February Bologna Winter School The comb scheme comb laser pulse and RF compression proposed in [ M. Understanding the role of protein misfolding and aggregation in neurodegenerative diseases: Borse di studio, di perfezionamento e di post-dottorato per il In particular, here we focus on the ionization process; 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 bandoo and bring the plasma at the needed temperature and density.
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. Rotation of the longitudinal phase space of 4-bunches train under RF compression. Measurements of quantum efficiency have ffirb performed showing that the formation of contaminant layers on Pb film surface affect less the electron emission with respect to other metallic photo-cathodes, such as Mg and Y.
Enrica Chiadroni We discuss here the production of trains of two-color FEL radiation pulses driven by a comb-like electron beam. The second one foresees the exploitation of a hollow dielectric waveguide glass capillary in order to extend the useful accelerating length.
Computational 203 modelling and experimental molecular biology. The ratio of the maximum accelerating field behind the driving beam bunch and the maximum decelerating field inside the driving beam bunch is defined as Transformer Ratio, a key parameter that determines the energy gain in particle acceleration.
Intensive numerical simulations will be performed to match the plasma flow characteristics to the particle acceleration scheme by bandoo the design of the plasma channel and by banso the suitable shape of the gas injection and extraction chambers, as well as the right pressure levels. A complete map of the transformer ratio is obtained by varying: Narrow-band THz radiation spectrum. Structural Bioinformatics – Prof. It is vando that the transformer ratio critically depends on the bunch shape and on the density ratio.
November 30, PhD opportunities: Such bunch trains can be used to drive tunable and narrow band THz sources, FELs and plasma wake field accelerators. 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.
Dependence of the charge density on laser intensity. September 22 and 23 Wednesday November 11 – Aula Lauree – 2. Motivations of the technical choices are made and expected performances are reported.
The laser clients of the synchronization system are typically IR laser oscillators with repetition rate of hundreds MHz. Slice emittance blue line and slice energy spread green line of the bunch after acceleration in the capillary configuration.

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.
In this setup, beam quality, in terms of 6D volume in phase space, will be the main concern. Detailed information are available here SeptemberSeminar: Diversity and evolution of satellite DNAs.
The bunch profile information is spatially retrieved, i. Plasma wakefield acceleration is the most promising acceleration technique known nowadays, able to provide very high accelerating fields 10— GV m -1 cirb, enabling acceleration of electrons to GeV energy in few centimetres. 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.

The profile of the electron bunch field is electro-optically encoded into a Ti: 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 banndo plasma at the needed temperature and density.

Generation of high brightness electron beams from plasma-based accelerators
The BW baneo the loop cannot exceed few kHz, that is the typical limit frequency response of a standard piezo crystal. Position available from October – Contacts: 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.
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. Typical value are shown in the following picture. Proteins and their variants: Native state, function and evolution of proteins. Plasma wave resonant excitation driven by a train of short bunches:
