content• High fields that break matter, but keep order

Guiding principle for order: not atomic cohesion (quantum coherence), but relativistic coherence

• High energy accelerators by laser• Low luminosity opportunities in high energies• Luminosity issue for collider---ICUIL-ICFA Joint Task• Answer to high rep rate and high efficiency fiber laser (CAN)• Laser (not charged particles) collider for Dark Fields search• CAN lasers : enabling technology also for industrial and societal

applications: compact radiation oncology, directed gamma beams (nuclear medicine and pharmacology), homeland security, transmutation of nuclear wastes (ADS, etc.) , ….

• Movie: about the future of CAN lasers

IZEST’s Mission:Responding to Suzuki’s Challenge

Greetings from Michel Spiro(Former) President of CERN Council

As President of the CERN Council, I would like to express our interest and warm support in developing new ultra highgradient techniques of particle acceleration.Plasma acceleration seems a very promising avenue. The IZEST project is a bold and fierce adventure. It willopen the way to a new generation of ultra high energyand compact accelerator and give access to totally new physics like probing quantum vacuum and testing thebasic laws of physics. I wish great success to the IZEST conference and to the IZEST project.

Best wishes,Michel

[Court. A. Oeftinger(CERN]

Smart control of laser

Emittance (and thus luminosity) of the particle beamrapidly increases with the jitters of laser [in multi-stage acceleration]smart control of laser contains jitters

We see:CAN laser property of smartness

higher rep rate, easier to operate CAN laserhigher rep rate, easier to feed-forward controlfeedforward control quality of beamsCAN laser : coherently connected (both in parallel, but also in tandem)each fiber (digital unit): coherently and digitally controllable

digitally controlled smart laser : a new paradigm

Linear collider (ILC @ 250GeV x 250GeV)~8MW (in beams), cost for accelerators ~ 4GEuro

~500Euro / W (beam)Laser-driven collider (if we design @ 250GeV x 250GeV)

same at 8MW (in beams)diode 7*Euro / W x 3 (to give total optics) = 21Euro/W

assume efficiencies: laser/wallplug =0.5, compressor=0.4, excitation of wake=0.4, acceleration=0.5. total efficiency = 0.04~500Euro/W (beam)

however, (1) far less other cost s.a. civil eng., (2) *could come down substantially(a) yet to be demonstrated. [laser path after the current plan]
