For further efforts in saving energy in lighting installations, intelligent sensors are indispensable. Despite the fact such sensors are available precise and reproducible measurements of the coverage areas are missing. Therefore, METAS decided in 2020 to install the world's first manufacturer-independent fully automated measurement system to test passive infrared motion and presence sensors according to the recently published standard IEC 63180:2020. The test facility allows reproducible measurements of radial and tangential movements by moving different scaled and heated dummies on linear tracks. Furthermore, the presence detection can be measured with an automated robot arm. The test results are provided in a digital test report and the data is available in a machine-readable format to be further processed in designing and planning softwares.

Insight Into

One of the major materials problems encountered in the development of fast breeder reactors for commercial power generation is the phenomenon of swelling in core structural components and fuel cladding. This volume expansion, which is due to the retention of lattice vacancies by agglomeration into large polyhedral clusters (voids), may amount to ten percent or greater at goal fluences in some austenitic stainless steels. From a design standpoint, this is an undesirable situation, and it is necessary to obtain experimental confirmation that such excessive volume expansion will not occur in materials selected for core applications in the Fast Flux Test Facility, the prototypic LMFBR now under construction at the Hanford Engineering Development Laboratory (HEDL). The HEDL JEM-1000 1 MeV electron microscope is being used to provide an insight into trends of radiation damage accumulation in stainless steels, since it is possible to produce atom displacements at an accelerated rate with 1 MeV electrons, while the specimen is under continuous observation.
