Story summary
- PSI scientists unveiled the achromatic neutron lens that focuses a broad range of neutron wavelengths.
- The lens, made of nickel rings thinner than 200 nm and diamond elements from SYNOVA S.A., achieves sub-20 µm resolution and produced a sevenfold magnified image of a lithium-ion battery six metres away.
- Prototypes tested at the Swiss Light Source and SINQ showed performance, suggesting that beamlines such as the European Spallation Source could increase magnification.
