International audience; The instrumentation consists of two sets of Roman Pots installed respectively at 216 and 224m on both sides from the ATLAS IP to measure with precision the position (< 10 micrometers) and the timing (< 5ps) of the two back to back diffracted protons tracks. Each Roman Pot is equipped with several planes of Silicon strips detectors read out by a new version of the ATLAS Silicon tracker ABCD readout chip with a longer latency (6.4 microseconds) and fast OR outputs defining a track segment. Theses inputs are to be combined in time with the ATLAS level 1 trigger accept signal. In addition, these tracks are time filtered with a very fast timing detector (MCP-PMT) allowing to constraint further at the level 2 the position of the IP within a one millimetre precision., The description of the electronics and trigger system as well as the various technical issues associated with such challenging experiments (clocks, cabling,, time monitoring) will be presented.
