    keyword=Very large spikes in target vacuum

    A few minutes ago, we started seeing very large spikes in the target vacuum -- much larger than previously. Fig. 1 is zoomed out so you can see the scale of the spikes; Fig. 2 is zoomed in so you can see the gradually increasing trend of the baseline. Maximum value is 8x10^-4, but baseline is more or less steady at 1.6x10^-4
