STOE STADI P

DECTRIS MYTHEN 1K
The DECTRIS MYTHEN 1K strip detector has been implemented in the STOE powder diffraction systems. It features a range of 6 to 25° in 2Θ depending on the distance between sample and detector. With its high dynamic range of > 1×10⁶ it is superior to classical X-ray detectors.

MULTI-MYTHEN 2K/3K/4K – IF ONE MYTHEN IS NOT FAST ENOUGH
Ideal for capillary measurements, all STOE furnaces and the INSITU HT2 heating and reaction chamber.

STOE’s IP-PSD

The STOE IP-PSD is an on-line system with a readout time of about 15 sec for a full range of 140°. The Imaging Plate technology allows long exposure times to give excellent counting statistics even for weak reflections. The combination of the IP-PSD with STOE´s stages, sample changer or various high- and low-temperature systems is an explicit idea of its use.

Various sample holders are available for the STOE STADI P series.

• goniometer heads for capillaries
• for Debye-Scherrer or Gandolfi mode
• sample holders and sample changers for Transmission and Bragg-Brentano geometry
• a 10fold capillary changer
• the X/Y stage for well plates in transmission mode
• multi purpose sample stage

With its family of capillary furnaces STOE provides one of the most precise and temperature stable high temperature attachments for the STADI P series and for synchrotron facilities.

Temperature ranges are from:

• 0.65.1 room temperature to 950°C
• 0.65.3 room temperature to 1500°C
• 0.65.LT from – 50°C to 950°C

• Continuous sample spinning leading to effective particle randomization
• Well-defined sample position yielding reasonable lattice constants
• Fully integrated PC-based data collection
• Quick exchange against other sample stages and easy alignment
• Supporting all capillary diameters between 0.2 and 1 mm
• Easily adaptable for transmission samples
• Excellent diagrams obtainable from very small sample amounts

The new STOE INSITU HT2 high temperature reaction chamber has been designed to study solid state and solid state – gas reactions in capillaries in a temperature range between RT and 1600˚C on a vertically mounted transmission diffractometer, e.g. the STOE STADI P or STADI MP.
The high temperature chamber consists of a cylindrical double walled, water cooled body with an entrance collimator for the primary beam and an exit window with 90° opening for the diffracted X-rays (covered with Kapton® foil). The heating element consists of a coiled graphite
rod, which is clamped between the lid and base plate and contacted by a thermocouple
directly. To reduce effects of preferred orientation the sample can be oscillated by a motor.
The STOE IN SITU HT2 is fully computer-controlled in the newest WinXPow software version.
