background


Arose from the ECSS Spacecraft charging standard


Formal standards are legal documents


There are other
de
-
facto

standards (e.g. NASA handbooks)


There are many important effects that do not lead to
requirements


As well as requirements, there is a need for guidance


on how to avoid plasma
-
induced hazards.


what the requirements mean in common situations


what codes are available


what test facilities there are

aims


To bring together, from open literature


guidelines and requirements


equations


data


tabular information and graphs


To promote the use and sharing of resources in Europe.


Links to simulation resources


Links to testing facilities
