  • Date posted: 13 Apr 2021
  • Job type: Research facilities
  • Discipline: Accelerators, neutron & light sources 

Remuneration Group 13
Limited: three years

ID: APDO002/2021 
Deadline: open
Full time

DESY, with its 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.

The Photo lnjector Test Facility PITZ in Zeuthen (near Berlin) is one of the leading international groups in developments on modern photo injectors and their applications. Current R&D goals of PITZ include improving electron source brightness beyond state of the art for X-ray Free-Electron Lasers as well as applications of high brightness beams e.g. for FLASH radiation therapy R&D. FLASH radiation therapy (FLASH RT) involves treatments delivered by ultra-short bunches, and is a new and exciting possibility for cancer treatment. The PITZ accelerator is the perfect test facility for this new technique as it can deliver full treatment doses within a 1 ms bunch train. The detectors and methods established for dosimetry of conventional radiotherapy are not suitable for FLASH RT. The student will develop suitable detection and dosimetry methods, making use of the detector expertise developed for particle, astroparticle and accelerator physics applications at DESY Zeuthen in cooperation with national and international partners.

About the role

  • Simulate beam interactions using software packages such as GEANT.
  • Prototype and test several sensors for dosimetry, including CMOS imaging sensors (CIS).
  • Implement the sensors and readout in PITZ and test them with the unique beam properties available.
  • Optimise beam dynamics and test with phantoms to optimise the delivered dose.
  • Analyze experimental data and compare with simulation results.
  • Participate in shift operation for accelerator R&D at PITZ.

Good reasons to join

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. You will benefit from our family-friendly and collegial atmosphere, our established health management and occupational pension provision.
