NCSX

Primary Design Basis of WBS 5

• The NCSX Design Leverages the NSTX Technology and Experience Base and Provides a Low Risk - Cost Effective Implementation.– Commercial-Off-The-Shelf (COTS)

– Maximize Use of Open Source (Free) Software

– Just-In-Time Design & Purchase

– Steer Current NSTX Upgrades to Benefit NCSX• Network• CAMAC Replacement to CPCI & PCI• Synchronization System• Plasma Control (FIMM)

– CAMAC Instrumentation Will Not Be Used In Design

– Maximize Use of Experience Base at PPPL

Questions in NCSX WBS5 Design at CDR

• A non-CAMAC design for a facility Timing and Synchronization System

– As of the CDR:• Use the BNL/ORNL-Spallation_Neutron_Source (10

MHz) timing system

• Upgrade NSTX (TFTR) Design to Current Technology Base

• Migration from VMS based MDSplus to UNIX

WBS 54 Facility Timing and Synchronization

• Progress– A working prototype of a PCI based Timing And Synchronization

System will be deployed for the next NSTX run.

– Xilinx XC2S200, Spartan II, 200,000 logic & RAM gate FPGA

– CeSys PCI XC2S board ~$300

– Each board has 6 multi-function channels• Timing• Timed Gate• Time Interval Counter• Clock Generator• Timing & Sequencing

– A Signal Conditioning and Interface board has been designed and is being sent out for fabrication now.

NCSX

WBS 54 Facility Timing and Synchronization

• Clock application software is essentially complete.

• A standalone Windows GUI is being used for development now.

• A Windows DLL that will used by LabView and MDSplus is being tested.

WBS 53 Diagnostic Data Acquisition and Facility Computing

• VMS based MDSplus was proposed as the Data Acquisition and Data Management & Storage System for NCSX

• MDSplus services have now all been successfully ported to UNIX by the MIT developers– As of 2/24/03, all 5 CMOD CAMAC highways have been moved to

a LINUX MDSplus server: alcserv II

– MIT has 3 UNIX servers, 12 UNIX workstations, and 24 VMS workstations.

• 12 VMS workstations to be replaced with UNIX by end of FY03• MIT will be VMS free by end of FY04

NCSX

WBS 53 Diagnostic Data Acquisition and Facility Computing

• PPPL progress towards UNIX based MDSplus– UNIX based MDSplus has been used to store and serve TRANSP

data to local and offsite users for about a year. There are no performance issues with this port.

– NSTX Data acquisition team is now serving NSTX data trees with a test LINUX server.

– We will serve production NSTX data for the next NSTX run in October.

• PPPL will have a strong base of UNIX based MDSplus experience for NCSX design and startup requirements
