LHC Instability Trigger Distribution project (LIST)
The purpose of the LIST is to receive a trigger from a “cloud” of
devices and distribute it to all relevant devices to freeze their
acquisition buffers upon detection of the onset of an instability, with
low and fixed latency. The LIST will be also used to distribute triggers
between the early instability detectors and the actuators preventing
instability growth (e.g. the Transverse Damper - ADT).
The goal of the LIST project is to develop a network for transporting
trigger pulses between equipment involved in the LHC beam instability
diagnostics. The instability diagnostics system currently being designed
at CERN will provide wideband acquisition of beam pickup signals, so
that forming of the instabilities can be detected and studied offline.
