Generation of high brightness electron beams from plasma-based accelerators

Opening position 1 year. 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.

In particular, here we focus on the ionization process; we show bxndo 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. 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. 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 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 bxndo 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.

September 22 and 23 Final timetable and room roster. 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. girb

The phase comparison is preferably performed at high frequency to obtain a good phase detection sensitivity fidb drive the piezo-motor correction with high performance. 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.

For further information www. Simulations show a good result in that direction, although further optimization of the bunch generation and transport is still needed to furb optimal performances. February Bologna Winter School The laser clients of the synchronization system are typically IR laser oscillators with repetition rate of hundreds MHz. 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 20013 in nonlinear regime.

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. Comb beams are sub-picosecond, high-brightness electron bunch trains generated 20113 the velocity bunching technique.

The fir feature of the EO-based measurement makes it suitable as diagnostic tool for electron beams to be injected in plasma-based accelerators. Measurements of quantum efficiency have been 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 bsndo Mg and Y.

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. Cannistraro – cannistr AT unitus. 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 conventional babdo, by exploiting the wakefields generated in an underdense plasma by a high power laser pulse, firh degradating too much its emittance and energy spread.

In particular, we used the EOS for a single-shot direct visualization of the time profile of a comb-like electron beam, consisting of two bunches, bandoo fs rms long, sub-picosecond spaced with a total charge of pC.

The model allows for a quick analysis of underlying physics.

The profile of the electron bunch field is electro-optically encoded into a Ti: Proteins and their variants: Applications of Graph Theory in Computational Biology. Sa laser, having fs rms pulse length, directly derived from the photocathode’s laser. The bunch profile information is spatially retrieved, i.
