Quench Dump Switch
The fast breaker that diverts magnet current into the dump resistor.
- Role
- Fast current diversion
A fast, reliable switch (breaker) opens on a quench signal to divert the coil current into the dump resistor within milliseconds. Its speed and reliability are central to magnet protection.
Common questions
What is the quench dump switch?
A fast breaker that opens on a quench signal to divert the coil current into the dump resistor within milliseconds. Its speed and reliability are central to magnet protection.
Is it a novel component?
No — high-current DC breakers are established technology. The engineering task is specifying and qualifying one to the magnets' current and reliability requirements.
