Plasma and Laser Accelerators: New Livingston Curve
Nobel prize Physics
2013 Englert/Higgs
• Examples of new ideas and solutions: RF,
AG focusing, beta squeeze, stochastic
cooling, polarized beams, super-
conducting magnets/RF, advanced
materials for vacuum/collimators, plasma
/ laser accelerators, …
• Particle physics in the driver seat for
most of those developments
Nobel prize
Physics 2018
Accelerators are in a continuous technology innovation cycle to
be successful:

Plasma and Laser Accelerator Principle
Damage limits for metallic walls in RF cavities limit accelerating fieldsà replace metal with plasmas or
dielectric materials à advance into the many GV/m regime à shorter acc. lengths à reduced cost?

“Accelerator on a Chip” grant Moore
foundation: Stanford, SLAC, University
Erlangen, DESY, University Hamburg, PSI,
EPFL, University Darmstadt, CST, UCLA
AXSIS ERC Synergy Grant: DESY, Arizona SU
Options for driving plasma and dielectric structures (no klystrons at those frequencies):
• Lasers: Industrially available, steep progress, path to low cost
Limited energy per drive pulse (up to 50 J)
• e- bunch: Short bunches (need µm) available, need long RF accelerator
More energy per drive pulse (up to 500 J)
Tajima & Dawson 1979 • p+ bunch: Only long (inefficient) bunches, need very long RF accelerator
Maximum energy per drive pulse (up to 100,000 J)

• No fundamental show-stopper but a lot of R&D still required.
• There can be very interesting and useful interim steps (non-linear QED, fixed target, dark matter, …)
• Devil is in the details! Answer requires detailed simulation, calculations, R&D, designs and tests!
• How and when can we arrive at readiness for for high energy particle physics, e.g. a TeV collider?
