This entry is a followup to: 374263
keyword=[target] polarization, last 16 hoursA follow-up to halog 374263, which showed the target polarization
snapshot from the target gui for the last hour. Here I show it from
the last 16 hours, using data the TO has recorded.
Some of the fluctations are caused by beam trips (when beam goes
away the polarization increases).
From a crude fit to a hypothesis N = N0 e^{-t/tau}, I get a
pretty decent lifetime tau = 211 +/- 48 hours. Seems high,
but as you can see the polarization is pretty stable.
