How to come at Saclay

Be careful, the IRAMIS institute has two main sites:
-The IRAMIS divisions of SPAM, SPCSI, SIS2M, LLB are located inside the center of CEA-Saclay. (enter by the North Door 'porte nord')

- The IRAMIS divisions of SPEC are at l’Orme des Merisiers, also on the plateau but at a 3 km distance from the CEA center entrance.

and other divisions of IRAMIS are not at Saclay:

  • The IRAMIS divisions of LSI are at Ecole Polytechnique
  • The IRAMIS division of CIMAP are NOT at Saclay plateau but at CAEN...
