TL;DR: In this paper, the authors report on a research and development program underway and in planning at SLAC for addressing critical questions in these areas, including the construction and operation of a linac test stand for developing laser-driven photocathode rf guns with normalized emittances approaching 1 mm-mrad, development of advanced beam compression, stability, and emittance control techniques at multi-GeV energies, and the development of X-ray optics and instrumentation for extracting, modulating, and delivering photons to experimental users.
Initial studies of electromagnetic shower energy deposition in small-bore superconducting undulator structures in linac environments
TL;DR: In this article, the EGS4 particle-tracking code was used to perform studies of scattered-particle energy deposition into superconducting (SC) structures with geometries comparable to a small-bore bifilar helical undulator.
A fast analytical undulator model for realistic high-energy FEL simulations
Roman Tatchyn,T Cremer +1 more
TL;DR: In this paper, a simple analytical model suitable for modeling realistic permanent magnet (PM), hybrid/PM, and non-PM undulator structures is presented, and selected techniques for minimizing computation time are discussed.

Design considerations for a dual-etalon seed-light pre-filter for high-energy LCLS applications
Roman Tatchyn,T Cremer +1 more
TL;DR: In this paper, a flexible seed-light generation and coherence filtering scheme is considered for a 1.5-DOF FEL operating at 15 GeV, which allows the FEL to be operated in a combination of Self-Amplified Spontaneous Emission (SASE) and Coherent Amplifier (CA) modes.
