Detection of space-charge-dominated dynamics through charge tuning.
Validation of the tomography method at FACET-II.
Abstract
We present transverse phase space tomographic reconstruction of the two-bunch configuration at FACET-II. We demonstrate diagnosing two superimposed electron bunches with different transverse phase spaces using a single quadrupole scan. Tuning the bunch charge revealed unexpected space-charge-dominated dynamics.
