4482-Principle of Protection of Katrin Coils
KATRIN is an experiment at KITto measure the mass of the electron neutrino
Needs line of small solenoids to guide electrons
Quenchpropagatesveryquicky and generates a voltage that open the diode.
Then the coildischargessafely on itself.
This system is intrinsically safe
It is safe if the coil by construction can supportthe generated hot spot.One can spread more the energy by triggeringthe quench-heaters of the long quenched coil.
Two-coil set up
If second coil does not quench
One can show that the temperature of a givenwireat time t, is a directlydependent of:
Called the currentload in MIITS
( In adiabatic conditions!)
( Also considered in adiabatic conditions!)
Two-coil set up - final
