Preparations are underway to build the Electron Ion Collider (EIC) once Relativistic Heavy Ion Collider (RHIC) beam operations are end in 2025, providing an enhanced probe into the building blocks of nuclear physics for decades into the future. With commissioning of the new facility in mind, Accelerator Controls will require modernization in order to keep up with recent improvements in the field as well as to match the fundamental requirements of the accelerators that will be constructed. We will describe the status of the Controls System architecture that has been developed and prototyped for EIC, as well as plans for future work. Major influences on the requirements will be discussed, including EIC Common Platform applications as well as our expectation that we’ll need to support a hybrid environment covering both the proprietary RHIC Accelerator Device Object (ADO) environment as well as EPICS.

Brookhaven National Laboratory’s Collider-Accelerator Department houses over 550 Front-End Computers (FECs) of varying specifications and resource requirements. These FECs provide operations-critical functions to the complex, and uptime is a concern among the most resource constrained units. Asynchronous data delivery is widely used by applications to provide live feedback of current conditions but contributes significantly towards resource exhaustion of FECs. To provide a balance of performance and efficiency, the Reflective system has been developed to support unrestricted use of asynchronous data delivery with even the most resource constrained FECs in the complex. The Reflective system provides components which work in unison to offload responsibilities typically handled by core controls infrastructure to hosts with the resources necessary to handle heavier workloads. The Reflective system aims to be a drop-in component of the controls system, requiring few modifications and remaining completely transparent to users and applications alike.
