“…To date, energy recovery has been realized in a number of different ways. The first energy recovery experiment was done at Stanford's superconducting rf (srf) linac where the recirculated electron beam was injected into the linac in such a phase that it lost energy to the cavity fields [1]. This is an example of the so-called same-cell energy recovery.…”

We present the design of high-luminosity electron-proton/ion colliders in which the electrons are produced by an Energy Recovering Linac (ERL). Electronproton/ion colliders with center of mass energies between 14 GeV and 100 GeV (protons) or 63 GeV/A (ions) and luminosities at the 10 33 (per nucleon) level have been proposed recently as a means for studying hadronic structure. The linac-on-ring option presents significant advantages with respect to: 1) spin manipulations 2) reduction of the synchrotron radiation load in the detectors 3) a wide range of continuous energy variability. Rf power and beam dump considerations require that the electron linac recover the beam energy. Based on extrapolations from actual measurements and calculations, energy recovery is expected to be feasible at currents of a few hundred mA and multi-GeV energies. Luminosity projections for the linacring scenario based on fundamental limitations are presented. The feasibility of an energy recovery electron linac-on-proton ring collider is investigated and four conceptual point designs are shown corresponding to electron to proton energies of: 3 GeV on 15 GeV, 5 GeV on 50 GeV and 10 GeV on 250 GeV, and for gold ions with 100 GeV/A. The last two designs assume that the protons or ions are stored in the existing RHIC accelerator. Accelerator physics issues relevant to proton rings and energy recovery linacs are discussed and a list of required R&D for the realization of such a design is presented.

“…The basic principles of energy recovery have been demonstrated experimentally [9], but energy recovery at high average beam current with an FEL increasing the energy spread of the exhaust beam has not been demonstrated. Transport must be nearly lossless &om -199 MeV down to the beam dump at 10 MeV.…”

Vacuum electronic sources have shown marked improvement since the invention of the magnetron before World War II, and dramatic increases in both average powers and frequencies have been achieved. Of course, much of these gains have been achieved by the development of different devices. The typical development pattern for a given device exhibits an initial period of rapid improvement followed by a plateau determined by technological or physical limitations on the concept. Slow wave devices such as magnetrons and/or klystrons operate efficiently at frequencies up through X-band or he source of the relation ed cavity traveling wave tubes are used for various applications at frequencies ranging up through W-band. At still higher frequencies fast wave devices such as gyrotrons and free-electron lasers are required are required for high power operation.The free-electron laser concept is unique in that the mechanism is applicable across the entire electromagnetic spectrum, and free-electron lasers have been built at wavelengths from microwaves through the ultraviolet, and plans are under development for X-ray systems. Our purpose of this paper is to describe the principal directions of free-electron laser research at the present time. To this end, we first give a brief tutorial of the physics underlying the concept, and then describe the principal development paths under way.
