Speaker
Description
About the lecture:
Quench protection in fusion magnets is based on external energy extraction, due to the large stored energy. The external resistor system is arranged such as to adjust the maximum voltage to the ground to an acceptable level.
The quench propagation is slowed down due to the helium circulating in the cable in conduit, classically used in fusion magnets.
The quench detection is classically ensured by voltage detection in fusion magnets. The balance of the inductive voltage is more difficult to perform in comparison with Particle Physics or NMR magnets. This is due the simultaneous independent operation of several magnet systems together.
