Title COBALD - an Inverse Compton Back-Scattering Source at Daresbury
Abstract An inverse Compton Back-Scattering (CBS) ultra-short pulsed x-ray source driven by the multi-terawatt laser installed at Daresbury?s ALICE facility (formally the Energy Recovery Linac Prototype - ERLP) is being developed. Hard x-rays, ranging from 15 keV to 30 keV, depending on the backscattering geometry, will be generated through the interaction of the laser pulse and an electron bunch delivered by ALICE. The x-rays created contain 15×10^6 photons per pulse from head-on collisions, with a pulse duration comparable to that of the incoming electron bunch, and 5×10^6 photons per pulse from side-on collisions, where the laser pulse defines the pulse width. The peak spectral brightness is predicted to be of ≈ 10^20 photons/s/mm^2/mrad^2/0.1% Δλ/λ. Called COBALD, this source will initially be used as a short pulse diagnostic for the ALICE electron beam and will explore the extreme challenges of photon/electron beam synchronization, which is a fundamental requirement for all accelerator-based (whether FEL or spontaneous SR) dynamics programmes.
