Transverse phase space tomography at FACET-II
Abstract
We present recent development of transverse phase space tomographic reconstruction techniques at FACET-II. We present implementation of such techniques in the FACET-II injector, and utilize it to characterize the two-bunch from photocathode configurations. We demonstrate the characterization of two-bunch phase space misalignment and its potential control and application in PWFA experiments. We also characterize the effect of transverse space-charge force by varying two-bunch charge ratio. We also present single-shot and multi-shot tomographic reconstruction of electron spectroscopy image for PWFA-accelerated beam characterization.
