  • Effectiveness and limitation of the periodic boundary approximation in the analysis of single-pass electron beam devices

    The effectiveness and limitation of the periodic boundary condition (PBC) in the analysis of single-pass electron beam devices are discussed. A Cherenkov traveling-wave amplifier consisting of a dielectric-loaded parallel plate waveguide and a planar relativistic electron beam is picked up as an example of electron beam devices. The numerical results obtained without the PBC are compared with those obtained with the PBC. Then, errors caused by the approximation are found to be mainly attributed to two factors. One is caused by the initial condition, which is inherent to the analysis with the PBC. The other factor is the magnitude of the growth rate. The upper bound for the growth rate is given for which the analysis with the PBC is valid. The analysis with the PBC could be effective for estimating energy transfer efficiency because of its relatively small error and significantly low computational cost.

  • Photonic-band-gap (PBG) and metamaterial RF-structures for high power millimeter and THz wave electron beam devices

    Novel photonic band gap (PBG) waveguides and metamaterial (MM) cavities have been designed in the effort to develop high power millimeter and THz sources. The designed structures are comprised of a periodically corrugated channel sandwiched between two PBG slabs and a multi-cell cavity-resonator designed with fishnet apertures. The simulation analysis shows that trapped non-PBG modes are effectively suppressed down to ~ - 14.3 dB/cm, while PBG modes propagated with ~ 2 dB of insertion loss, corresponding to ~1.14 dB/cm attenuation. The preliminary modeling analysis on the fishnet-embedded cavity shows noticeable improvement of Q-factor and field gradient of the operating mode (TM<sub>010</sub>) compared to those of typical pillbox- or PBG-cavities. The Ka-band PBG-waveguide and S-band fishnet cavity structures will be tested with a microwave test bench/8510C Network Analyzer and 5.5 MW S-band klystron. These structures can be applied to stable short-bunch formation and mono- energetic radiation in high frequency electron beam devices.

  • 3-D modeling of electron beam devices

    Summary form only given. New advanced analysis codes are allowing design and development of a new generation of electron devices. The ability to simulate 3D structures and electron beam propagation in non-symmetric, electromagnetic fields provide design capabilities that were not available a few years ago. In the last few years, Calabazas Creek Research, Inc. (CCR) has used its 3D analysis code Beam Optics Analyzer (BOA) to simulate single and doubly convergent multiple beam klystrons, gridded cathodes, advanced lighting fixtures, periodic permanent magnet (PPM) focused multiple beam klystrons, bombarders for electron beam of cathodes, the effect of cathode tilt and offset on beam propagation in a single beam electron gun. Other BOA users are developing advanced x-ray devices, including the effects of secondary electron emission in non-symmetric fields.

  • MAGY: a self-consistent code for modelling electron beam devices

    Summary form only given, as follows. MAGY is a quasi three dimensional self consistent time dependent code for modeling of electron beam systems. We assume that the system consists of a cylindrically symmetric waveguide with an arbitrarily varying wall radius (including jump discontinuities) and represent the electromagnetic fields as a set of transverse electric and transverse magnetic modes which are defined by the local value of the wall radius. We thus obtain a set of coupled transmission line equations for the voltage and current amplitudes of the various modes. The coupling of the modes originates in the variations of the wall radius, finite conductivity of the walls and the electron beam. We describe the electron dynamics using the guiding center formulation of the equations of motion with an arbitrary profile of the guiding magnetic field. A significant simplification of these equations is obtained when all the particles traverse the cavity in a time shorter than the cavity fill time. The combined set of equations for the electromagnetic amplitudes and the electron trajectories form the reduced description we are employing in the MAGY code. In the work we present first results obtained with the new MAGY code for generic Gyrodevices and a Backward Wave Oscillator.

  • Compact semiconductor-based Marx generator design for microsecond pulsed electron beam devices

    Summary form only given. For microsecond pulsed electron beam facilities with explosive emission cathodes a new semiconductor-based generator has been develop. This novel design concept comprises a unipolar Marx configuration, which is designed for a rectangular voltage of 120 kV and a maximum current of 150 A at a pulse length of up to 50 microsecond. A fast rise of the voltage within less than 100 ns is required to foster an instantaneous plasma generation at the cathode. Hence, fast switching is necessary. The paper describes aspects of the design of the semiconductor-based pulse generator. The charging path of the circuit comprises diodes in the ground-side branch and IGBTs in the high-voltage side branch. This connection also results in a parallel configuration of the capacitors during charging. For pulse generation the capacitors are switched in series such, that the polarity of the pulse is inverted with respect to the charging voltage. With such circuit a rectangular pulse can be generated, if the switches are capable of breaking the current and the stage capacitors are chosen large enough that the voltage droops due to discharge is negligible. Keeping the voltage constant should prevent cathode plasma from bridging the acceleration gap.

  • Numerical modeling of axisymmetric electron beam devices using a coupled particle-finite element method

    A coupled particle finite-element method is developed for the numerical resolution of the time-dependent relativistic Vlasov-Maxwell equations in axisymmetric geometries. The use of a conforming finite-element method for the Maxwell solver supplemented with a mass-lumping technique leads to an explicit system for the computation of the electromagnetic fields components. For the Vlasov solver, a fully vectorized algorithm is used for the location of the particles in an unstructured mesh made up with triangles. The numerical values of the electromagnetic fields radiated by a dipole are compared with the analytical solution. The whole Vlasov-Maxwell solver is tested on a simplified free-electron laser electron injector, designed for an RF-based free electron laser and the results are compared with those obtained with a finite- difference code.<<ETX>>

  • Computational Design of Asymmetric Electron Beam Devices

    Three-dimensional design codes are allowing the development of more complex electron beam devices with significant performance improvements over axially symmetric devices. Distributed beam RF devices, including multiple-beam and sheet-beam designs, allow significant reduction in operating voltage with improved efficiency and bandwidth. The increased parameter space, however, makes the design process extremely complicated and costly. This paper describes optimization techniques to automate the most time-consuming tasks of the design, which is searching the available parameter space to optimize performance. Both sheet-beam and multiple-beam designs are considered.
