dc.description.abstractThere is a noticeable difference in the design of the stress TOF spectrometer and the constant wavelength diffractometer: the later one usually has only one detector while TOF instruments are equipped with at least two banks of detectors and sometimes full or part circle of detector banks. The one detector design of the diffractometers is due to asymmetry of the resolution of the constant wavelength diffractometer when right and left position of a detector are not equivalent but can be distinguished as “+/+” and “+/-” configurations in respect to the directions of the neutron beams. The fact of the matter is that only “+/-“configuration has the best achievable resolution and flux as predicted in the parallel beam simplified model. Thus, despite all benefits of using double detector system (especially for the in-situ diffraction experiment), there is no practical solutions found yet for the constant wavelength diffractometers. The attempt has been made to study the question of practical feasibility of the double detector system on Kowari by undertaking two major approaches. First, we studied experimentally resolution and changes in flux of the two (“+/+” and “+/-“) detector positions by repeating standard powder measurements using the same detector and slit setup. Second, the instrument characteristics in the two detector position were evaluated by modelling using McStas package for the neutron optics simulation. Interpretation and discussion of the obtained results will be presented and the practical usefulness of the double detector system will be disputed.en_AU
