Free electron laser in magnetically dominated regime: simulations with ONEDFEL code
Maxim Lyutikov, Henry Freund
Using the ONEDFEL code we perform Free Electron Laser simulations in the astrophysically important guide-field dominated regime. For wigglers' (Alfven waves) wavelengths of tens of…
High Efficiency, Low Cost, RF Sources for Accelerators and Colliders
R. Lawrence Ives, Michael Read, Thuc Bui +9
Several high efficiency, low cost, RF sources are in development or recently completed. All are designed to provide operating efficiencies exceeding 80% and provide more than 100 k…
Analysis of Ultra-Short Bunches in Free-Electron Lasers
Lawrence Campbell, Henry Freund, James Henderson +3
Free-electron lasers (FELs) operate at wavelengths from millimeter waves through hard x-rays. At x-ray wavelengths, FELs typically rely on self-amplified spontaneous emission (SASE…
Efficiency enhancement in regenerative amplifier free-electron lasers using a tapered undulator
Henry Freund, Peter van der Slot, Patrick O'Shea
Recent progress in short wavelength free-electron lasers extending from the extreme ultraviolet through the x-ray regime have opened new avenues for industrial and research applica…
