Run 11 started. D+ beam in the ring at 1.5 MeV.

No target at the moment. Valves to the interaction chamber will soon be opened.

Stats and histograms zero'd, monitoring code reset.

The overlaping test started by moving the beam only in the y axis.

02:00

Overlap test is over and was found that the optimal position for the horizontal axis is 8mm. Beam on target.

Observation of an increase the 1.5 MeV peak in the CARME monitoring code when overlap with the target is found. Attachment 4.

Drop in the beam lifetime is also observed when overlapped with the target.

CRYRING measurement cycle has been made shorter (from 5 to 3 repetitions) to match it with the decreased beam life time due to optimed overlap with target.
