In case of a patient emergency, the system will ramp-down immediately after pushing the Emergency Ramp Down Unit button (ERDU). It will take < 3 days to be back in operation. In case an object is stuck in the bore (injector, cleaning tool, etc.), it will take about 1 hour to ramp-down the magnet from the service environment on the operator console. It will take < 1 day to be back in operation. In the cooling system, all helium moves to gas state and remains contained in the fully sealed cooling system. If Helium gets warmer, the cryo-compressor will cool down the magnet to <4K.
