Which risk increases for a supercooled MRI magnet when a quench causes a rapid temperature rise?

💡 Explanation

During a quench, stored magnetic energy converts to heat raising coil temperature rapidly; thermal stress exceeds cryostat material strength since these are designed for uniformity maintaining low levels. Therefore cryostat failure leading to vacuum loss predominates, rather than just electrical damage, field change or gas venting that are separate lower energy processes.
