Objective
Neutrons can be guided in glass capillaries by total reflection under very flat angles, generally less than 0.5 degrees between the direction of the neutrons and the inner wall of the capillary. Khumakhov has used this phenomenon to develop neutron lenses consisting of large bundles of capillaries which are bent so as to focus a parallel beam into a small, ca. 1 mm{2}, focusing area.
The goal of this project is to investigate the characteristics of neutron lenses and to develop lenses for specific applications in medicine and material sciences. Lenses for neutrons of thermal energy and of sub-thermal energy (cold neutrons) will be constructed in Moscow according to specifications derived in co-operation with the west European partners. They are also to be tested in Moscow and in the participating laboratories in western Europe using research reactors as the principal neutron sources.
Starting from the experience gained in these tests the lens designs will further be optimised for the specific fields of application.
