12. WBS51 – Networking & Fiber Optic Infrastructure an infrastructure of fiber optic cables that connect the main experimental areas. All WBS can use this. conventional (tcp/ip) networking equipment such as switches and routers and wireless-access-points (WAP).

18. Control Room Facility

19. WBS57 – Control Room Facility A ‘normal’ Control Room Facility will not be supplied for CD-4/MIE. However, facilities such as lighting, power, fire suppression, HVAC, basic network communications, and telephones will be provided (not part of the NCSX workscope). The extent to which the Control Room Facility will be outfitted under GPP (as a general-use area) is unclear at this time. GPP planning is in-process. The Control Room will support PPPL physicists, engineers, and collaborators. The former PLT and PBX control rooms are approximately 2200 sq. ft. and will be used as the NCSX main control room. –For CD-4/MIE, WBS 5 will provide approximately six surplus office-style tables and chairs. The Computing Center will hold the bulk of networking equipment, NCSX server computers, and will be a fiber optic cable hub location for the WBS51 fiber optic cable infrastructure. Approximately 1200 sq. ft. of the former PLT DAS computer area will be used as the NCSX Computing Center.

20. WBS52 – Central Instrumentation and Controls Like NSTX, will use the EPICS software. Supervisory and integrated control of NCSX engineering subsystems and diagnostics. System provides data trending, alarm logging, operator displays, and integrated process control and monitoring functions for NCSX. NCSX Test Cell audio and video support.

23. WBS53 – Data Acquisition and Facility Computing Like NSTX, will use the MDSplus software. A data management infrastructure to catalog and manage experimental results for subsequent retrieval and analysis. Automated pre-shot device configuration and post-shot data acquisition. A pool of computers for data analysis. An Applications Program Interface (API) for common data analysis software, such as C, IDL, Matlab, LabVIEW, and EPICS.

26. WBS54 – Timing and Synchronization The Facility Timing and Synchronization System (T&S) will provide the hardware and software that facilitates the synchronization of hardware and equipment to the ‘microsecond’ degree, and computer programs on NCSX computers to the ‘seconds’ degree. The T&S requirements include: Local timing resolution of 100 nanoseconds, complex-wide synchronism < 10 microseconds. At least 64 hardware events. Timing signals will be provided that are low voltage, high speed, and electrically isolated, same as TFTR and NSTX. Generation_1 of the event decoder has been in use on NSTX for several years.

30. WBS55 – Real Time Plasma and Power Supply Control For CD-4/MIE, the control system must provide synchronized control signals for the (approx.) seven NCSX power supplies, and one gas injector. The control methodology will be open-loop; no feedback will be used to modify the computer’s outputs. WBS4 will specify the detailed requirements for power supply control. WBS2 will provide the detailed requirements for gas injection control. A standard PC/LabVIEW-based system architecture will be used to fulfill the WBS55 systems.

33. WBS56 – Central Safety and Interlock System The Central Safety Interlock System (CSIS) will provide system wide coordination of personnel and hardware interlocks. Each NCSX high-energy (or otherwise hazardous) subsystem will interface with the CSIS. The high-energy subsystem will be responsible for ensuring that the design of its (local) interlocks and safety features are adequate. The CSIS will provide a global E-Stop system, permitting individuals the ability to shutdown all hazardous equipment using E-Stop pushbuttons located throughout the NCSX complex. An access control system will be incorporated to control access to the Test Cell. Entry into these areas while “unsafe” will cause an automatic E-Stop. The CSIS will provide the NCSX Chief Operation Engineer (COE) with a centralized point of control to enable/disable, arm/disarm, and shutdown each NCSX high-energy (or otherwise hazardous) subsystem The CSIS M&S costs estimates are based on a cursory review of online pricing. A system configuration, parts list, and price quotes have not been developed.

37. Summary The similarity to NSTX’s central controls and computing and the availability of an experienced and diverse staff affords confidence that WBS5 will support the NCSX project. The remaining work has generally been identified. The effort that leads to the Final Design Reviews will produce the best estimate. The current contingency values (8-14%) were developed based upon the 2003 Preliminary Design Review’s values. Simultaneously supporting two ‘large’ machines is ‘new ground’ for the computer engineering staff. This situation presents a potential for impacting WBS5 schedule performance. The WBS5 workscope and cost have been substantially reduced since the CDR and PDR. Although the M&S costs could be further reduced, doing so would lessen the effectiveness of the staff which would tend to increase the labor costs.
