LIST is a trigger distribution system based on White Rabbit. It can receive a trigger from a “cloud” of devices and distribute it to all relevant devices to for example freeze their acquisition buffers. The latency between reception and transmission of a trigger is done with a low and notably fixed latency, with an accuracy of better than 1 ns. The hardware of the LIST nodes is based on the SVEC FMC carrier equipped with a FMC TDC mezzanine and a Fine Delay mezzanine. More info at the Wiki page
