The IBEX Web Dashboard Jack Harper ISIS Experiment Controls EPICS Collaboration Meeting 2025
Experiment controls infrastructure EPICS 7 using CA, but serving PVA for most IOCs Eclipse RCP-based GUI, embedding CS-Studio Instrument servers are Windows IOCs and GUI Blockserver used for instrument-specific configuration CSS Eclipse RDB Archive Engine Read-only web dashboard for scientists, users, technicians Python-based scripting
Issues with the current web dashboard Maintenance Difficult to make PVs available UI Scaling (or lack of) Homegrown
What we settled on + https://github.com/ornl-epics/pvws + a very strict CA gateway

Conclusions Much simpler EPICS doing heavy lifting Modern CSS frameworks are great! PVWS has been stable Less moving parts Easy to add PVs just change gateway allowlist and frontend React keeps up with updates, but we haven t pushed it
