An FPGA-agnostic system for achieving picosecond-level phase determinism in timing distribution links for High Energy Physics experiments Open
Picosecond-level phase determinism in timing distribution systems is a requirement for future detectors in High Energy Physics. FPGA transceivers traditionally used to propagate timing signals generally do not meet this stringent requireme…

We describe a low-cost system designed to monitor wander in digital clocks with a precision of ≤ 1 ps. With this system we have shown that it is possible to track phase variations at the sub-picosecond level by adding noise to a reference …

We describe a low-cost system designed to monitor wander in digital clocks with a precision of $\le$ 1 ps. With this system we have shown that it is possible to track phase variations at the sub-picosecond level by adding noise to a refere…

The use of precision timing measurements will be a major tool at the HL-LHC, where it will be used to suppress pile-up and to search for long-lived particles. To control a reference clock with sub-picosecond accuracy, we have fabricated in…

Both the ATLAS and CMS Collaborations are planning to install new detectors designed to measure the time of arrival of particles produced at the CERN LHC to a precision of 30 ps or better. An essential component of any of these detectors i…
