Considerations on wakefield effects in a VUV FELO driven by a superconducting tesla-type linac
Alex H. Lumpkin, Henry P. Freund, Peter Van der Slot
The effects on beam dynamics from long-range and short-range wakefields from TESLA-type cavities are considered in regard to a proposed FEL oscillator (FE-LO) operating at 120 nm.…
Three-dimensional, time-dependent analysis of high- and low-Q free-electron laser oscillators
Peter J. M. van der Slot, Henry P. Freund
Free-electron lasers (FELs) have been designed to operate over virtually the entire electromagnetic spectrum from microwaves through x-rays and in a variety of configurations inclu…
Variable Polarization Control in Free-Electron Lasers
H. P. Freund, P. J. M. van der Slot
Free-electron lasers (FELs) over virtually the entire electromagnetic spectrum from microwaves through ultraviolet through hard x-rays that are either seeded or start from noise. F…
High-Efficiency Inductive Output Tubes using a 3rd Harmonic Drive on the Grid
H. P. Freund, R. L. Ives, W. Sessions
In this paper, we discuss the use of a 3rd harmonic component to the drive voltage on the grid of an inductive output tube (IOT). High-efficiency inductive output tubes (IOTs) are…
Comparison of a modal-decomposition and a grid based field solver for free-electron laser simulations
Pietro Falgari, Henry P. Freund, Dennis Grimminck
We present a comparison of the modal-decomposition based field solver MINERVA to the grid-based solver GENESIS. The modal decomposition used employs a set of fixed-width, zero-curv…
Three-Dimensional, Time-Dependent Simulation of Free-Electron Lasers with Planar, Helical, and Elliptical Undulators
H. P. Freund, P. J. M. van der Slot, D. L. A. G. Grimminck +2
Free-electron lasers (FELs) have been built ranging in wavelength from long-wavelength oscillators using partial wave guiding through ultraviolet through hard x-ray that are either…
