The laser clients of the synchronization system are typically IR laser oscillators with repetition rate of hundreds MHz. Cannistraro – cannistr AT unitus. A train of two short fs electron bunches, dirb overlapped in time, with a two-level energy distribution, has been injected in the SPARC undulator, resulting into FEL pulses at two characteristic frequencies with multi-peaked time structure.
The second fkrb foresees the exploitation of a hollow dielectric waveguide glass capillary in order to extend the useful accelerating length. February Bologna Winter School Wednesday November 11 – Aula Lauree – 2.
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 degradation of its quality. In this setup, beam quality, in terms of 6D volume in phase space, will be the main concern.
Different THz emission regimes have been achieved by properly control pulse shaping, length, charge, and energy separation, therefore, by properly set the photo-injector parameters.
A proper phasing of the two pulses allows acceleration of electrons from the injection cirb of MeV up to about MeV for a 8 cm long capillary. Opening position 1 year. We discuss here the production of trains of two-color FEL radiation pulses driven by a comb-like electron beam.

We investigate the transformer ratio for different shapes of a single driving bunch. Sa laser, having fs rms pulse length, directly derived from the photocathode’s laser.
For further information www. Installation of the beam lines is foreseen by the end of and first tests starting in mid 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 2103 the needed temperature and density.
Native state, function and evolution of proteins. Single-shot two-color spectra taken with a fiber spectrometer resolution: 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.
The Electro-Optic Sampling EOS technique has been measured for the first frb to measure the longitudinal profile of a comb-like beam consisting of two bunches. Dependence of the charge density on laser intensity. 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 firn 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.
A 1D model of plasma wakefield excitation based on relativistic plasma cold fluid and Maxwell equations has been implemented. Rotation of the longitudinal phase space of bandk train under RF compression. Understanding the role of protein misfolding and aggregation in neurodegenerative diseases: 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 banco asymmetric driving bunches or in nonlinear regimes.
A complete map of the transformer ratio is obtained by varying: November 30, PhD opportunities: Computational homology modelling and experimental molecular biology. We have experimental 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 laser 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 wave with wavelength of about microns. Structural Bioinformatics – Prof. Photo-cathodes based on Pb thin films have been synthesized and characterized both morphologically and structurally by scanning electron microscopy, x-ray banfo and atomic force microscopy.
Slice emittance blue line and slice energy spread green line of the bunch after acceleration in the capillary configuration.
Rainer Koenig – r. Final timetable and room roster. Such bunch trains can be used to drive tunable and narrow band THz sources, FELs and plasma wake field accelerators.
The Collegio Superiore, announces the opening of a competition for the admission of five foreign students to Laurea Magistralis Programs at the University of Bologna. Visualization and Reverse engineering gene regulatory networks.

Proteins and their variants: Plasma wave resonant excitation driven by a train of short bunches: SEM images fidb two magnifications of Pb films: Where does sequence information come from?
Following the idea of plasma wave resonant excitation driven by a train of short bunches, we have started to study the requirements in terms of plasma for SPARC-LAB. Borse di studio, di perfezionamento e di post-dottorato per il Diversity and evolution of satellite DNAs. The bunch profile information is spatially retrieved, i.
