Quench of a conventional 4.7T magnet.  Since it is unsafe to be inside the room during this quench, the video is taken from the outside and shows the helium vent pipe.  Thousands of liters of liquid helium are purged in a great cloud at significant cost to the user.

Intentional quench of an SSI 1.5T-720mm cryogen-free magnet.  The initiation of controlled quenches is a routine part of SSI’s magnet evaluation process and ensures product safety and durability under quench conditions, including those directed by the user.
