Weekly ~TUES ETM charge measurements taken

Since the PSL was being worked on this morning, I took the opportunity to take the ETM charge measurements so that we don't have to take up time tomorrow.  The coherence data looks good, however NDS is whining about something and won't let me produce the long trend.  Show me the money!

Soooo, TBC...

 

(Note, I had to restart the measurements a few times this morning since the ISIs kept tripping unexpectedly with expected SEI work.)

NDS likes me more than Betsy. 

Conclusion: We can wait another week or so before flipping the biases again. ETMY is close to needing it than ETMX, but ETMY has one quadrant that's got ~20V more negative charge than the rest, so we'll let it accumulate more positive ions and flip them both at the same time again.
