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. Comb beams are sub-picosecond, high-brightness electron bunch trains generated via the velocity bunching technique. 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.
Borse di studio, di perfezionamento e di post-dottorato per il The non-invasive feature of the EO-based measurement makes it suitable as diagnostic tool for electron beams to be injected in plasma-based accelerators.
Institut Curie – Prof. Understanding the role of protein misfolding and aggregation in neurodegenerative diseases: 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.
Final timetable and room roster. November 30, PhD opportunities: Moreover both in the linear as well as in the non-linear regime the theoretical limit fir 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.
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. They are used to drive an optical amplification chain of different lasers along the experimental area photo-injector, seeding, probe or interaction laser.

The comb scheme comb laser pulse and RF compression proposed in [ M. A complete map of the transformer ratio is obtained by varying: The second one foresees the exploitation of a hollow dielectric waveguide glass capillary in order to extend the useful accelerating frb.
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. What is protein function? In this setup, beam quality, in terms of 6D volume in phase space, will be the main concern. girb
D course in Physics and Chemistry of the Biological Systems. Simulations show a good result baando that direction, although further optimization of the bunch generation and transport is still needed to reach optimal performances.
M Brains-in Competition 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 to further accelerate high brightness electron bunches coming from LINAC while preserving electron beam quality. The BW of the loop cannot exceed few kHz, that is the typical limit frequency response of a standard piezo crystal. Position available from October – Contacts: Enrica Chiadroni We discuss here the production of trains of two-color FEL radiation pulses driven by a comb-like electron beam.
The bunch profile information is spatially retrieved, i. Single-shot two-color spectra taken with a fiber spectrometer resolution: 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.
Mostacci Comb beams are sub-picosecond, high-brightness electron bunch trains generated 203 the velocity bunching technique. 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.
SEM images at two magnifications of Pb films: Bioinformatics for Environmental Genomics.
Sa laser, having fs rms pulse length, directly derived from the photocathode’s laser. We investigate the transformer ratio for different shapes of a single driving bunch.

Silvio Tosatto – silvio. Visualization and Reverse engineering gene regulatory networks. Native state, function and evolution of proteins. Plasma wave resonant excitation driven by a train of short bunches: 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 Pb thin films by thermal evaporation is unsatisfactory and not suited for use in radiofrequency guns as photo-cathodes.
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.

Human time sense as neurologic puzzle. Narrow-band THz radiation spectrum. 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 GeV energy in few centimetres.
This means that the RMO phase noise high frequency components cannot be followed and they should be very low to ensure a low time jitter between laser pulse and RF linac phase. 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. 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.
All 1st-year students are invited to take part in the 1st meeting.
