[Dsg-hallb_magnets] [Revised Logentry] 1035 Amp Quench @ 16:15:42

[Brian Eng]

The attached text file is 12000 lines (why not 10000 since we're supposed to be sampling at 10 kHz?) x 44 entries (21 VT + current, for some reason each has the same timestamp).

I made an Excel file that doesn't have the duplicate timestamp columns, maybe that's easier to work with?



The VCL B plot makes me question if force synchronization really works as we're expecting it to, it sure looks like VT19 should line up with the rest?
