Abstract

We present here the theory and computational modeling of beams in a new regime, where ∼1 pC beams are strongly velocity bunched at low energy, and then compressed at the GeV level to ≤ fsec. This regime of operation produces beams with thermally dominated transverse emittance, and mitigates many problems associated with the nC-level operation. These problems include CSR induced instability and intra-undulator wakes. The resulting beams have extremely high brightness, enabling very high gain, efficiency, and single spike operation. We present here a detailed design example, that of the proposed SPARX FEL design.
