abstract:	The possibility of amplifying two frequencies simultaneously in a free electron laser is discussed. Stability conditions for electron motion are derived, and numerical calculations reported. The advantages offered by using a DC Pelletron beam to power such a device, with application to the plasma beatwave accelerator-high efficiency, high average power, radiation wavelength tunability, and the possibility of phase locking several independent optical cavities-are evaluated. Related research efforts, and their impact on the design of this device, are discussed. (10 References).

abstract:	The prospect of achieving very high accelerating fields has led to proposals for using electrostatic plasma waves to accelerate charged particles for high energy physics. It has been predicted theoretically that these plasma waves can be driven by the wake fields of short bunches, or trains of bunches, of charged particles, to accelerate a subsequent bunch; the longitudinal electric fields could possibly be of the order of a few GV/m. The authors present an outline of a proposed experimental test of this principle. (14 References).
