  1. Welcome to the Participants of the ICFA “Future Light Sources” Workshop at Jefferson lab, March 5-9, 2012 Discovery-class Science and Applications to Society via Short-and Long Wavelength Bright and Coherent Pulses of Light SwapanChattopadhyay Director, Cockcroft Institute Sir John Cockcroft Chair of Physics Universities of Liverpool, Manchester and Lancaster

  2. Welcome and Good Morning! The organizers of this wonderful workshop at Jefferson Lab have kindly asked me to say few words about the significance and intrinsic value of long and short wavelength coherent sources of light (from THz to Infrared to X-rays) to science, society and the relevance of this workshop, conceived and co-organised by Jefferson Lab scientists with whatever minimal support I could provide from the Cockcroft Institute, UK. I encourage you to think about not only the great “discovery-class” science that high brightness coherent sources of light promises to enable but also the various societal applications that we could benefit from.

  3. Ultra-bright and Ultra-short pulses of photons and neutrons motivate Ultra-fast and Ultra-small femto- and nano-sciences and their applications (LCLS, XFEL, FLASH, NSLSII, NLS,ERL-based IRFELs, X-ray sources, ISIS, SNS, ESS) Accelerators drive and enable Particle, Nuclear, Photon and Neutron Sciences Particle colliders and accelerators with increasing energies and luminosities probe deeper into the origin of the universe (LHC/LHC+, LHeC, ILC, CLIC, NF/MC, Project-X, Super-B, HIE-ISIOLDE, FRIB, FAIR, RHIC, JLab 12 GeV Upgrade, eRHIC, eLIC,..)

  4. Accelerators also provide Societal Applications Energy, Health, Security Energy: particle-beam assisted fission Lubrication in Nano-Slits Health: Cancer therapy, radio-isotopes, Microwave surgical ablation Security: nano-fabrication for sensors and monitors From Micro- to Nano-Gears Chemistry Lab of Tomorrow: On a Chip Blood Flow in Capillaries

  5. Let’s just look at the Energy issues…..

  6. ENERGY: ACCELERATORS CAN speed up “Nuclear” and “Solar” options for emission-free and environmentally clean minimal waste solutions PV ≡ Photo Voltaics: High efficiency, low cost solar cells: R&D at light sources ADSR: Accelerator-Driven Sub-critical Reactor  High current proton accelerators

  7. CSP ≡ Concentrating Solar Power

  8. sample fs UV pulse Just one example: Developing Next Generation Solar Cells and THz-responsive materials made possible by IRFELs ( work done at the Cockcroft Institute/Daresbury Lab ALICE facility and Univ. of Manchester, Courtesy Prof. Wendy Flavell) The facts: 120 Petawatts of solar energy falls on earth. Our current energy consumption is approx. 15 Terawatts. By 2050, the consumption is expected to double to 30 Terawatts. The problem: we need a step change in the cost of photo-voltaics: volts/$ The Solution: New materials; New approaches Investigate Visible to THz transient absorption via light sources, lasers and particle beams DIAGNOSTICS AREA Multiple Exciton Generation: Step change Mechanism? Funding: EPSRC, Nanoco, STFC, NWSF R. D. Schaller et al., Nano Lett. 6, 424, (2006)

  9. Closing Remarks The Cockcroft Institute is proud to support and join the Jefferson Lab Efforts in promoting the next generation short- and long-wavelength sources of coherent light and enhance the skills base nationally in USA as well as internationally, necessary to make a difference in the world via photon-driven enablers in Energy, Health and Security as we simultaneously explore Discovery-class Science! I wish you a most productive workshop.
