Abstract: A plane wave transformer linear accelerator structure for accelerating charged particles to velocities greater than one-half the speed of light. The accelerator includes a tank section having a generally cylindrical tank wall. End plates each containing a central aperture for accommodating the passage of a charged particle beam are positioned adjacent to the ends of the tank wall. Support rods extend between the end plates, partially defining at least one axially-extending outer cavity and at least one axially-extending inner cavity. A plurality of axially-spaced washers situated substantially on the central axis of the tank section are supported by the rods. The washers each have central apertures which together define a charged particle beam acceleration path through the tank section.

Abstract: A coupled-cavity linear accelerator for accelerating charged particles to velocities greater than about one-third the speed of light. The accelerator includes a first tank for accelerating charged particles at a first velocity to a second velocity and a second tank for accelerating the particles to a higher third velocity. A bridge coupler for focusing a beam formed by the charged particles joins the first and second tanks. Each tank is substantially symmetrical about an axis and includes a generally cylindrical tank outer wall having an inner surface and an outer surface. A series of axially spaced disks are positioned inside the tank and bear on the inside tank surface. Each disk has an outer diameter greater than the as-manufactured inside diameter of the tank wall so that each disk causes an annular indentation in the inner surface of the outer wall. At least one washer is supported by each of alternating disks. These washers have central apertures which together define a particle beam acceleration path through the tank. Methods of fabricating the linear accelerator and of tuning it are also disclosed.

Abstract: A free electron laser system and electron beam system for a free electron laser which use rf feedback to enhance efficiency. Rf energy is extracted from an electron beam by decelerating cavities and returned to accelerating cavities using rf returns such as rf waveguides, rf feedthroughs, etc. This rf energy is added to rf klystron energy to lower the required input energy and thereby enhance energy efficiency of the system.

Abstract: An interdigital (Wideröe) linear accelerator employing drift tubes, and associated support stems that couple to both the longitudinal and support stem electromagnetic fields of the linac, creating rf quadrupole fields along the axis of the linac to provide transverse focusing for the particle beam. Each drift tube comprises two separate electrodes operating at different electrical potentials as determined by cavity rf fields. Each electrode supports two fingers, pointing towards the opposite end of the drift tube, forming a four-finger geometry that produces an rf quadrupole field distribution along its axis. The fundamental periodicity of the structure is equal to one half of the particle wavelength βλ, where β is the particle velocity in units of the velocity of light and λ is the free space wavelength of the rf. Particles are accelerated in the gaps between drift tubes. The particle beam is focused in regions inside the drift tubes.

Abstract: A linear accelerator of the interdigital (Wideröe) type, employing two-part drift tubes and associated support stems that couple to the electromagnetic fields of the interdigital linac structure, creating rf quadrupole fields along the axis of the linac to provide transverse focusing for the particle beam. Each two-part drift tube comprises two separate electrodes that operate at different electrical potentials. Each electrode supports two fingers, pointing inwards towards the opposite end of the drift tube, forming a four-finger geometry that produces an rf quadrupole field distribution along its axis. The fundamental periodicity of the structure is equal to one half of the particle wavelength &bgr;&lgr;, where &bgr; is the particle velocity in units of the velocity of light and &lgr; is the free space wavelength of the RF. Particles are accelerated in the gaps between drift tubes. The particle beam is focused in the regions inside the drift tubes.

Abstract: A free electron laser and free electron laser amplifier using beam transport devices for guiding an electron beam to a wiggler of a free electron laser and returning the electron beam to decelerating cavities disposed adjacent to the accelerating cavities of the free electron laser. Rf energy is generated from the energy depleted electron beam after it emerges from the wiggler by means of the decelerating cavities which are closely coupled to the accelerating cavities, or by means of a second bore within a single set of cavities. Rf energy generated from the decelerated electron beam is used to supplement energy provided by an external source, such as a klystron, to thereby enhance overall efficiency of the system.

Abstract: A catalac free electron laser using a rf linac (catalac) which acts as a catalyst to accelerate an electron beam in an initial pass through the catalac and decelerate the electron beam during a second pass through the catalac. During the second pass through the catalac, energy is extracted from the electron beam and transformed to energy of the accelerating fields of the catalac to increase efficiency of the device. Various embodiments disclose the use of post linacs to add electron beam energy extracted by the wiggler and the use of supplementary catalacs to extract energy at various energy peaks produced by the free electron laser wiggler to further enhance efficiency of the catalac free electron laser. The catalac free electron laser can be used in conjunction with a simple resonator, a ring resonator or as an amplifier in conjunction with a master oscillator laser.
