2 Overview
2.1 Description of the Instrument
The DHS 1100 Domed Hot Stage is a heating at-
tachment for four-circle X-ray diffractometers. It is
designed for X-ray diffraction experiments in reflec-
tion geometry with sample temperatures from 25 °C
to 1100 °C.
The unique design of the instrument provides:
- Sample temperatures from 25 °C to 1100 °C
- High temperature uniformity across the sam-
ple
- Easy sample mounting
- Compact design, low weight and high flexibil-
ity
- Versatile applications
The special, dome-shaped X-ray window of the
DHS 1100 sample stage combines two important
properties: gas-tight enclosure of the sample and X-
ray transparency over the complete half space
above the sample. Because of the gas tightness,
samples can be investigated in vacuum or inert gas
to avoid oxidation or other chemical reactions of the
sample at high temperatures.
Due to the design of dome, heater and sample fix-
ing, very low angles of incidence can be reached
and the following types of X-ray measurements can
be carried out:
- pole figures
- grazing incidence diffraction
- grazing incidence in-plane diffraction
Cooling of the dome and the housing of the
DHS 1100 attachment is achieved by using com-
pressed-air. The cooling air supply is controlled with
the CCU 100 Combined Control Unit. The CCU 100
monitors if sufficient cooling air is available and au-
tomatically turns on the cooling air if the heater tem-
perature exceeds 200 °C.
Below 200 °C heater temperature, the instrument
can be run without dome and without cooling air.
The main applications for the DHS 1100 are to in-
vestigate the temperature dependence of
- crystalline textures
- crystal stress and strain
- temperature-induced phase transitions
- structural properties of thin films
To ensure reliable operation of the DHS 1100, the
instrument must be operated with:
• 135000 CCU 100 Combined Control Unit
In order to avoid contamination of the DHS 1100 by
the cooling air, Anton Paar GmbH provides an
air
service unit
with pressure regulator and air filters
as an accessory:
• 6931 AIR SERVICE UNIT
If vacuum operation is required, Anton Paar GmbH
offers:
• 58974 Standard Vacuum Equipment
If a PEEK dome is required instead of the standard
graphite dome, an additional cooling nozzle is nec-
essary as the PEEK dome has to be cooled also on
the top side of the dome. Two cooling nozzles are
optionally available as an accessory:
• 135038 DOME COOLING NOZZLE DHS 1100
(600 °C)
• 159567 HT DOME COOLING NOZZLE
DHS 1100 (900°C)
