TID effects imply that one incident irradiation causes the ionizing of matter and it appears charge in places where it should not. TNID effects are motivated by the displacement of the atoms of the crystalline lattice from their balance sites.
The radiation analysis is an essential document for the revision and approval of the components used within space equipment. This document includes in a single place all the information (data, assumptions and methods) and the results obtained when analyzing the radiation effects in the components used.
For a better understanding, the information is split into 3 points that represent the different radiation mechanisms which affect an electronic component, giving a brief introduction of each as well as presenting a summary table of technologies and effects.
Propose a DD test standard
• Should be available by the end of the year after ESA and Components
Technology Board (CTB)/Radiation Working group (RWG) comments
• Goal of this presentation
⇒ Not a draft of the future guidelines, but:
• Remind the physical processes responsible of the displacement damages
• Remind the electrical effects
• List the main parameters that should be taken into account
The different DD level may be obtained by different particles.
Proton is preferred. The energy of proton should be selected based on the proton energy spectrum inside of the spacecraft.
Neutron may give underestimate test results.
TID and DDD should be tested on the same group samples.
The new CERN High energy AcceleRator Mixed Field facility (CHARM) allows to test several single components, as well as more complex devices, at different locations, characterized by particle spectra representative of the high- and low-altitude atmospheric, particle accelerator and ground environments.
A modular architecture specifically designed for integrating technology demonstrators and test applications in a fast-to-orbit cycle allows any interested team to prepare its payload for flight into orbit in less than 1 year.
