Neutron Radial

The radial collimator has foils angled in the horizontal plane, often assembled in a large angular range or even a 360 degrees frame.

Among our large variety of radial collimators, you will find circle collimators with more rough collimation as well as fine small-angled systems.

Many radial collimators are used inside vacuum vessels and are produced with vacuum compatible parts and coating. Several examples can be seen in our collimator catalog.

Also, we have designs for stepped radial collimation systems in which a large number of soller collimators are positioned radially around a sample.
