These partners continue, with the CNRS and the École polytechnique, the development of RI APOLLON thanks to their scientific contribution. The operators CNRS and Ecole polytechnique are decision-makers, namely in communication.


RI APOLLON has a decision-making body (Board of Directors) and an executive body (the Direction). The users’ scientific community is present, with recognized experts, in three advisory committees:

Scientific Committee (SC). Composed of 6 members from French laboratories and 6 international members, the SC contributes to the RI APOLLON’s development of the scientifics et technicals orientation in an international context.
Technical Committee (TC).

The access to RI APOLLON’s beam time can be summarize as follows:

External time: on international Call Of Proposals (COF) – minimum 70% of access days open to users.
Temps expert: on COF reserved for parties (CNRS, École polytechnique) and partners (CEA, ENSTA, IOGS, SOLEIL) of the agreement – maximum 20% of access days open to users .
Development time: decided by RI APOLLON’s director, for example to honor a collaboration contract– maximum 10% of access days open to users.
This distribution of 70%, 20% et 10% can be reviewed annualy.
