Pronunciation: /kwɛnt͡ʃ/
noun
Etymology: From Middle English quenchen, from Old English cwenċan, from Proto-Germanic *kwankijaną.
- The act of quenching something; the fact of being quenched.
“Then the MacManus [i.e. a ship] went down. The sudden quench of the white light was how I knew it.”
- The abnormal termination of operation of a superconducting magnet, occurring when part of the superconducting coil enters the normal (resistive) state.
“There are two main types of quenches, and both are triggered by the red button. A customer of ours actually pushed his once, out of curiosity. And no, he was not 7 years old. This button is primarily for safety purposes. In some rare cases, clear signage is ignored and metal objects like mop buckets, oxygen tanks, etc. get sucked into the bore of the MRI. These are very difficult to remove while the magnet is at field. And, if a patient is somehow pinned inside, an emergency push of the quench button can be a lifesaver. The button artificially heats the magnet and starts the chain reaction described above.”
- A rapid change of the parameters of a physical system.

“A suitable method to prepare a system out of equilibrium in order to study the ensuing dynamics is to quench the system, i.e., to change its parameters abruptly.”
- To rapidly terminate the operation of a superconducting electromagnet by causing part or all of the magnet's windings to enter the normal, resistive state.
“If someone is pinned against the MRI magnet by a ferromagnetic object, you may need to quench the magnet in order to free them.”
“These knobs are generally mounted behind a cover of some sort, to prevent someone from leaning up against them or putting a philodendron on top of them, because (1) that aforementioned geyser can represent thousands to tens of thousands of dollars of helium these days, and (2) quenching is Not Good for the integrity of the magnet, and in the worse^([sic]) case you might find yourself with a lot of high-quality scrap metal.”
