample surface (probed with the X-ray
beam) and the value displayed on the CCU 100. We
recommend to carry out a temperature validation
measurement to determine this deviation before
starting with the actual experiments.
6.2.3 Sample Temperature
Be aware that, depending on the sample thickness
and the thermal conductivity of the sample, the tem-
perature of the heating plate will be different from
the temperature of the sample surface.
The temperature gradients across the sample are
much smaller in inert gas atmosphere than in vacu-
um.
6.3 Mounting and Removing the Dome
NOTICE
Risk of damage
We recommend to use the two segments shown
in Fig. 7-3. In case you cannot push down the
ASS completely due to the screws, the other
segments are also possible however make sure,
that the spring does not touch the heater (1) as a
short circuit may occur otherwise.

NOTICE
Risk of damage
The springs of the ASS loose their elastic force
at temperatures above ~ 750 °C. We recom-
mend to use the ASS only at temperatures
below this value.
CAUTION
• Always check the dome before you mount it.
In case of a defect do not mount it.
• The graphite dome is a fragile item, handle it
with particular care.
• Always lift the dome by the fixing ring, do not
touch the graphite dome.
• Always make sure that all parts of the instru-
ment are cooler than 50 °C before you start to
remove the dome.
