Resumo
The neutron powder diffractometer recently installed at the IPEN-CNEN/SP IEA-R1
research reactor is equipped with a position sensitive detector (PSD). The PSD spans
20° of a diffraction pattern with a quite good resolution and an extended powder
diffraction pattern can be obtained in 20° segments in a 2θ interval ranging from 5 to
125°. A focusing Si monochromator and a rotating-oscillating collimator (ROC) were
also installed in the new instrument. At a take-off angle of 84°, the following
reflections/wavelengths(Å) can be easily attained with the new monochromator:
533/1.111, 511/1.399, 331/1.667 and 311/2.191. The ROC, installed at the entrance to
the detector shield, eliminates parasitic scattering from furnace or cryorefrigerator heat
shields and makes the PSD less sensitive to ambient background. Details of the
construction of the new instrument, as well as several neutron powder patterns, obtained
with different compounds, will be presented in order to give an idea of the quality of the
new instrument. Use of the IPEN-CNEN/SP PSD neutron diffractometer is open to the
scientific and technological communities from Brazil and other Latin-American
countries
