| Title: | Quench onset and propagation in Cu-stabilized multifilament MgB2 conductors |
Authors: | Martínez, Elena CSIC; Muñoz, O. | Issue Date: | 11-Jan-2008 | Publisher: | Institute of Physics Publishing | Citation: | Superconductor Science and Technology 21: 025009 (2008) | Abstract: | The quench development of Cu-stabilized metal-sheathed MgB2 conductors has been analysed. Experimentally, energy pulses were deposited into the conductor by passing rectangular current pulses through a graphite-based epoxy heater. The temperature and the electric field profiles around the point heat disturbance that gives rise to a quench, as well as their time evolution, were measured from multiple voltage taps and thermocouples along the conductor. The measurements have been done at self-field under two different conditions: in vacuum and in Ne vapour. The experimental results are in qualitative agreement with the simulated ones, obtained by solving the one-dimensional heat balance equation of the system and using a finite n value characterizing the I–V curves (V∝In). The temperature and current dependences of the minimum quench energy and the quench propagation velocity are presented. Our results show that the nonlinear power-law current sharing in the normal zone had significant influence on the onset of the quench process and resulted in a marked deviation from the classical quench theory based on the critical state model. | Description: | 8 pages, 11 figures.-- et al. | Publisher version (URL): | http://dx.doi.org/10.1088/0953-2048/21/02/025009 | URI: | http://hdl.handle.net/10261/19397 | DOI: | 10.1088/0953-2048/21/02/025009 | ISSN: | 0953-2048 |
