摘要： A focused optical is been used to introduce an optical pulse, or electromagnetic wave, colinearly with the electron beam in a free electron laser or synchrotron thereby adding an axial field component that accelerates the electrons on the radial outside of the distribution of electrons in the electron beam. This invention consists of using the axial electrical component of a TEM.sub.10 mode Gaussian beam in vacuum to condition the electron beam and speed up the outer electrons in the beam. The conditioning beam should possess about the same diameter as the electron beam. The beam waist of the conditioning wave must be located around the entrance of the undulator longitudinally to have a net energy exchange between the electrons in the outer part of the distribution and the conditioning wave owing to the natural divergence of a Gaussian beam. By accelerating the outer electrons, the outer and core electrons are caused to stay in phase. This increases the fraction of the electron beam energy that is converted to light thereby improving the efficiency of conversion of energy to light and therefore boosting the power output of the free electron laser and synchrotron.

摘要： A method for decelerating beams of charged particles that have been accelerated using a linear accelerator. The high-energy particles, such as electrons, are passed through a series of induction cells, each of which generates an electrical pulse as a packet of electrons passes through it and has its velocity reduced. The energy removed from the packets of electrons in the form of electrical pulses can either be stored for later use or discharge, or can be immediately employed to accelerate other electrons in an associated linear accelerator.

摘要： A method of large-scale active THz imaging using a combination of a compact high power THz source (>1 watt), an optional optical system, and a camera for the detection of reflected or transmitted THz radiation, without the need for the burdensome power source or detector cooling systems required by similar prior art such devices. With such a system, one is able to image, for example, a whole person in seconds or less, whereas at present, using low power sources and scanning techniques, it takes several minutes or even hours to image even a 1 cm×1 cm area of skin.

摘要： A focused optical beam is used to change the path length of the core electrons in electron light sources thereby boosting their efficiency of conversion of electron beam energy to light. Both coherent light in the free electron laser and incoherent light in the synchrotron is boosted by this technique. By changing the path length of the core electrons by the proper amount, the core electrons are caused to stay in phase with the electrons in the outer distribution of the electron beam. This increases the fraction of the electron beam energy that is converted to light thereby improving the efficiency of conversion of energy to light and therefore boosting the power output of the free electron laser and synchrotron.

摘要： A free-electron laser including one or more diffraction gratings as part of a resonator structure, to automatically compensate for resonator reflector pointing errors. The angle of reflection of radiation incident on the diffraction grating is frequency-dependent, and this permits compensation of the pointing errors by small shifts in the frequency of operation of the laser, within its normal bandwidth of operation. The technique may be employed in various resonator structures, including a ring resonator.
