| TUPDP028 | Challenges of the COSY Synchrotron Control System Upgrade to EPICS | 561 |
|
||
| The COSY (COoler SYncchrotron) at the Forschungszentrum Jülich is a hadron accelerator build in the early 90s, with work started in the late 80s. At this time the whole control system was based on a self-developed real-time operating system for Motorola m68k boards, utilizing, unusual for this time, IP-networks as transport layer. The GUI was completely based on Tcl/Tk. After 25 years of operation, in 2016, it was decided to upgrade the control system to EPICS and the GUI to CS-Studio, in order to e.g. allow a better automatization or automatized archiving of operational parameters. This was done together with Cosylab d.d. bit by bit while the synchrotron was in operation, and because of the complexity is still ongoing. The experiences of the stepwise upgrade process will be presented and a lessons learned will be emphasized. | ||

Unified Systems Engineering Methodology for the Design of ITER Diagnostic Systems | |
|
||
| To control and monitor the plasma, ITER will use a number of different diagnostic systems, each with its own operating principle, and composed of different components. The systems will go through several design stages, and a unified systems engineering methodology is needed that will generate comparable design outputs for validation, integration and assembly of the systems. However, having the same methodology for such different systems means that it has to be general enough, such that the requirements of different systems are covered, the challenge being to find a compromise between the high-level approach and the final usability of the system design. The methodology needs to be such that sufficient input is provided to the developers and engineers in the successive phases, in an effort to minimize the risks in the development and integration phases. With the goal of addressing these challenges, a common systems engineering methodology for the design of ITER diagnostic systems was derived; Cosylab tested and validated this methodology by applying it to several diagnostic systems, and also identified and implemented improvements and developments to this methodology; lessons learned and observations made in the process of applying this methodology will allow systems engineers to gain a deeper insight into the relationship between systems engineering, architecture and design, and project management, in the domain of fusion-specific developments. | ||
