OF INTEREST: Manufacturating for acceleration grid power supplies has started in India

​Manufacturing is underway in India for the acceleration grid power supplies that will be supplied to the SPIDER test bed in Italy as well as to ITER’s diagnostic neutral beam.

 
The technical specifications for both acceleration grid power supplies are similar (system rated for 96 kVDC, 75 A). The SPIDER test bed is designed to finalize the development of the ion sources required for the ITER neutral beam injectors and to test all essential aspects of the diagnostic neutral beam accelerator.
 
Following the Final Design Review held in August 2013 for the acceleration grid power supplies, a Manufacturing Readiness Review was conducted early this year at the Indian Domestic Agency with the participation of the ITER Organization and ECIL, the Indian manufacturer responsible for the fabrication of the system and its installation at the SPIDER test bed in Padua, Italy.
 
Major components of the acceleration grid power supplies—60 kW water-cooled switched power supply modules and 2.8 MVA oil-cooled multi-secondary transformers—are presently being inspected at intermediate stages and the factory acceptance test for the first batch is scheduled for the end of November 2014.
 
Discussions are also being held with local support agencies for SPIDER site works with coordination assistance from the Consorzio RFX team in Padua.
