Scientific Opportunities for Ultrafast Hard X-rays at High Repetition Rate: An Energy Upgrade of LCLS-II

SLAC National Accelerator Laboratory, Menlo Park, CA,
September 26-27, 2016


Please save the date for an upcoming workshop on Sept. 26-27, 2016:
Scientific Opportunities for Ultrafast Hard X-rays at High Repetition Rate: An Energy Upgrade of LCLS-II
The workshop will be held at SLAC National Accelerator Laboratory, Sept. 26-27, 2016 and will be organized by the Linac Coherent Light Source (LCLS).
Registration will be open soon at the workshop website.
The LCLS-II Project now underway at SLAC represents a major advance in X-ray laser capabilities that will enable compelling new science opportunities as identified by the user community [1]. When it becomes operational in 2020/21 this next-generation LCLS facility will exploit advanced superconducting accelerator technology (continuous-wave RF linac at 4 GeV) and tunable undulators to provide ultrafast coherent X-rays in a uniformly-spaced train of pulses with programmable repetition rates of up to 1 MHz and tunable photon energies from 0.25 to 5 keV.
Looking to the future, the proposed energy upgrade of LCLS-II to 8 GeV (LCLS-II-HE) promises to open entirely new areas of science by providing X-ray energies extending beyond 12 keV to enable high repetition-rate studies of atomic, electronic, and chemical dynamics at the atomic scale.
The objective of this workshop is to further develop the science case for this proposed upgrade, and refine the technical requirements to ensure maximum scientific impact. The results of this workshop will help guide the design and performance capabilities of the upgraded facility; and will inform the planning for new future scientific instrumentation.
