Abstract This report presents the conceptual design of a new European research infrastructure EuPRAXIA. The concept has been established over last four years in unique collaboration 41 laboratories within Horizon 2020 study funded by Union. EuPRAXIA is first project that develops dedicated particle accelerator based on novel plasma acceleration concepts and laser technology. It focuses development electron accelerators underlying technologies, their user communities, exploitation existing...
The Hamiltonian picture of the free-electron laser (FEL) is reexamined and multielectron effects are accounted for. conditions under which multieleetron effect can be neglected made precise (low-gain regime) and, in this connection, strong signal analysis Stanford experiment carried out.
We present the experimental demonstration of a new scheme for generation ultrashort pulse trains based on free-electron-laser (FEL) emission from multipeaked electron energy distribution. Two beamlets with difference larger than FEL parameter ρ have been generated by illuminating cathode two ps-spaced laser pulses, followed rotation longitudinal phase space velocity bunching in linac. The resulting self-amplified spontaneous radiation, measured through frequency-resolved optical gating...
On the wake of results obtained so far at SPARC_LAB test-facility Laboratori Nazionali di Frascati (Italy), we are currently investigating possibility to design and build a new multi-disciplinary user-facility, equipped with soft X-ray Free Electron Laser (FEL) driven by ∼1 GeV high brightness linac based on plasma accelerator modules. This study is performed in synergy EuPRAXIA study. In this paper report about recent progresses going facility.
Abstract CompactLight is a Design Study funded by the European Union under Horizon 2020 research and innovation funding programme, with Grant Agreement No. 777431. was conducted an International Collaboration of 23 international laboratories academic institutions, three private companies, five third parties. The project, which started in January 2018 duration 48 months, aimed to design innovative, compact, cost-effective hard X-ray FEL facility complemented soft source pave road for future...
The theory of free-electron lasers is extended to include the new coupling between an electron beam and optical wave propagating at angle \ensuremath{\vartheta} in arbitrary harmonic. allows laser be tuned a wider range wavelengths effects emittance beam. formulation results terms constants means that existing knowledge high gain, low weak fields, strong short pulses can immediately generalized off-axis propagation
Impaired platelet aggregation, normal shape change, and agglutination ATP secretion thromboxane synthesis in response to high concentrations of thrombin or arachidonic acid were found a patient with multiple myeloma hemorrhagic tendency. The purified IgG1 kappa its F(ab1)2 fragments induced similar changes when added vitro platelet-rich plasma from subjects. In addition, the paraprotein inhibited adhesion glass microbeads, fibrin clot retraction, binding radiolabeled fibrinogen von...
SPARC (acronym of ``Sorgente Pulsata ed Amplificata di Radiazione Coerente'', i.e. Pulsed and Amplified Source Coherent Radiation) is a single pass free-electron laser designed to obtain high gain amplification at radiation wavelength 500 nm. Self-amplified spontaneous emission has been observed driving the amplifier with high-brightness beam linac. We report measurements energy, spectra, exponential gain. Experimental results are compared simulations from several numerical codes.
We study the possibility of producing x-gamma rays with orbital angular momentum by means inverse Compton backscattering between a high brightness electron beam and twisted laser pulse. use classical electrodynamics retarded fields for evaluating radiation connecting it to that primary then propose dimensioning linearly polarized x-ray source momentum, starting from parameters operating Thomson setups.
The authors derive, by a biorthonormal state approach, the analogy of Berry's phase factor for open, non-conservative systems, both adiabatic and non-adiabatic evolution. In latter case, (non-unitary) evolution operator method is exploited. An application given to optical supermode propagation in free-electron laser.
In this paper we discuss in detail the dynamics of a two-state system ruled by non-Hermitian Hamiltonian. The relevance results to multiphoton ionization is also discussed and comparison earlier works presented.
Following a recent suggestion that binomial states exist in the quantized radiation field [ D. Stoles B. E. A. Saleh M. Teich , Opt. Acta32, 345 ( 1985)], we discuss simple physical model leads to probability distribution. We also point out relation between and generalized SU2 coherent states.
A preliminary comparison of the fundamental characteristics undulator and \ifmmode \check{C}\else \v{C}\fi{}erenkov free-electron lasers is presented. It assumed that both devices are operating in Compton regime they driven by a short-pulse relativistic electron beam.
