[Dsg-hallb_magnets] [New Logentry] Follow-up Re: Torus MPS Faults

[Brian Eng]

I suspect there's still more in there; Probir and I left the Hall after the damaged component was located since it requires DC Power to do work in the supply and no attempt was made to really clean it out at the time. The supply should probably be given a once over once their work is done.

I'm not sure what the best procedure to clean it out would be. Vacuum? Compressed air? A combination of the two?

Another question is the braided copper jumpers themselves: there's definitely some fraying/knicks in at least one of them, but they're pretty minor/small from what I could see from the side I was on.

Assuming DC Power isn't actively working in the supply I'll go take some pictures so people will have a better idea what we're talking about.
