Targets are an indispensable part of all inertial confinement fusion (ICF) and high-energy-density physics (HEDP) experiments: while a high-quality target does not guarantee the success of an experiment, a poor-quality one can definitely lead to failure. In ICF and HEDP experiments, the precision with which targets are fabricated is critical to obtaining successful results, and many cross-disciplinary scientific and technological challenges are involved in the fabrication process. These include the preparation of submillimeter-sized components with, in many instances, tolerances of tens to hundreds of nanometers, the assembly of these components with micrometer and sub-1000-arcsecond precision, and, finally, full characterization to confirm the dimensional tolerances. Worldwide, more and more researchers and groups are involved in the development of target fabrication techniques, and a great deal of progress has been made. This special issue of the journal Matter and Radiation at Extremes (MRE) on HEDP and ICF target fabrication consists of seven papers, covering the fabrication of target components, target assembly, and characterization.
