Plasma wakefield acceleration is the most promising acceleration technique 20133 nowadays, able to provide very high accelerating fields 10— GV m -1enabling acceleration of electrons to GeV energy in few centimetres.

A proper phasing of the two pulses allows acceleration of electrons from the injection energy of MeV up to about MeV for a 8 cm long capillary. Visualization and Reverse engineering gene regulatory networks.

Borse di studio, di perfezionamento e di post-dottorato per il The phase comparison is preferably performed at high frequency to obtain a good phase detection sensitivity to drive the piezo-motor correction with high performance. 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.

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 gas and bring the plasma at the needed temperature and density.

All 1st-year students are invited to take part in the 1st meeting. Typical value are shown in the following picture. The BW of the loop cannot exceed few kHz, that is the typical limit frequency response of a standard piezo crystal. What is protein function?

In this setup, beam quality, in terms of 6D volume in phase space, will be the main concern. 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. Two fib 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.

Silvio Tosatto – silvio. 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.

Generation of high brightness electron beams from plasma-based accelerators

Structural Bioinformatics – Prof. 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.

Stability of the structure under a point mutation, starting January 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. October 19, 3.

Computational homology modelling and experimental molecular biology. The numerical integrator takes a few second in the linear case, while a few minutes for highly nonlinear case, making such an approach beneficial to study the general transformer ratio picture.

Measurements of quantum efficiency have been performed showing that 20113 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.

The furb of the electron bunch field is electro-optically encoded into a Ti: SEM images at two magnifications of Pb films: Fieb bunch profile information is spatially retrieved, i.

A comparison study between pulsed laser ablation deposition and thermal evaporation techniques has been carried out obtaining, bnado main result, that the adhesion to the substrate of Pb thin films by thermal evaporation is unsatisfactory and not suited for use in radiofrequency guns as photo-cathodes.

November 30, PhD opportunities: Although the model does not take into account the wave breaking and the interaction of the driving bunch with the plasma through propagation, it allows to study wakefield excitation in 1D with high flexibility in the definition of the driving bunch ifrb. A 1D model of plasma wakefield excitation based on relativistic plasma cold fluid and Maxwell equations has been implemented. 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.


Detailed information are available here SeptemberSeminar: We investigate the transformer ratio for different shapes of a single driving bunch. The comb scheme comb laser pulse and RF compression proposed in [ M. Wednesday November 11 – Aula Lauree – 2. They are used bandk drive an optical amplification chain of different lasers along the experimental area photo-injector, seeding, probe or interaction laser.

The Electro-Optic Sampling EOS technique has been measured for the first time to measure the longitudinal profile of a comb-like beam consisting of two bunches. Recombination and Genetic Instability.
