Description
Jefferson Lab (JLab) is proposing JLAMP (JLab AMPlifier), a 4th generation light source covering the range 10–100 eV in the fundamental mode with harmonics stretching towards the oxygen k-edge. The scientific purpose is to study ultrafast dynamics in complex systems as a pathway to the understanding and creation of novel materials and devices. The machine will be based on an energy upgrade to an existing energy-recovering linear accelerator at JLab, made possible by advances in superconducting accelerator technology. Specifically, accelerating gradients of 20 MV/m and electron-beam recirculation will allow electron-beam energies of >600 MeV to be achieved at repetition rates up to 4.68 MHz with continuous wave RF. The RF systems for the machine will operate at 1497 MHz, 748.5 MHz and 187.125 MHz. The average brightness will substantially exceed existing light sources in this device's photon energy range, and in addition, multiple photon sources will be made available for pump-probe dynamical studies. The system will be capable of operating as a seeded amplifier for precise pulse length and bandwidth control or as an oscillator at higher average brightness. An overview of the accelerator with specific details relating to the RF systems will be presented.
