Longitudinal stability in multiharmonic standing wave linacs

Particle Enrichment in Longitudinal Standing Bulk Acoustic Wave Microfluidics

Analyses and Simulations of Longitudinal Motion in μ-Recirculating Linacs

We present an analysis of the acceleration scenario for a high-energy μμ collider. Acceleration from GeV to TeV energies is required, accompanied by bunch compression to colllider-scale bunch lengths. The baseline scenario is a cascade of recirculating linacs (RLAs), with each linac increasing the beam energy by an order of magnitude. Bunch compression can occur both in the linacs themselves an...

Standing-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 ...

Beam 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...

Standing Wave Decomposition Gaussian Process

We propose a Standing Wave Decomposition (SWD) approximation to Gaussian Process regression (GP). GP involves a costly matrix inversion operation, which limits applicability to large data analysis. For an input space that can be approximated by a grid and when correlations among data are short-ranged, the kernel matrix inversion can be replaced by analytic diagonalization using the SWD. We show...
