    keyword=Target vacuum briefly spiked above 10^-3

    The baseline target vacuum is still low (1.7 x 10^-4) but we have seen our first spike across the red-alarm threshold of 10^-3. (See Fig. 1) The vacuum readout reached 2.5x10^-3. It seems unphysical for the vacuum to return to its lower level so quickly.
