Explore the history of Stanford Linear Accelerator Center, electron/positron accelerators, synchrotron radiation, and free electron lasers. Learn about key milestones, including the first high-field SRF cavities and demonstration of a Free Electron Laser oscillator. Discover the journey from the inception of the SLAC Linear Collider to the commissioning of the Linac Coherent Light Source. Join us in commemorating the advancements in accelerator technology and project milestones from 1962 to the project's completion in 2009.

Welcome to the LCLS Commissioning Workshop John N. Galayda Director of LCLS Construction
Stanford Linear Accelerator Center • Operated by Stanford University • For the US Deparment of Energy • Electron/positron accelerators • Synchrotron radiation • Free Electron Lasers
Three km Two Mile Linac 1962: Start of accelerator construction 1967: 20-GeV electron beam achieved
Hansen Experimental Physics Laboratoryat Stanford University • (1962) First high-field, high-Q SRF cavities • (1965) First electron acceleration by an SRF cavity • (1972) First superconducting linear accelerator • (1976) First demonstration of a Free Electron Laser oscillator. • (1980) First SRF linac with beam recirculation for energy multiplication. • (1985) First demonstration of same-cell energy recovery. • (1990) Established Infrared FEL Optics Center based on the SRF linac.
1998: First colliding beams PEP Colliding Beam Facility A collaborative project: SLAC and LBNL 1980: PEP operations begin 1987 PEP tested as a synchrotron source Brighter than APS, SPring-8 design goals
SLAC Linear Collider • 1989: SLC operations begin, 50 GeV electron and positron beams achieved • Power-pulse compression using SLAC Energy Doubler (SLED) • The first linear collider – a commitment to the long-range future of high energy electron machines • SLAC Linear Collider • 50 GeV electron and positron beams in collision • Power-pulse compression using SLAC Energy Doubler (SLED) • The first linear collider, 1989-1998

It’s Time to Turn On • Injector Commissioning Preparations & Planning • FEL commissioning requires a stable, well-understood injector • We have about one year of studies time to get the injector working smoothly • We are grateful for your presence and help in this workshop
It’s Time to Turn On • Sincere Thanks!
