Information on the IPhT has been gathered into a Welcome Guide in French and in English, available on the IPhT website:
https://intranet.ipht.fr/Phocea/Vie_des_labos/Ast/ast_visu.php?id_ast=606
It includes information on administrative steps at arrival, campus organisation, facilities, academic travel, holidays, healthcare, social activities, and contacts.
To use the internal phone line of CEA, first dial the “2” and then the last four digits of your correspondents phone number. You can look these up in the IPhT annuaire.
