New Multi-MHz KWS-2 Detector Improves Count Rate by a Factor of 25
A dramatic improvement in performance has now been achieved with the installation of a new detector at the small-angle neutron diffractometer KWS-2 operated by JCNS at the Heinz Maier-Leibnitz Zentrum (MLZ) in Garching.The new detection system is characterized by a dead-time constant of 25ns and a count rate as high as 5MHz at 10% dead-time. Compared to the old detector, this means an improvement of factor 25. The much higher count rate shortens measurement times and thus increases the number of experiments which can be carried out in the same time period by the optimal use of the high flux of up to 2x108 neutrons cm-2 s-1 at the sample position. In addition, the detector’s excellent performance opens up new scientific opportunities to investigate the structures of small soft-matter and biological systems.
