MIT inverse Compton source concept

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