Cover Story: The High Energy cosmic-Radiation Detection facility (HERD) will be one of the main experiments onboard the China Space Station. HERD is planned for installation in 2027, and it will operate for at least 10 years. Its novel design optimizes its acceptance per weight, featuring a central 3D-imaging calorimeter that is accompanied by complementary subdetectors on five sides. HERD will study the cosmic ray spectrum and composition, reaching the PeV energy range and performing indirect-dark-matter-detection studies. With a dedicated low energy gamma ray trigger, it will be capable of detecting gamma rays down to ~100 MeV, enabling its use as a full-sky gamma ray observatory. View this paper

Niobium as Preferential Material for Cyclotron Target Windows

  • Sergio J. C. do Carmo and
  • Francisco Alves

The present work promotes and validates the benefits of using niobium instead of Havar® as the material for the target windows in most routine irradiations in cyclotrons. Calculation of the material activation and measurements of the contaminatio...

  • Christopher Hulme,
  • Panagiotis Tolias,
  • Gavin Poludniowski and
  • Mats Danielsson

The spatiotemporal resolution of diagnostic X-ray images obtained with rotating-anode X-ray tubes has remained limited as the development of rigid, high-performance target materials has slowed down. However, novel imaging techniques using finer detec...
