ProtoDUNE timing system
§ Some testing and characterisation
still to be performed
– Clock alignment using signal delay measurement – Clock characterisation § Production of more timing FMC – Will be used in DAQ kits

DUNE timing system requirements
§ 𝑃(1 𝑜𝑡) synchronisation within detector module § 𝑃(1 𝑛𝑡) synchronisation between detector modules → SNB trigger § 𝑃(1 𝜈𝑡) absolute accuracy → beam instrumentation sync § Fan-out timing signals to SP detector § Provide timing signal to DP detector White Rabbit network § Timestamp beam instrumentation signals on SPTS clock domain

Single Phase Timing System
SLIDE 5
DUNE timing system
§ GPS disciplined oscillator provides 10 MHz clock § Based around a master timing card hosted in a
𝜈TCA crate
§ Clock distributed to 12 fan-out cards using 𝜈TCA
backplane (dual-star topology)
§ Each fan-out card hosts 2 timing FMCs § Each FMC has four optical connectors § 12×2×4 = 96 optical outputs
– 1:8 optical splitters → 96×8 = 768 fibres
§ Develop prototype for ProtoDUNE run 2 (2021)
