What is Quench Parameter? & Where Does it Apply?

[axel1983]

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

The word "quench" (verb or noun) is now used to describe a section of superconducting current-carrying wire or cable that goes normal (loses its superconducting quality and becomes resistive). Initially it was used to describe the rapid cooling of materials such as red-hot steel in water to harden it.

thanks a lot!
so Quench Parameter in Nuclear physics means the decrease of peak curve?

I guess the term "quench" could also be applied to a reactor, when the control rods are pushed in and the reactor goes subcritical.

A reactor can also be shut down by an excess of certain elements like xenon gas, which has a large thermal neutron cross section. Xenon, which builds up in the fuel as it is consumed, is somtimes referrred to as a "poison" in reactors.
