KWS-3 'VerySANS'focusing VSANS diffractometer operated by JCNS@MLZ
A suitable and safe access to the sample chamber with a adapter system (500 mm flange) for complex systems was designed and installed as shown following. This adapter system could be used for installation of the complex sample environments like ovens, cryo-systems, magnets… A crane has already been installed at the new wavelength chopper of KWS-2 and can be used to remove the flange and install complex (heavy) systems of the sample envi-ronment.
The maximum Q achievable in this case is about Qmax=3·10-3Å-1. As the minimum Q of a classical pinhole SANS diffractometers KWS-1 and KWS-2 is about 2·10-3Å-1, the Q-overlap between these instruments and KWS-3 was not large enough. To have more massive overlap we have built the second sample chamber at the 1.3 m sample-to-detector distances : it is adapted to the flight tubes by additional vacuum valves and is equipped with an additional sample stage. The implementation of the second sample position has allowed extending the Q-range of KWS-3 by an order of magnitude.
JULABO Refrigerated and Heating Circulators are suitable for temperature application to external systems with simultaneous operation in the bath tank. Models in different performance classes are available. The units provide high heating/cooling capacities to ensure rapid heat-up and cool-down times. With ‚Active Cooling Control' to +200 °C. ‚FP‘ models offer proportional cooling control to ensure energy-saving performance and to reduce heat generation to the environment. Convenient cleaning of dust by removable venting grid. Some models have a handle or castors to allow easy transport. All models provide a drain port on the front for conveniently draining the bath fluid. Typical applications: Temperature applications to external, closed systems, such as for example photometers, refractometers, viscometers, etc. For simultaneous application to small objects in the circulator bath.
