World-first neutron lens brings sharp focus to structures inside materials and objects

Researchers at Paul Scherrer Institute (PSI) have developed the world's first achromatic lens for neutron imaging.

The lens overcomes a longstanding obstacle in the field: focusing neutrons of different wavelengths well enough to form a sharp, magnified image.

With the lens, researchers can now image thick samples and follow processes inside bulky equipment such as furnaces, cryostats or pressure cells. ...
