Description
The single crystal hot neutron diffractometer HEiDi is operated by Forschungszentrum Jülich at the research reactor FRM II in Garching. Core of the instrument is the 4-circle diffractometer, consisting of an Eulerian cradle for the sample and the detector arm. The detector of HEiDi is a single a 3He detector tube. In classical scans, in each step the axes of the 4-circle diffractometer are moved to the desired position and then the measurement is started. A reduction of measurement time can be achieved by measuring also during movement. The necessary synchronization between the motion subsystem and the detector is being implemented. The motion subsystem is based on a Siemens S7-1500 PLC and the synchronization uses its cam track technology objects.
