Sure, but why does that mean they must be losing the helium each time? I don't know anything about liquid helium and super conductors, but I know I don't need to replace my radiator fluid just because it cooled my engine.

Once used, it need to be cooled down to -252c to be reused. Not like a closed loop of oil

Alright, did some research, first off you're wrong about this being the reason even if this was a plausible reason. The real reason is the ash and heat divertors failed.

Second, you don't even need liquid helium for super conduction. Here's a few closed loop helium gas coolers that get to 10 kelvin. They need to be refilled on the scale of years, not from a single test.

I get you care deeply about helium loss but this is the last thing you should be accidentally spreading misinformation about. This process literally creates more helium then it uses.
