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

Sir John Cockcroft Chair of Physics Universities of Liverpool, Manchester and Lancaster

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.

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,..)

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, NSLS II, NLS,ERL-based IRFELs, X-ray sources, ISIS, SNS, ESS)

Accelerators also provide Societal Applications Energy, Health, Security

Chemistry Lab of Tomorrow: On a Chip

Blood Flow in CapillariesFrom Micro- to Nano-Gears

Health: Cancer therapy, radio-isotopes, Microwave surgical ablation

Energy: particle-beam

assisted fission Lubrication in Nano-Slits

Security: nano-fabrication for sensors and monitors

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

10 and 11 November 2008 Presentation to the Science Advisory Committee

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

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

Multiple Exciton Generation: Step change Mechanism?

Investigate Visible to THz transient absorption via light sources, lasers and particle beams

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.
