Could anybody tell me what is so called Quench Parameter ?
And where is that parameter applys into?
Thanks a lot!

The quench parameter is a measure of the ability of a material to withstand an electrical and magnetic field without losing its superconducting properties. It is a ratio of the critical current density to the critical magnetic field, and it is used to determine the stability of superconducting materials.
The quench parameter applies to superconducting materials, specifically in the field of superconducting magnets. It is important in the design and operation of these magnets, as a low quench parameter indicates a more stable material and a higher quench parameter can lead to the loss of superconductivity and potential damage to the magnet.
The quench parameter is affected by several factors, including the material composition, temperature, and magnetic field strength. Superconducting materials with higher critical current densities and lower critical magnetic fields will have a lower quench parameter, making them more stable. Additionally, a lower temperature can also decrease the quench parameter.
The quench parameter is typically measured by applying a magnetic field to a superconducting material and gradually increasing the current until the material loses its superconducting properties. This critical current density and magnetic field are then used to calculate the quench parameter.
The quench parameter is important in the design and operation of superconducting magnets. A low quench parameter indicates a more stable material, which is crucial for the safe and efficient operation of these magnets. It also helps in the selection of suitable materials for specific applications, as materials with a lower quench parameter are more desirable for high-performance superconducting magnets.
