“Generation of Femtosecond Electron Bunches”
High Energy (few MeV- few 10’s of MeV) femtosecond electron bunches are nowadays mandatory in several domains gathering Accelerator Physics and Laser-Matter interaction, as for instance Laser/Plasma Wakefield Acceleration, Free Electron Laser, Generation of Coherent Thz or Ultrashort X-rays light sources. A program, aiming at exploring the ways to produce such beams in a compact manner has been recently initiated in the Saclay/Orsay area, France. It involves several laboratories: CNRS/Laboratoire de l’Accelérateur Linéaire (LAL), CEA/Laboratoire d’Interaction-Dynamique-Laser (LIDyL), CNRS/Laboratoire de Physique des Gaz et des Plasmas (LPGP), and the Centre Laser de l’Université Paris Sud in Orsay (CLUPS).
This program is currently under implementation and first results are expected in winter 2016-2017. The primary goal in the first experiments of such a program is to obtain femtoseconds electron bunches from the PHIL 5-10 MeV RF-photoinjector platform, coupled with the 50 fs-long CPA-based Ti:Sa laser facility LASERIX, and to investigate their improved features in terms of brightness under different regimes, from classical photoemission to non-linear multiphoton emission.
In this experiment, the Postdoctoral fellow will contribute to the preparation of measurements, data taking, and to the data analysis. It will conclude about the quality of the obtained electron bunch (charge, longitudinal and transverse emittance). Such a program, mainly experimental, will be naturally supported by a deep theoretical and numerical analysis. Another component of this project is to contribute to the development of a more accurate temporal measurement of these short bunches. This can be achieved in particular by radio frequency structures. After a review of opportunities for both technical and budget issues, the post-doctoral fellow will propose the best solution for PHIL both from the point of view of staff availability, budget, and the possible implementation on the PHIL line.
The postdoctoral fellow will belong to the accelerator team (CNRS/LAL). He/she will have to propose and setting the strategy for fully characterizing and controlling the femtosecond electron bunches issued from the PHIL test line.
EXPECTED PROFILE
Applicants are expected to hold a PhD degree in physics or in a related field.
The candidate should have a strong attraction for experiments
An expertise in the dynamics of charged particle beams would be a significant advantage.
The eligible candidate should be able to communicate at a scientific level in English.
The postdoc is two years for an immediate startup in 2016.
The interested candidates should apply quickly.The applications (including a detailed CV, a cover letter, a list of coordinate of supervisor) are to be sent to :
