In space radiation environment (similarly to other radiation environments), electronic devices undergo radiation damage induced by both cumulative and single event effects, i.e.,

  • single event effects (SEE) - due to a highly ionizing dose deposition caused by a single high energy particle occurring in a sensitive region of a device - can occur at any time and with short time response;
  • total ionizing dose (TID) effects - due to the accumulation of ionizing dose deposition over a long time - are a long term effects and uniformly affect all devices;
  • displacement damage (TNID) effects – due to the accumulation of crystal lattice defects over a long time – are long term effects and uniformly affect all devices

At national level a certain number of industrial and institutional/research assets and centers in the field of EEE need to be coordinated, supported and represented at international level.

Italy has a long experience in the field of electronics devices design, manufacturing and utilization for various market sectors and in particular for Space. For instance, in the last years some project have been implemented in the field of GaAs/GaN EEE for consolidating the presence of the National GaN supply chain in the european context, thus achieving the role of second european source.

In the above context, the core elements of the supply chain are the availability of dedicated infrastructures like foundries, design centers, testing facilities and research centers  and, finally, irradiation facilities.

Furthermore, it is worth to remark that the knowledge of space radiation environment, in general, is a driving element for:

  • focusing the investigation of radiation damage,
  • developing treatment/transport/simulation tools, and modelling particle fluxes and their transport to predict the expected operating conditions in space ratiation environment,
  • evaluating radiation impact on devices and their qualification, in view of their operation in space for both orbital and deep space missions.

ASIF agreement was established based on the consolidated concept that the development of future generation of EEE components is or is expected to be a key strategic area of interest for future investments.

 

ASIF program, as formulated by ASI, aims to establish an interactive coordinated set of the irradiation facilities, throughout the national territory, serving the national and international space communities. In addition, the project will allow programmes dedicated to extend the knowledge of the space radiation environment in view of orbital and deep space missions.

The main objectives are:

  • to grow the sensibility of national entities for the needs regarding space radiation qualification,
  • to make available, for national and international entities, a coordinated set of irradiation facilities with a recognized standard within ESA – ESCC framework.

To achieve these goals, ASI will act also towards other Space Organizations, interfacing with ESA.
In the initial phase, this process was involving selected INFN and ENEA facilities, but could be extended to other national facilities and companies operating in the sector; in the second stage an interactive portal/gateway will allow institutional, industrial and research users to benefit from irradiation services (like beam availability, TID and TNID dose estimates, dosimetric measurements and others) of elementary charged and neutral particles (electrons, protons, ions, neutrons and, finally, photons).
At first, the program envisages the standardization of the operative procedures, the definition of procedures for access to the use of the beams and the experimentation, the qualification and validation of processes and test procedures, taking into account i) European reference standards (ESCC / ECSS), ii) certifications of the test results, iii) launch of experimental research projects and technological developments in cooperation with users.

The ASIF project derives from the synergy between several institutional bodies, engaged with technologies and research activities related to effects of the radiation environment on the survival in the space and space hardware/assets, which are relevant to scientific and industrial space community.
The Italian irradiation infrastructure are a primary asset in the European panorama, in many ways unique. A structured exploitation of space research is foreseen to encourage:

  • the increasing of knowledge about human and hardware behavior in hostile environments,
  • the transfer of knowledge from the world of research on elementary particles and particle detectors to industry and scientific space community, with undeniable competitive returns in both industry and space research.

Within ASIF, dedicated irradiation facilities should be operating on standardized or intercompared protocols, and supported by appropriate dosimetry/measured fluences,since it is a key element for space qualification.
Furthermore, additional and correlated actions are required with respect to the:

  • understanding of physical damage mechanisms,
  • technological developments within the framework of space qualification,
  • modelling of space radiation enviroment transport-codes, modelling of particle fluxes and their transport within the heliosphere and magnetosphere, etc.,
  • accessibility to models and test facilities opened to (national and international) manufacturers,
  • growing of the designing and testing capabilities of national entities.
