AB  - The Trigger Synchronization and Distribution System (TSDS) is a core part of the LHC Beam Dump System (LBDS). It comprises redundant Re-Trigger Lines (RTLs) that allow fast re-triggering of all high-voltage pulsed generators in case one self-triggers, resulting in a so-called asynchronous dump. For reliability reasons, the TSDS relies on many RTL redundant trigger sources that do not participate directly to the execution of a normal dump. After every dump, signals propagating on the RTLs are analyzed by Post Operation Check (POC) systems, to validate the correct performance and synchronization of all redundant triggers. The LBDS operated reliably since the start-up of LHC in 2008, but during the Run 2 of the LHC, new failure modes were identified that could incur damage for the beam dump block. In order to correct these failure modes, an upgrade of the TSDS is realized during the LS2. This paper reviews the experience gained with the LBDS during Run 2 of the LHC operation and describes the new architecture of the TSDS being implemented. Measurements and simulations of signals propagating on the RTL are presented, and the analysis performed by the POC systems are explained.
