ANTARES
Cold neutron radiography and tomography facility
This instrument is focussed on cold neutrons. All parameters given here are valid during the current operation of FRM II. Please get in touch with the instrument team well in advance for all further details (length of experiment etc.).
The neutron imaging facility ANTARES is located at the neutron beam port SR-4a of FRM II. Based on a pinhole and flight tube principle (no neutron guide) with a variable collimator located close to the beam port, the facility provides for flexible use in high resolution and high flux imaging.
ANTARES offers two different detector positions, which may be chosen according to the requirements for beam size, neutron flux and spatial resolution. Both chambers offer abundant space for user-provided experimental systems or sample environment.
The beam formation chamber is separately accessible for the optional installation of devices shaping beam and spectrum provided by the user. At this position, ANTARES also offers built-in options such as a velocity selector, neutron grating interferometer and a double crystal monochromator, which are readily available for standard user operation.
The thermal neutron spectrum of ANTARES is shown in fig. 5 (see gallery). ANTARES offers a high neutron flux of approx. 6 · 107 n cm-2 s-1 at a typical collimation of L/D = 500. By using different pinholes the collimation can be adjusted to the requirements of the experiment.
Additionally we can provide access to a 300 kV microfocus X-ray CT setup for complementary investigations with a spatial resolution as good as 1 μm.
The neutron imaging facility ANTARES is designed to deliver radiographs and CTs of samples, which are often complementary to X-ray measurements. The most important features are the high penetration of metals (Fe ~4 – 5 cm, Al ~20 – 30 cm, Pb ~10 – 20 cm) and the high sensitivity for hydrogen. These allow to visualize metal machine parts as well as liquids, sealants, and plastics inside of metal parts. Liquid contrast agents can be employed for crack and void detection. Typical applications are in Archaeology, Paleontology, Biology, Life Sciences, Magnetism and non-destructive testing of mission critical parts.
