Development of Nb3Al Strand
|
|
In Magnet Technology Development Division, magnet with high current density has to be developed. Magnet should have sustainability of superconductivity at higher magnetic field. The superconductor for these applications requires high critical current densities Jc in high fields and high tolerance to mechanical stress and strain. The most promising conductor among the currently investigated ones is Nb3Al multifilamentary conductor

Hybrid DC Circuit Breaker for Quench Protection
|
|
Hybrid DC Circuit Breaker is basically a combination of mechanical switch and semiconductor, which is advancement over conventional mechanical breakers employed in the quench protection systems for superconducting magnet.
This hybrid switch ensures arc less current commutation into dump resistor during quench condition thus countering the major flaw in conventional breakers thus ensuring a reliable quench protection system. Presently Insulated gate bipolar transistor (IGBT) based hybrid dc circuit breaker is being investigated at IPR. This scheme has been validated through series of experiments till a current level of 1500A DC.
