[Esr-users] [New Logentry] Ramp Solenoid and Torus down to 0 A

[Probir Ghoshal]

I heard and was on call.
Denny and Nick was able to solve on temporary basis.
We need to have better solution (back up) to mitigate the risk in the future.

Denny - will be getting all together (buying components) as we have discussed. Also suggest some to evaluate the root cause why this failed. From the location and time, i presume it could be 1. rad damage 2. magnetic field.
But with magnetic field is highly unlikely and thus point me towards rad damage (may be i am wrong). I will suggest to please involve someone to access the rad level at that location if any...!
Please also talk to Dave K for his insight.

Regards

Probir

Thank you, Probir.

Yes, the run was good. We only had one major hiccup with the vacuum pump on the torus.

The next run is coming in June.

Very good Eugene.

Congratulations to the entire HALLB team for running the magnets successfully.
