Employer: DESY (Deutsches Elektronensynchrotron), Hamburg, Germany

Type of position: PhD student / Postdoc

Duration: 2-3 years for Postdoc positions, 3 years for PhD positions

Anticipated start date: as soon as possible. The program is open all year long with no fixed application deadline.

Tasks and responsibilities:

  • Start-to-end simulations of a 5 GeV laser-driven plasma accelerator
  • Investigation of required improvement/optimization schemes for laser/plasma/beam with industrial quality as well as alternative or hybrid driver schemes
  • Development of use cases for particle physics/photon science/other fields
  • Design of user areas and studies of possible sites and costs

Applicants should have the following skills and qualifications:

  • Knowledge of basic electrodynamics or willingness to learn this
  • Experience in the construction and performance of precision experiments, in development and usage of computer programs for simulation of complex processes and possibly experience in accelerator construction and theory
  • Enthusiasm for research, for the invention of new technical solutions and for the construction of science machines is required and replaces missing expertise in accelerators
  • Good proficiency in English, the work will be performed in strong international collaboration with world-class research centers in the UK, Italy and the US
  • Postdoc positions require a PhD in physics or engineering
  • Doctoral students in the fields of physics or engineering may stay enrolled in their home university or enroll at the University of Hamburg or the Technical University Hamburg-Harburg (acceptance criteria must be met)

To apply, please submit the following documents to recruitmen(at)desy.de and ard(at)desy.de: letter of motivation (giving also type of position you apply for and your possible start date), Curriculum Vitae, copy of relevant degrees, publication list, names and contact information of two referees.

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

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.
