 The IPD3000, Imaging Plate Diffractometer, is
designed for a complete diffractometric analysis without the
need of any motor nor any electronic detector. The measurement
is obtained by means of imaging plates (they can be used
thousands of times!), on which the diffracted rays are
revealed thanks to phosphors. A single complete
diffractogram can be realised in few minutes!
Imaging
Plates are nearly ideal photon detectors that give you highest
quality digital images. They replace the old films and can be
reused thousands of time.
The
collected images can be read by the program MAUD. An
high dynamic range and a great sensitivity of the imaging
plates ensure resolution and quality of the spectra!
The
Imaging Plate is a flexible image sensor in which bunches of
very small crystals (grain size: about 5 µm) of
photo-stimulable phosphor of barium fluorobromide containing a
trace amount of bivalent europium as a luminescence center,
formulated as BaFBr:
Eu2+,
are uniformly coated on a polyester support film.
Exposure
of samples to the Imaging Plate is performed in a manner
similar to that of photo-film. The exposed Imaging Plate is
scanned with a laser beam of red light while the plate is
being conveyed with high accuracy in a phosphor reader.
The
exposed Imaging Plate, while being conveyed, is scanned with a
focused laser beam. The PSL released upon the laser is
collected into the photomultiplier tube (PMT) through the
light collection guide and is converted to electric signals. |
