Dielectric diagnostics for charged particle beams


   PhD Opportunities

About the Project

For our location in Hamburg we are seeking: PhD student

Limited: 3 years | Starting date: earliest possible | ID: MDO006/2021 | Deadline: open | Part‑time

DESY, with its more than 2700 employees at its two locations in Hamburg and Zeuthen, is one of the world's leading research centres. Its research focuses on decoding the structure and function of matter, from the smallest particles of the universe to the building blocks of life. In this way, DESY contributes to solving the major questions and urgent challenges facing science, society and industry. With its ultramodern research infrastructure, its interdisciplinary research platforms and its international networks, DESY offers a highly attractive working environment in the fields of science, technology and administration as well as for the education of highly qualified young scientists.

Short electron bunches with durations in the femtosecond regime are sought after in a growing number of applications. For example, accelerator-driven X-ray sources like the EuXFEL require them to produce comparatively short light flashes. The current state-of-the-art diagnostic methods for such short bunches, based on radio-frequency deflecting structures, reach the required time resolution. However, they are high in cost and destructive for the electron bunches, preventing them to provide a live characterization of the bunches during operation.

DESY is developing novel charged particle beam diagnostics at the dedicated accelerator research and development facility ARES, and is looking for a PhD student to join this effort within the team running the radio frequency linear accelerator ARES. The main topic will be the development of a non-destructive dielectric structure-based charged particle beam diagnostic from simulation to device design to the proof-of-principle experiment at ARES. This will be complemented by operation and further development of the ARES linac. This research will be conducted in a very collaborative environment with SLAC, Stanford University, UCLA, FAU Erlangen and PSI already working together on experiments at the ARES linac.

About your role:

  • Simulation of charged particle beam interaction with dielectric micro-structures
  • Development of a prototype design
  • Planning and running of proof-of-principle experiment
  • Participation in the operation of ARES linac
  • Software development for machine control and data analysis
  • Participation in the on-going dielectric laser acceleration experiments

About You:

Look forward to a unique working environment on our international research campus. We attach particular importance to appreciative cooperation and the well-being of our DESY employees. Gender equality is an important aspect for us. To support work life balance we offer flexible working hours, variable part-time and job-sharing. You will benefit from our family-friendly and collegial atmosphere, our established health management and occupational pension provision. As a public employer, we offer you a secure workplace and facilitate your individual career with our compre­hensive training and development opportunities. Remuneration is according to the regulations of the TV-AVH.

About you:

  • Master's degree / Diplom in physics, electrical engineering or related field or equivalent qualification
  • Experience in electromagnetic field simulations
  • Knowledge of programming languages (esp. Python, C++)
  • Good understanding of electromagnetics, optics
  • Good communication skills in English
  • Working in a team
  • Experience with ultra-short infrared lasers is a plus
  • Experience with electron linacs is a plus
