(DECPOL). This makes it possible to monitor separately the polarisations of the incident and scattered beams, in 3 dimensions.

front of the neutron guide crossing the "casemate" wall, and after the beam monitor and attenuator, there is a remotely controlled beam-defining aperture. The control box for this unit is in the instrument ... the mirror. Their direction can be made co-axial to the incoming neutron beam, thus faciltitating the setup of the sample in the beam. 7. ...

imaging, that can see inside materials and examine processes therein. White beam imaging is based on the attenuation of the neutron beam, due to absorption or scattering, through an object. Tomography is performed

bar [ more ]. Polarimetric NSE demonstrated On a standard spin-echo spectrometer, the fact that the beam is essentially depolarised right before the sample is unimportant in systems where there is no sp ... functions which are useful for carrying out neutron scattering experiments, especially with polarised beams.

direct beam measurment. There are several subroutines available. The simplest one just divides the 2D image by a direct beam spectrum by interpolating the direct beam wavelengths to the reflected beam measurement: ... is the reflected beam measurement, 370340 is the direct beam run number and 370341 is the background measurment. slitwit slitwit is ...
