The recent major discoveries in particle physics have motivated further the needs of new large scale accelerators, accompanied with outstanding scientific and technological challenges. After a brief summary on the status of the field, we will present in this talk the various scientific directions, which these discoveries open. We will then discuss the different types of particle accelerators...

The European Network for Novel Accelerators (EuroNNAc) is part of the European Accelerator R&D (EuCARD2) project and aims at providing a forum for discussion and coordination of advanced accelerator R&D in Europe. Presently it has 52 member institutes with a majority from Europe but also strong links to American and Asian research leaders. The talk will discuss the role that EuroNNAc can play...

ELI Nuclear Physics, one of the 4 pillars of ELI, will be built in Bucharest-Magurele, Romania. It is meant as an unique research facility to investigate the impact of very intense electromagnetic radiation (Extreme Light) on matter with specific focus on nuclear phenomena and their applications. The extreme light is realized at ELI-NP in two ways: by very high optical laser intensities and by...

The Extreme Light Infrastructure ELI will be the world's first international user facility for the scientific laser community. It is part of the ESFRI Roadmap for Pan-European Research Infrastructures of high priority, and it is presently being constructed as a de-centralized facility in the Czech Republic, Hungary and Romania. ELI will be instrumental for establishing and exploiting new...

The large existing astronomical telescopes - Very Large Telescope, Gemini, Subaru, Large Binary Telescope or Keck telescope - include primary mirrors of about 10 meters in diameter. More, they deliver images close to the diffraction limit thanks to new technologies such active and adaptive optics.
A new generation of telescopes, called Extremely Large Telescope or ELT, was proposed a few...

The International Coherent Amplification Network (ICAN) has discussed concepts of a novel laser system based on a massive array of fibre amplifiers for the final goal to achieve particle acceleration at highest efficiencies. The laser parameters of >10 J, <300 fs at repetition rates above 10 kHz require a fundamental new approach in order to overcome known limitations of todays Peta-Watt...

Probing the nature of the quantum vacuum is indispensable to resolve the crucial problems in contemporary physics; dark matter and dark energy in the universe. Probing the vacuum to date has been limited to either the macroscopic space-time via astronomical observations or microscopic space-time points at high-energy particle collisions. With high-intensity lasers, however, we anticipate to be...

iCAN project opens new and unmatched possibilities both for electron and ion acceleration. The availability of a huge number of coherent to each other laser pulses allows for efficient use of the laser field itself for electron acceleration. A periodic dielectric structure can be used at intensities of around 1012 W/cm2 and provide accelerating fields on the order of GV/m. Due to the...

Producing high peak and average power lasers with high efficiency, as proposed by the International Coherent Amplification Network (ICAN) group, will open a new era in particle accelerator physics and will allow us to construct the first high energy photon-photon collider (ggC). Among the various options for Higgs factories, a ggC has the distinct advantage of not requiring a positron source...

Beam optimization of laser-accelerated protons is a crucial point for the development of applications in various areas. Several directions need to be pursued, namely (i) optimization of the high-energy end of the spectrum e.g. for dense plasma radiography, (ii) optimization of the low-energy end of the spectrum e.g. for isochoric heating of matter, (iii) enhancement of laser-to-protons...

I will discussed the various techniques used to produce radioisotope for medical applications. The use of intense lasers require high average power that will become available with the ICAN concept. I will present the necessary laser parameters for an efficient generation of radio-isotopes with lasers.

The ICAN concept of coherent combination of femtosecond pulses at high energies presents new challenges on the optical amplifiers in terms of fidelity, reliability, efficiency, and cost. The more mature continuous-wave amplifiers for coherent combination, femtosecond amplifiers, high-power amplifier systems, and not least telecom amplifiers lay a very strong foundation for the ICAN...

The presentation will start with a brief review about the history and achievements of advanced rod-type rare earth doped fibers and their use in ultrafast fiber laser systems followed by an introduction to coherent addition of multiple individual emissions as a performance-scaling concept. To further enhance the performance towards multi-Joule pulse energy and towards Megawatt average power in...

The demand for a huge number (i.e. up to millions) of channels for a fiber laser based particle accelerator originates from the energy limitation of a single fiber emission rather than average-power capabilities of rare-earth-doped fibers. Therefore, it is possible to reduce the required number of channels by 2-3 orders of magnitude by operating the fiber amplifiers at a higher repetition rate...

Coherent Beam Combining allows overcoming the nonlinear and damage thresholds that limit the output power/energy of fiber amplifiers, thus enabling new applications as in the ICAN project. We will briefly review the main coherent beam combining techniques useful for ICAN with an insight into optical efficiency, requirements and cost.

The challenge of producing the next generation of particle accelerators, both for fundamental research, or for more applied tasks such as proton therapy or nuclear transmutation has been taken up by the high intensity laser community. To reach the ultrahigh peak power and high average power requirements of these applications, coherent beam combination of thousands of fiber amplifiers has to be...

The ICAN laser proposal aims for multi-100 kW of average power. Optical Components handling such power have to be identified in the future. In this contribution, the relevant components and their power handling is reviewed. Additionally, the physical background for thermal- and nonlinear limitations are given and strategies and perspectives of reducing these effects are discussed.
