Description

Beam profile monitoring is essential at every stage of an accelerator beamline, yet deploying dedicated diagnostic systems at each focal plane remains costly and time-consuming. This work demonstrates that a single, standardized software platform, combined with commodity hardware, can provide facility-wide beam profile monitoring with rapid scalability. The platform uses phosphor screens and industrial GigE cameras as a common hardware base. It has been deployed at two beamlines at the RAON heavy-ion accelerator: the KoBRA separator and the NDPS neutron source. Expanding to a new focal plane requires only mounting the hardware, registering the imaging geometry, and minimal software configuration. A single server instance operates all monitoring points simultaneously, preserving independent background models and measurement histories for each. Adaptive rebinning automatically adjusts the analysis granularity to match beam statistics, enabling stable profile measurements from primary beams to low-rate radioactive ion beams without manual intervention. Real-time results are accessible through a web interface and EPICS channel access from anywhere on the facility network. Position measurement performance and operational experience from both beamlines will be presented.
