Summary of XDL2011 Workshop - Science at the Hard X-ray Diffraction Limit | |
|
||
| In June, 2011 about 500 individuals participated in a series of 6 workshops at Cornell that were devoted the scientific opportunities of x-ray sources operating near fundamental physical limits from Energy Recovery Linacs and Ultimate Storage Rings. These new sources will provide two to three more orders of magnitude of coherent flux and result in ultra-intense nanometer-scale x-ray probes not yet available and feature short x-ray pulses occurring at MHz to GHz repetition rates with durations of 50 fs to 10s of ps. The consequence will be to provide new imaging opportunities of features approaching atomic resolution and extend repetitive pump-probe experiments to see how materials respond to external stimuli. Participation was very lively and many good ideas were identified. In biology, for example it may be possible to visualize chromosomes, cellular complexes and organelles at 3D spatial resolution of 10 nm or better. In materials science work, the two to three orders gain in coherent flux will allow nanometer-scale imaging of the evolution of a single crystalline grain buried deep inside a thick polycrystalline sample as it changes on a minute time scale when annealed or strained. The workshops were sponsored by CHESS, DESY, KEK, SSRL, DOE and NSF. The material gathered will form a scientific case in support of future coherent, high-duty-cycle, hard x-ray sources. | ||

Beam dynamics for ERLs | |
|
||
| ERLs are Linacs, operated at unusually large currents, and with one or more recirculation loops. The large current produces beam dynamics effects related to: Space charge, halo development from Touschek scattering and rest gas scattering, emittance growth from intra-beam scattering, ion accumulation and ion instabilities. The return loops lead to the re-circulative beam-breakup instability, beam-orbit changes due to higher-order-mode excitations, and the necessity of a small energy-spread budget. These topics will be presented, as investigated for the Cornell ERL. | ||
