The Electron-Ion Collider (EIC), which is being designed by BNL, JLab and other partners, will be a particle accelerator that collides electrons with protons and nuclei to produce snapshots of those particles’ internal structure. It will collide polarized high-energy electron beams with hadron beams in the center-of-mass energy range of 20-140 GeV. The electron beam, employed as a probe, will...
The Advanced Photon Source (APS) has recently completed a major upgrade, replacing its 25-year-old storage ring with a cutting-edge hybrid seven-bend achromat lattice enhanced by six additional reverse bends. The new design achieves a natural emittance of 42 pm-rad, enabling the production of X-rays up to 500 times brighter than those generated by the original APS. A key innovation of the...
The LCLS-II upgrade has expanded the capabilities of the Linac Coherent Light Source (LCLS), extending the deliverable photon energy range and increasing the repetition rate from 120 Hz to a maximum of 1 MHz. Here we report the development of attosecond X-ray science capabilities at the LCLS-II, including the commissioning of beam shaping methods for attosecond pulse generation, and the...
