A test facility (SPIDER) is foreseen to be built in Padova, Italy, in order to test and optimize the RF source of negative ions to be used in the ITER neutral beam injectors. In this contribution the Langmuir probe system designed for monitoring the region, where most of negative ions are expected to be produced, will be presented.
