Abstract
A compact X-ray source based on inverse Compton scattering of a high-power laser on a high-brightness linac beam is described. The facility can operate in two modes: at high (MHz) repetition rate with flux and brilliance similar to that of a beamline at a large 2nd generation synchrotron, but with short ∼1 ps pulses, or as a 10 Hz high flux-per-pulse single-shot machine. It has a small footprint and low cost appropriate for university or industry laboratories. The key enabling technologies are a high average power laser and a superconducting accelerator. The cryo-cooled Yb:YAG laser amplifier generates ∼1 kW average power at 1 μm wavelength that pumps a coherent cavity up to 1 MW stored power. The high-brightness electron beam is produced by a superconducting RF photoinjector and linac operating in CW mode with up to 1 mA current. The photocathode laser produces electron pulses at either 100 MHz with 10 pc per bunch, or at 10 Hz with 1 nC per bunch in the two operating modes. The design of the facility is presented, including optimization of the laser and electron beams, major technical choices, and the resulting X-ray performance with a focus on the 100 MHz mode.
