Noordwijk, Netherlands Sintesi dell’opportunità
The European Space Agency (ESA) in Noordwijk, Netherlands, invites applications for an Internal Research Fellow (PostDoc) in Space Environments and Effects. The role focuses on developing and validating ionising radiation transport models and software, primarily using Geant4 and GRAS, to assess radiation impacts on spacecraft and missions. Candidates should hold a PhD (or be near completion) in radiation, space physics, or related fields, with experience in Monte‑Carlo simulation and programming. The position offers collaboration across ESA departments and external partners, a multicultural work environment, and a focus on mitigation strategies for high‑energy radiation, solar particles, and other space hazards.

Descrizione del progetto
Location
ESTEC, Noordwijk, Netherlands
Our team and mission
The Space Environments and Effects Section supports the development of ESA missions and programmes by investigating the space environments within which they will operate, assessing likely effects and defining mitigation methods. Environments addressed include high-energy radiation from radiation belts; solar particle events and cosmic rays; plasmas encountered in planetary magnetospheres; the solar wind and artificially generated charges and fields on spacecraft; micro-meteoroids and non trackable debris; planetary and lunar dust; and planetary atmospheres. The Section also initiates and manages a wide range of related modelling, software and hardware R&D activities.

Field(s) of activity/research for the traineeship
A significant number of ESA missions fly in severe radiation environments that can have various effects on the spacecraft and their payload and instrumentation. Such effects include dose degradation in components, displace damage in solar cells, different types of single event effects in electronics, imaging instrument interference, internal charging and biological effects on astronauts. Detailed analyses of such effects, and possible ways to shield and mitigate against them, are typically conducted by using environmental prediction in combination with Monte Carlo radiation simulation toolkits such as Geant4 and its application, GRAS (Geant4 Radiation Analysis for Space).
ESA is a signatory member of the international Geant4 Collaboration together with CERN and a number of other institutes worldwide and has over the years contributed to a number of space-specific physics models and other software capabilities and applications to allow for accurate estimates of such radiation effects.
The goal of this Research Fellow position is to assess, test and further develop ionising radiation transport and effects analysis models and related software capabilities under the Geant4 and GRAS frameworks, together with the application of such developments to real-life cases of ESA spacecraft and missions. As part of this work in ESA's Space Environments and Effects Section, substantial collaboration with other parts of the Agency and with external partners in the radiation physics domain is expected.
