ALFA_CTPIN - a NBI hardware contribution to ATLAS

During Long Shutdown 1 of LHC the ATLAS Central Trigger Processor was upgraded. The upgrade included many significant improvements, but did also mean that the input-output time was increased. For the Roman Pot based detector ATLAS sub-detector ALFA the trigger signals for level 1 trigger already before Long Shutdown  1 arrived only just inside the possible latency. The ATLAS Central Trigger Processor upgrade therefore meant that without a new implementation gaining significant time, there would be no more level 1 triggering from ALFA. NBI committed to make the hardware part needed for a new integration. The talk will discuss the need of the new hardware, the conceptual design and the process ending with a final board taking data for ATLAS.
