ANTARES

The neutron imaging facility ANTARES is located at the neutron beam port SR-4a. 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 environments.

The beam formation chamber is separately accessible for the optional installation of devices shaping the beam and spectrum provided by the user. At this position, ANTARES also offers built-in options such as a velocity selector, a neutron grating interferometer and a double crystal monochromator, which are readily available for standard user operation.

The spectrum of ANTARES is shown in fig. 1 (see gallery). ANTARES offers a high neutron flux of approx. 6.3 × 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 experiment’s requirements. Additionally, we can provide access to a microfocus X-ray CT set-up for complementary investigations with a spatial resolution as good as 1 μm. More information [MLZ Garching]
