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.

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.

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:


Postdoctoral position (f/m) in Beam Dynamics and Simulations 

The National Institute of Nuclear Physics and Particle Physics (IN2P3) of the National Center for Scientific Research (CNRS), the University Paris-Sud (UPS) and the University Paris-Diderot (UPD) invite applications for the position of Director of their future laboratory of physics in Orsay.

This laboratory will be a new joint research unit (UMR) to be created on January 1, 2020. It will result from the merger of five UMRs located on the Orsay university campus: the Center for Nuclear Science and Material Science (CSNSM), the Laboratory of Imaging and Modeling in Neurobiology and Oncology (IMNC), the Orsay Institute of Nuclear Physics (IPNO), the Linear Accelerator Laboratory (LAL) and the Laboratory of Theoretical Physics (LPT). The staff will be comprised of close to 600 permanent staff (370 engineers, technicians and administrative staff and 220 researchers and faculties) and about 250 non-permanent staff including 120 doctoral students.

The research activities of this laboratory will cover most of IN2P3's research areas. The teams are engaged in international projects in nuclear physics (such as experiments at the local ALTO platform and at GANIL), hadron physics, nuclear astrophysics and cosmochemistry, neutrino physics, as well as in large particle physics collaborations, such as at the LHC of CERN. They are also involved in high energy -ray astronomy, in the study of ultra-high-energy cosmic rays and gravitational waves, in the indirect and direct search for dark matter and in cosmology. The laboratory will host a large theoretical team involved in these research topics as well as mathematical physics and statistical physics. It will also have broad expertise in accelerator physics, both in research and development of new technologies and in the construction and implementation of large accelerator-based research infrastructure. In addition, its teams are involved in research activities in the field of nuclear energy, as well as health and environment related nuclear and particle physics.

The future director of the laboratory should have an outstanding scientific profile, experience in leadership positions in the domain of nuclear or particle physics or related fields, and a strong ambition for the laboratory. He or she should identify projects and activities, which should be primarily supported and developed in order to reinforce the position of the laboratory as a world-class laboratory. The start of the mandate is scheduled for January 1st, 2020. The term of office is five years.

Applications for the position should be sent to Lydia Roos ( before July 12. The applicant should join a curriculum vitae and a letter of motivation in which he or she is invited to express his or her vision of the laboratory in ten years from now, and lay out a plan of actions for the next five years. Candidates are invited to contact Lydia Roos who will provide them with documents elaborated during the preparation phases, which they are invited to use to prepare their project. An appreciation of the place and role of the laboratory in the national and international landscape is expected. It is further expected that the candidate will present his or her vision of:

  • The internal organization of the laboratory (management team, organization of research activities, construction and operation of particle detectors and accelerators platforms, data management, nuclear safety, …);
  • The administration of the laboratory, its human and financial resources, the relation to the funding organizations as well as the committees and councils of the laboratory;
  • The transforming of the laboratory work environment and HR accompanying measures;
  • The relations and the interactions with IN2P3 laboratories;
  • The interfaces and the collaborations with the regional scientific cluster

The applicants will be pre-selected for an interview with representatives of CNRS, UPS and UPD and an international expert, in the form of a twenty-minute presentation, followed by a discussion on the points mentioned above. The interviews will take place on July 15, 2019.​

Fellowship and Doctoral Program in Accelerator R&D​
Assistant Professor at University of Rome “Tor Vergata” 

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.
