Phillip, Wilfried, Max | Detectors | PMT Threshold | Since we have ions in the ring now, we looked
at the PMT thresholds and the widths. In
order to do so we looked at the Raw Signal |

Kristian, Simon, Ken, Ragan | Detectors | Changed PMT North | We did not see any signal at PMT North which
was the narrowband PMT. Changed it to the
old solar blind PMT. Now we see the resonance. |
