Central Solenoid (CS) components have an abundance of technical challenges ranging from material science to component interfacing. In manufacturing, a CS module is subjected stringent high voltage insulation strength tests at multiple occasions. The engineering challenge where multitude quench detection wires need exit the bulk and materials boundary or compatibility become issue. assembly, each terminals jumped its respective feeder line via extension lead that manufactured with interfacing...
The ITER Central Solenoid (CS) will be realized by assembling a stack of six modules. Each module is solenoid consisting 40 pancakes wound with Nb <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> Sn Cable in Conduit Conductor (CICC). tests the second (CSM#2) were performed at General Atomics (GA) facility Poway (US). During test campaign, CS Module submitted to dumps transport current from different initial values (10, 15, 20, 25, 30, 35,...
General Atomics (GA) is currently under contract to fabricate the ITER Central Solenoid Modules (CSM). The managed by US at Oak Ridge National Laboratory, sponsorship of Department Energy Office Science. includes design and qualification manufacturing processes tooling necessary seven superconducting CSM (6 + 1 spare) that constitute Solenoid. modules will be produced delivered site during 2017-2019. GA has established a fabrication facility combines 1,500 m <sup...
General Atomics (GA) is fabricating seven ITER Central Solenoid Modules (CSM) for the Organization (IO). As part of fabrication process, all CSMs undergo factory acceptance testing (FAT) prior to shipment IO. The FAT includes charging modules 40 kA and performing fast discharges (7.3 second decay time constant) measure alternating current (AC) losses. These generate high voltages at electrical connections between CSM test facility. Due a discharge fault during 3 FAT, Paschenization methods...
The ITER Central Solenoid is under fabrication by the U.S. organization and its subcontractors. will supply seven modules to IO, six of which be assembled in a stack that forms Solenoid. first were built GA at their facility, went into high voltage testing, including Paschen testing vacuum, then they tested 4.5 K up 40 kA demonstrate compliance coil with requirements. In this article, we present Test Plan results central solenoid (CS) module's performance, especially full current. We...
The ITER Central Solenoid is under fabrication by the US organization and its subcontractors. will supply seven modules to IO, six of which be assembled in a stack that forms (CS). All CS were or tested at 40 kA Final Test facility General Atomics, Poway, CA. Testing included high voltage, as well Paschen testing vacuum global leak tests before after cooldown 4.5 K EM cycling kA. In paper we present results Module 4 performance, modifications test improve reliability instrumentation. We...
General Atomics (GA) is under contract to UT-Battelle c/o Oak Ridge National Laboratory for the fabrication of ITER Central Solenoid Modules (CSM). GA will provide seven modules Organization (IO), six which be assembled in a stack that forms Solenoid. All CSMs are required pass factory acceptance testing (FAT) at Atomics' Magnet Technology Center (MTC) test facility prior shipment IO. Currently, 1, 2, and 4 have completed FAT been delivered CSM5 has CSM3 repeat after resuming its campaign....
The ITER Central Solenoid (CS) is under fabrication by the US organization and its subcontractors. will supply seven modules to IO (International Organization), six of which be assembled in a stack that forms Solenoid. In operational scenario CS (CSM) experience very high voltages, especially during plasma initiation disruption. Also, there are significant induced voltages CSM due magnetic coupling with PF coils current. During initiating current, voltage on reaches up 11 kV. We need...
Two systems used in factory acceptance power testing of the ITER Central Solenoid Module (CSM) at General Atomics' Magnet Technologies Center are Alpha Scientific 50kA dc Power Supply (DCPS) and Siemens circuit breaker (DCB). Both were designed specifically for this application; capable charging CSM to safely discharging its stored energy, up 1GJ. Nominally DCPS DCB would have been fully commissioned after completion CSM1 testing. However, several issues occurred during first three test...
The uniqueness of the ITER fusion project drives purpose and scope here to fulfil (functional) Procurement Arrangement (PA) requirements for Central Solenoid (CS) Correction Coil (CC) magnets' electrical insulation [1-3]; as used undertaken covering high voltage testing operations magnet coil winding pack (WP) vacuum pressure (VPI) beam qualification, followed in 2016 by start magnets series production USA China [1, 2]. Useful be considered common state-of-the-art power components practices...
The ITER Central Solenoid (CS) modules are under fabrication by the US organization and its subcontractors. will supply seven to Organization (IO), six of which be assembled in a stack that forms Solenoid, last one being spare. first module, namely CSM 1 was manufactured General Atomics (GA) went through Factory Acceptance Tests (FAT) including high voltage testing, Paschen testing then cold test at 4.5 K up 40.0 kA order demonstrate compliance with coil performance requirements. paper...
The ITER Central Solenoid Modules (CSM) are being fabricated at General Atomics (GA) their Magnet Technologies Center in Poway, CA. Each of the seven modules will undergo final testing GA facility to demonstrate performance 48.5 kA, 11 T, and 4.5 K. In order perform tests on multiple modules, a demountable coaxial joint using indium wires was developed connect feeders. Two full scale joints were establish assembly technique preliminarily tested (up 3 kA) CSM qualification coil (Cu...
