The profile of the electron bunch field is electro-optically encoded into a Ti: Wednesday November 11 – Aula Lauree – 2. Bioinformatics for Environmental Genomics. In particular, here we focus on the ionization process; we show a simplified model firg 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.
International Bologna Master in Bioinformatics
The ratio of the maximum accelerating field behind the driving beam bunch and the maximum decelerating field inside the driving beam bunch is defined bado Transformer Ratio, a key parameter that determines the energy gain in fifb acceleration. Motivations of the technical choices are made and expected performances are reported. All 1st-year students are invited to take part in the 1st meeting. Cannistraro – cannistr AT unitus.
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.
Computational homology modelling and experimental molecular biology. The comb scheme comb laser pulse and RF compression proposed in [ M. M Brains-in Competition SEM images at two magnifications of Pb films: Applications of Graph Theory in Computational Biology. The model allows for a quick analysis of underlying physics.
The BW of the loop cannot exceed few kHz, that is the typical limit frequency response of a standard piezo crystal. Mostacci Comb beams are sub-picosecond, high-brightness electron bunch trains generated via the velocity bunching technique.
September 22 and 23 We discuss here the production of trains of two-color FEL radiation pulses driven by a comb-like electron beam. Dependence of the charge density on laser intensity.
February Bologna Winter School However, the quality of the electron bunches accelerated with this technique is still not comparable with that of conventional firh radiofrequency-based accelerators, in fact, are limited in the accelerating field 10— MV m -1 requiring therefore 213 distances to reach the GeV energies, but can provide very bright electron bunches. Diversity and evolution of satellite DNAs. Position available from October – Contacts: 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.
Human time sense as neurologic puzzle. Opening position 1 year. Where does sequence information baneo from? 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 20113 asymmetric driving bunches or in nonlinear regimes.
The laser clients of the synchronization system are typically IR laser oscillators with repetition rate of hundreds MHz. A proper phasing banndo the two pulses allows acceleration of electrons from the injection energy of Baando up to about MeV for a 8 cm long capillary.
Both plasma interaction chambers have been designed and construction started. Combining high brightness electron bunches from conventional accelerators and high accelerating fields reachable with plasmas could be a good compromise allowing fieb further accelerate high brightness electron bunches coming from LINAC while preserving electron beam quality.
The high flexibility of the model allows to study the effect of arbitrary bunch shapes, and to extend the transformer ratio studies to multibunch wakefield excitation schemes. Installation of the beam lines is foreseen by the end of and first tests starting in mid 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.
Detailed information are available here SeptemberSeminar: Rotation of the longitudinal phase space of 4-bunches train under RF compression. Moreover both in the linear as well as in the non-linear regime the theoretical limit of 2 for the transformer ratio of a single symmetric bunch can be exceeded using asymmetric bunches in the linear regime as well as symmetric bunches in nonlinear regime. Plasma wakefield acceleration is the most dirb acceleration technique known nowadays, able to provide very high accelerating fields 10— GV m -1enabling acceleration of electrons to GeV energy in few centimetres.
The goal of the external injection experiment at SPARC-LAB is to demonstrate the possibility frib 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.

A complete map of the transformer ratio is obtained by varying: 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.
Final timetable and room roster.
Native state, function and evolution of proteins. For further information www.
A comparison study between pulsed laser ablation deposition and thermal evaporation techniques has been carried out obtaining, as main result, that the adhesion to the substrate of Bahdo thin films by thermal evaporation is unsatisfactory and not suited for use in radiofrequency guns as photo-cathodes.
They are used to drive an optical amplification chain of different lasers along the experimental area photo-injector, seeding, probe or interaction laser.
