The accelerator physics and technology of hadron colliders, heavy quark factories, and linear colliders are reviewed. The status and performance of major high energy accelerators are summarized.

The article discusses in general terms the state of the art of collective ion accelerator technology and the prospects of further development and applications of ultrahigh energy accelerators. (Author)

International Linear Collider (ILC) as nearing the ceiling for an accelerator's physical size. "Right now, high-energy physicists are building accelerators that are...

Accelerator science and technology have evolved as accelerators became larger and important to a broad range of science. Physical Review Special Topics - Accelerators and Beams was established to serve the accelerator community as a timely, widely circulated, international journal covering the ...

All of the papers in this Special Issue highlight the role collective plasma processes play in accelerating particles or generating radiation. Some are state-of-the-art presentations of the latest research in a single discipline, while others investigate the applicability of known laboratory mechanisms to explain observations in natural plasmas. The papers ...
