2. NSTX Upgrade Project – Final Design Review June 22 - 24, 2011 MPTS CSU 2 The MPTS is a multi-time, multi-spatial point Thomson Scattering diagnostic for measuring the electron temperature and density profiles on the National Spherical Torus Experiment (NSTX) ST research facility. In 2009 the US Department of Energy approved the initiation of a project to upgrade the NSTX for approved performance. As a result, a new larger Center stack (CS) is being designed to provide enhanced operating capabilities. It is necessary to upgrade the MPTS to accommodate the new CS and provide MPTS coverage of NSTX Upgrade plasma operation. The vacuum boundaries closest to the vacuum vessel (VV) define the extent of this design review. Vacuum boundaries include torus interface valves, vacuum windows and blank covers. The Bay L port includes a number of diagnostics vacuum interfaces besides MPTS since they impact the port design but are not themselves part of this review. The VV interfaces cost is estimated at $967 K.The installation is to be completed in mid 2013. The cost and schedule details are covered in the project summary elsewhere. A successful PDR was conducted on 9 May 2011. The MPTS VV FDR is planned for late August 2011.

3. NSTX Upgrade Project – Final Design Review June 22 - 24, 2011 MPTS CSU 3 The ex vessel components which define the remainder of MPTS is a separate job. The work approval form has been submitted for management review and approval. The MPTS vacuum vessel modification at Bay L resulted in a design incorporating reinforcement of the VV at Bay JKLA, the MPTS FDR will include the optimization of the Bay L vacuum vessel reinforcement required to mitigate stresses from the upgrade enhanced operation. The optimization is proceeding in response to a chit from the PDR concerning the effect of the reinforcement on the Resistive Wall Mode (RWM) coils performance.
