Target class: ultraviolet light source Context triple: [FERMI free-electron laser, instanceOf, ultraviolet light source]
-
A.
neutron source
A neutron source is a device or material system that produces and emits neutrons for applications such as scientific research, medical treatments, industrial inspection, and nuclear technology.
-
B.
Raman spectrometer
A Raman spectrometer is an analytical instrument that uses monochromatic light to measure inelastically scattered photons from a sample, providing molecular vibrational information for chemical identification and characterization.
-
C.
pulsed neutron source
A pulsed neutron source is a facility or device that generates short, intense bursts of neutrons for applications such as materials research, nuclear physics experiments, and imaging.
-
D.
solar-powered light installation
A solar-powered light installation is an artistic or functional lighting system that harnesses sunlight via photovoltaic panels, stores the energy, and automatically illuminates spaces without relying on external power sources.
-
E.
fluorescence spectrometer
A fluorescence spectrometer is an analytical instrument that measures the intensity and wavelength distribution of fluorescent light emitted by a sample after excitation with a specific light source, enabling qualitative and quantitative analysis of molecular species.
- F. None of above. chosen
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
