18:05 We believe we have an overlap between the beam and the target. Run 22 started.
CARME detectors in with the servo ONLY. Left arm pot 36.5 mm, right arm pot 37.7 mm
Target density apporx 2e11 atoms/cm2.
Shots into the rin partially stable (sometimes consecutive injections at high intensity, sometime apporx 1 in 4 fail rate).
We plan beam run overnight, remote shifters will check on the progress every 2 hours.

Everything ok. Temperatures and leakage current are okay.

FEE temperatures OK
System checks OK
ADC data items appears ok for all FEEs, except aoda09 shows rates of ~1kHz. Spectrum borwser shows this is from a single strip. Checl load aida09 several times but no change to the rate.
Leakage current appears fine. (Attachment 23)
Merger and tape server OK
Ring pressure appeared to have dropped and the target density had dropped to approx 5e10 at/cm2 range. Target nozzle moved 200 steps. Density back to 2.5e11 range and pressure is high -11 low -10 mbar range. <----- Operator mistake

Target density appears to have been very stable over the last few hours ~2e11 at/cm2. Ring pressure also appears stable.
FEE temperatures OK
System checks OK
ADC data items appears ok for all FEEs,Aida09 rate appears to be reduced again.
Leakage current appears fine.

I am not confident we are seeing significant Rutherford scattering accumalated so far.

Noticed operator mistake at 3 am. Ring pressure was very bad in YR08. Unlikely we had much beam since then. Moved nozzle to improve pressure.
See attach 38 & 39.
