A recent development also allows measurement in ‘normal beam’ (lifting-counter) geometry (i.e. ...

D19 shares the H11 thermal beam tube with the two powder diffractometers D2B and D20. Important features of D19 are: - D19 “sees” the neutrons first (from part of the H11 beam tube: diameter 20 cm at the ...

The supermirror-coated guide provides the highest white beam flux at the sample position in ...

r features are visible in the data. The features are clearly dependent on the polarization of the beam, in particular those features labeled 'correlated roughness', showing that they have a magnetic c

the resolution you need. Set he height of the beam (s3h) to be 5mm less than the sample height H. You may have to set it twice. With the sample out of the beam set the conditions for the choosen angles (opening ... into the beam. Switch on the power supply found under the detector tank (black switch) and the slit should oscillate up and down. This ...

primary white beam is reflected by a focussing monochromator made of 9 highly oriented pyrolytic graphite (HOPG) providing an important flux at the sample. The monochromator housing has two beam holes at take-off ... 85° and 115°, corresponding to 4.5 Å and 5.6 Å beams with HOPG and incorporates the slit systems and cooled Beryllium filter in a way ...
