Postdoctoral position (f/m) in Beam Dynamics and Simulations - URGENT
Fellowship and Doctoral Program in Accelerator R&D​

The Physics Department of the University of Rome “Tor Vergata” is looking for candidates for a 3‐years Assistant Professor position.

The Project:
The Plasmar project is a collaboration between INFN, Sincrotrone Trieste, ENEA and University of Rome Tor Vergata which is positioned as a necessary bridge between the pioneering Plasma Wakefield Acceleration) and the reliable exploitation of new radiation sources. The goal of our project is to contribute to the research effort and development towards the creation of a new generation compact FEL source, driven by a plasma accelerator, through the development of fundamental accelerator components.


The Position:
The progress of extremely compact plasma accelerators requires the development of ancillary components needed to build up an accelerator, such as for example particle beam diagnostics. Conventional techniques cannot be directly used for the peculiar characteristics of the plasmaaccelerated beams. Therefore, new techniques must be study, designed and tested to allow the full
characterization of those beams. At the same time great attention will be devoted to the application of these bunches of charged or
neutral particles, produced and accelerated for example in the interaction of a high laser power with solid materials or with capillaries filled with a plasma.

Scientific objectives: Research and development of new diagnostic devices for beams produced by plasma acceleration. Applications of compact particle and radiation sources based on plasma acceleration.


Requirements:
PhD in accelerator physics or equivalent subject knowledge, skills and experience Skills in some of the following areas are desirable: plasma acceleration, electron beam diagnostics, high power laser.
Very good knowledge of English.


Duration:
The position is limited to 3 years.


Teaching commitment: The activity of teaching, of integrative teaching and of service to the students will be carried out within the Physics course, also through the development of exercises.


The candidate interested in such a position should contact: alessandro.cianchi@uniroma2.it

CEA is strongly involved in EuPRAXIA, especially in physics and simulation, as well as electron beam design and optimization. In order to optimize the various parameters of laser pulse and plasma and to characterize the electron beam properties, numerical simulations are performed by means of dedicated codes in laser plasma acceleration modeling, coupled to particle beam dynamics codes. The electrons must be transported from the source (external RF injector or plasma injector) to the plasma cell in which the electron beam will be accelerated. Manipulation of the beam is particularly challenging because it must be only a few femtoseconds long and a few micrometers large at the entrance of the plasma accelerating structure, while the expected energy spread and divergence at the exit must fit rather constraining user needs.


The post-doctoral position in Beam Dynamics opened at CEA is related to the beam studies in the frame of the European EuPRAXIA project and will focus on the optimization of the electron bunch at the entrance of the plasma structure, and at the transport line towards the users.


The selected candidate will be appointed for 24 months. The position is based at CEA-Saclay, France.
