The gamma-ray binary HESS J0632+057

Gamma rays are the most energetic known form of electromagnetic radiation, with each gamma-ray being at least one hundred thousand times more energetic than an optical light photon. Very high energy (VHE) gamma rays pack ...

Lasers light up neutron generation for radiography

Getting snapshots of systems and processes at precise time points is important to research and development in many fields, including biology, materials science, and engineering. Firing a neutron beam at a material is one ...

Simulations examine performance of materials in NIF experiments

Scientists have examined the performance of pure boron, boron carbide, high-density carbon and boron nitride ablators—the material that surrounds a fusion fuel and couples with the laser or hohlraum radiation in an experiment—in ...

Tracking down the mystery of matter

Researchers at the Paul Scherrer Institute PSI have measured a property of the neutron more precisely than ever before. In the process they found out that the elementary particle has a significantly smaller electric dipole ...
