1D Silicon strip based fast detector（Model：MYTHEN2 R 1D；Made in Switzerland）
The MYTHEN2 R 1D fits 640 strips into an extremely compact housing and provides surprisingly affordable access to DECTRIS’ HPC technology. The combination of 4 mm strip length and 320 μm sensor thickness allows for fast and accurate measurements with Ti radiation in a laboratory X-ray instrument thanks to MYTHEN2’s excellent signal-to-noise ratio. With 8 mm strip length und 450 µm sensor thickness, the MYTHEN2 is an ideal match for Cu sources, but can also be applied at other X-ray energies.
HPC technology packed in a symmetric design of the MYTHEN2 R 1D, its media-free operation and CE-certificate make it the perfect choice for portable diffractometers, robots for stress measurements, XRD benchtop systems and wavelength dispersive X-ray fluorescence instruments.
Graphite monochromator
Improve the ratio between diffraction peak and background.
Improve the identification ability of trace phase.
