Photo-cathodes based on Pb thin films have been synthesized and characterized both morphologically and structurally by scanning electron microscopy, x-ray diffractometry and atomic force microscopy. The goal of the external injection experiment at SPARC-LAB is to demonstrate the possibility to accelerate a high brightness electron beam, produced by a conventional accelerator, by exploiting the wakefields generated in an underdense plasma by a high power laser pulse, without degradating too much its emittance and energy spread.
We have bamdo investigated the emission of trains of SASE FEL radiation pulses with two-level energy spectra based on the FEL emission driven by a two-bunches electron beam with time and energy separation tunable with linac settings. The theoretical limit of two for the transformer ratio of a single, symmetric bunch in linear regimes has been verified, as well as the overcoming of this limit with asymmetric driving bunches or in nonlinear regimes.

It is found that the transformer ratio critically depends on rirb bunch shape and on the density ratio. Typical value are shown in the following picture. A 1D model of plasma wakefield excitation based on relativistic plasma cold fluid and Maxwell equations has been implemented. We discuss here bbando production of trains of two-color FEL radiation pulses driven by a comb-like electron beam. Although the model does not take into account the wave breaking and the interaction of the driving bunch with the plasma through firrb, it allows to study wakefield excitation in 1D with high flexibility in the definition of the driving bunch characteristics.
Silvio Tosatto – silvio. The bqndo pulse, 25 f s long, focused down to 65 microns into the capillary is injected ahead of the bunch, drives a weakly non-linear plasma fiirb with wavelength of about microns.
M Brains-in Competition Intensive numerical simulations will be performed to match the plasma flow characteristics to the particle acceleration scheme by improving the design of the plasma channel and by finding the suitable shape of the gas injection and extraction chambers, as well as the right pressure levels. Different THz ifrb regimes have been achieved by properly control pulse shaping, length, charge, and energy separation, therefore, by properly set the photo-injector parameters.
They are used to drive an optical amplification chain of different lasers along the experimental area photo-injector, seeding, probe or interaction laser. Dependence of the charge density on laser intensity. We show a simplified model to study the evolution of plasma induced by discharge, very useful to design the discharge circuit able to fully ionize the gas and bring the plasma at the needed temperature and density.
What is protein function? Simulations show a good result in that direction, although further optimization of the bunch generation and transport is still needed to reach optimal performances.
Institut Curie – Prof. The Collegio Superiore, announces the opening of a competition for the admission of five foreign students to Laurea Magistralis Programs banso the University of Bologna.

Structural Bioinformatics – Prof. This means that the RMO phase noise high frequency components cannot be followed and they should be very low to ensure a flrb time jitter between laser pulse and RF linac phase.
Where does bxndo information come from? Comb beams are sub-picosecond, high-brightness electron bunch trains generated via the velocity bunching technique. Combining high brightness electron bunches from conventional accelerators and high accelerating fields reachable with plasmas could be a good compromise allowing to further accelerate high brightness electron bunches coming from LINAC while preserving electron beam quality.
The profile of the electron bunch field is electro-optically encoded into a Ti: Two main schemes are currently investigated, ultra-short single bunch and multi-bunches comb beams, to generate high energy per pulse, broad and narrow spectral bandwidth THz radiation, respectively.

Opening position 1 year. Plasma wave resonant excitation driven by a train of short bunches: However, the quality of the electron bunches accelerated with this technique is still not comparable with that of conventional accelerators; radiofrequency-based accelerators, in fact, are limited in the accelerating field 10— MV m -1 requiring therefore kilometric distances to reach the GeV energies, but can provide very bright electron bunches.

Dottorato in fisica e chimica dei sistemi biologici. The BW of the loop cannot exceed few kHz, that is the typical limit frequency response of a standard piezo firn. SEM images at two magnifications of Pb films: Single-shot two-color spectra taken with a fiber spectrometer resolution: Visualization and Reverse engineering gene regulatory networks.
Plasma wakefield acceleration is the most promising acceleration technique known nowadays, able to provide very high accelerating fields 10— GV m -1enabling acceleration of electrons to Bnado energy in few centimetres. Following the idea of plasma wave resonant excitation driven bado a train of short bunches, we have started to study the requirements in terms of plasma for SPARC-LAB. The second one foresees the exploitation of a hollow dielectric waveguide glass capillary in order to extend the useful accelerating length.
Rotation of the longitudinal phase space of 4-bunches train under RF compression. The main aim of this experiment is to demonstrate that a high brightness electron beam can be accelerated by a plasma wave without any significant banso of its quality.
