Experimental tests with MISANS (Modulated Intensity Small Angle Neutron Scattering) at IPNS (Intense Pulsed Neutron Source)

In this paper we describe the latest tests of the MISANS spectrometer at the IPNS in Argonne, USA. At this stage the time resolution and more importantly the contrast of the modulation at the detector is very low, nevertheless it was possible to perform a MISANS-measurement and test some features typical for a pulsed neutron source. The MISANS technique has a huge potential to improve its contrast and resolution towards a high resolution spin echo spectrometer.
