Job description: Postdoc (f/m/d) Development of a radiation transport module in the particle-in-cell simulation PIConGPU
With cutting-edge research in the fields of ENERGY, HEALTH and MATTER, around 1,500 employees from more than 70 nations at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) are committed to mastering the great challenges facing society today.
The Institute of Radiation Physics conducts research for states of matter under extreme conditions and in very small dimensions.
The Department of Laser Particle Acceleration is looking for a Postdoc (f/m/d) Development of a radiation transport module in the particle-in-cell simulation PIConGPU.
Your tasks
# The goal of this work is to develop a fully functional radiation transport module in our plasma simulation code PIConGPU, based on a pilot implementation of an atomic rate solver for electron excitations and ionization.
# All relevant processes, including photonic excitations and ionization, recombination, Auger-cascades and transport shall be implemented and individually tested against analytic, numeric and experimental test cases.
# A significant part of the work will be testing and validation. Our group performs experiments at XFELs to study the heating, ionization and recombination processes in both high-intensity and high-energy laser-solid interactions. You will conceive and participate in experiments, as well as study existing data, to validate specific aspects of the simulation.
Your profile
# Completed PhD in the field of Physics or comparable Natural Sciences
# Experience in Plasma Physics
# Knowledge in simulations of many-body systems or plasmas
# Atomic physics and the interaction of radiation with atoms and ions are part of your area of expertise
# Working in an interdisciplinary team
# Management of connection to several external collaborators
# Ability to set individual goals, self-structure and fulfill milestones
# Parallel programming, ideally in C++ and with GPUs
# Knowledge with Python
# Excellent command of English (spoken and written)
Our offer
# A vibrant research community in an open, diverse and international work environment
# Scientific excellence and extensive professional networking opportunities
# Salary and social benefits in accordance with the collective agreement for the public sector (TVöD-Bund) including 30 days of paid holiday leave, company pension scheme (VBL)
# We support a good work-life balance with the possibility of part-time employment, mobile working and flexible working hours
# Numerous company health management offerings
# Employee discounts with well-known providers via the platform Corporate Benefits
# An employer subsidy for the "Deutschland-Ticket Jobticket"
We look forward to receiving your application documents (including cover letter, CV, diplomas/transcripts, etc.), which you can submit via our online-application-system.
This research center is part of the Helmholtz Association of German Research Centers. With more than 42,000 employees and an annual budget of over € 5 billion, the Helmholtz Association is Germany's largest scientific organisation.
Company
The Helmholtz Association contributes to solving major challenges to assure the future of our society. With more than 47.500 people on staff in 18 national Research Centers and an annual budget of more than 6 billion euros, the Helmholtz Association is Germany’s largest scientific organization. The name Helmholtz stands for concerted research, in which networks form the key principle behind inquiring thought and action.
The profile of the Helmholtz Association
The Helmholtz Association performs cutting-edge research which contributes substantially to solving the grand challenges of science, society and industry. To succeed in meeting these responsibilities, Helmholtz concentrates its work in six research fields: Energy, Earth and Environment, Health, Information, Matter, as well as Aeronautics, Space and Transport. Within each of these fields, research programs are developed by our scientists and regularly evaluated by renowned international experts. Their evaluation forms the basis for the program-oriented funding that is allocated to Helmholtz research. Within the six research fields, Helmholtz scientists cooperate with each other and with external partners – working across disciplinary, organizational and national borders.
Moreover, Helmholtz specializes in large-scale research infrastructures – from accelerator facilities, earth observation satellites, research ships to supercomputers. They form the basis for scientific advances in tackling global societal challenges. Managing national research infrastructure is part of the Helmholtz Association's mission.
Promoting young academics
Helmholtz scientists, a high-performance infrastructure and modern and efficient research management are the ingredients to the Helmholtz Association‘s success and global impact.
Promoting young researchers is a major priority for the Helmholtz Association. Its qualification schemes for young researchers are geared mainly towards PhD students, postdocs and young managers. The Helmholtz Association has set high standards for its talent management. Its strategy begins with targeted recruitment of highly qualified staff at all levels, followed by comprehensive support aimed at further developing their potential. Ensuring equal opportunities is an essential element in all talent management activities undertaken by the Helmholtz Association.
The Helmholtz Graduate Schools and Research Schools at almost all Helmholtz Centers provide doctoral students with the general and specific skills and training they need, as well as ample opportunity to network. The period following a doctorate is decisive in determining the direction and success of a scientific career. For this reason, we established Career Development Centers for postdoctoral researchers in the Helmholtz Centers. This equips young researchers with the skills they need to go on to head a Helmholtz Investigator Group, for example. As an Investigator Group leader, junior scientists can independently set up their own group to conduct research in their specialist field and acquire management skills.
Within its talent management strategy, the Helmholtz Association pays special attention to the increased recruitment of talented female scientists both from Germany and abroad. To this end, there are currently two funding programs supporting this policy: and Helmholtz Distinguished Professorship – Funding for the recruitment of leading international female scientists (W3) .
The increasing complexity of the content, structures and framework conditions of scientific work today requires researchers to organize their projects, their employees and, of course, themselves in a highly professional and effective way. In response to these demands, we have set up the Helmholtz Leadership Academy to provide leaders in science with professional management training. Furthermore, the Helmholtz network provides a platform for the alumni of the Helmholtz Leadership Academy to come together and share their experiences of leadership, career development and lifelong learning.
All of this combined makes the 18 Research Centers of the Helmholtz Association a highly attractive environment for talented researchers from all over the world.
