Current Status of Collective Accelerators

The paper is based on the 3rd International Conference on Collective Methods of Acceleration held at Laguna Beach in May 1978. Current status is considered for the Electron Ring Accelerator (ERA) Auto Resonant Accelerator (ARA), Ionization Front Accelerator (IFA), magnetically insulated ion diodes, Luce Diodes, and some more recent ideas, such as the Collective Focusing Ion Accelerator and Pulselac, where magnetic fields control the electron dynamics and electron space charge controls the ions.
