The European Spallation Source (ESS) is a high current proton LINAC to be built in Lund, Sweden. The LINAC delivers 5 MW of power to the target at 2500 MeV, with a nominal current of 50 mA. The project entered Construction phase on January 1st 2013. In order to design, develop and deliver a reliable, well-performing and standardized control system for the ESS facility, the Integrated Control System (ICS) project has been established. The ICS project also entered Construction phase on January 1st. ICS consists of four distinct Core components (Physics, Software Services, Hardware and Protection) that make up the essence of the control system. Integration Support activities support the stakeholders and users, and the Control System Infrastructure provides the required underlying infrastructure for operating the control system and the facility. The current state of the control system project and key decisions are presented as well as immediate challenges and proposed solutions.

During the design and construction of an experimental physics facility (EPF), a heterogeneous set of engineering disciplines, methods, and tools is used, making subsequent exploitation of data difficult. In this paper, we describe a framework (DISCS) for building high-level applications for commissioning, operation, and maintenance of an EPF that provides programmatic as well as graphical interfaces to its data and services. DISCS is a collaborative effort of BNL, FRIB, Cosylab, IHEP, and ESS. It is comprised of a set of cooperating services and applications, and manages data such as machine configuration, lattice, measurements, alignment, cables, machine state, inventory, operations, calibration, and design parameters. The services/applications include Channel Finder, Logbook, Traveler, Unit Conversion, Online Model, and Save-Restore. Each component of the system has a database, an API, and a set of applications. The services are accessed through REST and EPICS V4. We also discuss the challenges to developing database services in an environment where requirements continue to evolve and developers are distributed among different laboratories with different technology platforms.
