Free-Electron Lasers with Electromagnetic Standing Wave Wimlers
Abstrucf-A detailed analysis of the electroniagnetic standing wave wiggler for free-electron lasers (FEL’s) is conducted for both circular and linear wiggler polarizations, following a single-particle approach. After determination of the unperturbed electron orbits in the wiggler field, the single-particle spontaneous emission spectrum and subsequently the gain in the low gain Compton regime (u...
متن کاملA Scanned Perturbation Technique For Imaging Electromagnetic Standing Wave Patterns of Microwave Cavities
We have developed a method to measure the electric field standing wave distributions in a microwave resonator using a scanned perturbation technique. Fast and reliable solutions to the Helmholtz equation (and to the Schrödinger equation for two dimensional systems) with arbitrarily-shaped boundaries are obtained. We use a pin perturbation to image primarily the microwave electric field amplitud...
متن کاملBeam Dynamics in a Hybrid Standing Wave- Traveling Wave Photoinjector
We discuss the dynamics of of a photoinjector beam in a hybrid traveling wavestanding wave photoinjector. With the field profile deduced from electromagnetic simulations, it is seen that the acceleration program induces strong velocity bunching. The beam dynamics in this scenario are explored using UCLA PARMELA. With a solenoid field overlaid on the TW section one may control emittance oscillat...
متن کاملStanding-wave interferometer
An interferometric position sensor was developed using the concept of sampling a standing wave. Interference of a standing wave created in front of a plane mirror can be detected by thin, partly transparent sensors based on amorphous silicon. The optical thickness of the absorption layer is thinner than the wavelength l of the incident light. Detection of minima and maxima of the standing wave ...
متن کاملEFFECTIVE EXCHANGE INTEGRAL (J1 + J2) IN EuS FROM STANDING SPIN WAVE RESONANCE
The standing spin wave resonance has been measured in thin films of EuS at 1.1 OK in the perpendiculai configuration. The magnon dispersion relation is found to be quadratic in the observed region of k (k < 0.2 xla). The effective exchange energy (JI $. Jz) determined is 0.088 f 0.010 OK. This value is lower than that calculated by Passenheim et al. [7] from specific heat measurements. This dis...
