MCIS TP1 is not running well. Needs investigation as soon as S1219 is completed.

Later... TP1 failed completely, and we are running without it. Starting late Saturday night, DRAGON began to observe a certain instability. We correlated it to MCIS:COL0, which skims total current continuously. It is pretty evident that the source is now toggling between two adjacent plasma modes, due to the somewhat higher vacuum at MCIS. Vacuum was something in the 7-8e-8 Torr range before, but has settled out at some 1.25e-7 Torr now. General consensus is to continue running like this, as it is a minor effect, as you can see below (blue trace). DMG
