LIST is a general purpose trigger distribution system based on White Rabbit.* 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 distribution system can receive a trigger from a “cloud” of devices and distribute it to all relevant devices to for example freeze their acquisition buffers.
The hardware of the LIST nodes is based on the SVEC FMC carrier equipped with a FMC TDC mezzanine and a Fine Delay mezzanine.
The gateware of it is based on a 2-core Mock Turtle.

The first application of the LIST project is to provide a network for transporting trigger pulses between equipment involved in the LHC beam instability diagnostics.
