Powder diffractometers
Powder diffractometer I
A complete Seifert XRD 3000 TT system with PC control and data
analysis software.
- Cu- or Mo-anode x-ray tube
- vertical theta-theta goniometer
- Anton Paar temperature attachment (-190...+450 deg C)
- secondary graphite or LiF monochromator
- NaI(Tl) scintillation detector
Powder diffractometer II
- Seifert ID 3003 x-ray generator, Cu-anode x-ray tube
- optional goniometer systems:
1. Huber 414 2-circle goniometer
2. Huber Guinier diffractometer with
a) a model 642 goniometer for flat powdered specimens, Seemann-Bohlin focusing principle,
symmetric/asymmetric transmission/back-reflection geometry, or
b) a model 653 goniometer including a model 656 texture device for solid specimens
coated with a thin film or material different from the substrate, reflection geometry under grazing
incidence of the primary x-ray beam
- Johansson-type quartz monochromator
- NaI(Tl) scintillation detector
- Laue camera, Polaroid XR-7 Land Diffraction Cassette
- PC-based motion control (Oregon Micro Systems PC48-4) and data acquisition systems
(Keithley Metrabyte CTM-10), both controlled with SPEC software
Powder diffractometer III
Huber 420/511 4-circle goniometer, reflection or transmission geometry,
various specimen holders
- Seifert ID 3003 x-ray generator, Cu-anode x-ray tube
- primary Ge monochromator
- versatile beam size control either by slits or pinhole collimators
- NaI(Tl) scintillation detector
- PC-based motion control and data acquisition systems, SPEC software
