Summary
👤
Senior🎓
Top SchoolJeroen Hegeman is an applied physicist with 14+ years designing, building and operating timing, trigger and DAQ systems for major particle physics experiments, currently responsible for the 24/7 operation and Phase‑2 R&D of the CMS Trigger and Timing Control and Distribution System at CERN. His background spans hands-on detector work from D0 at Fermilab through CMS, with deep expertise in system-level integration, high-precision clock distribution and synchronisation for high-luminosity environments. He helped pioneer the pixel cluster counting method for CMS luminosity calibration and has led critical upgrade deliveries for the Phase‑1 TCDS. Comfortable at the intersection of hardware, firmware and software, he blends experimental rigor with operational leadership to keep large-scale detector systems running and evolving. An unusual strength is his track record of converting accelerator-driven requirements into practical timing solutions that scale to the High‑Luminosity LHC era.
