<p>Run 11 started. D+ beam in the ring at 1.5 MeV.</p>
<p>No target at the moment. Valves to the interaction chamber will soon be opened.</p>
<p>Stats and histograms zero'd, monitoring code reset.</p>
<p>All checks and temps OK</p>
<p>Leakage currents OK</p>

<p>Currently no beam -> operators are optimizing the intensity of the beam</p>
<p>Optimizing target density as well</p>

<p>The overlaping test started by moving the beam only in the y axis.</p>
<p> </p>
<p>02:00</p>
<p>Overlap test is over and was found that the optimal position for the horizontal axis is 8mm. Beam on target.</p>
<p>Observation of an increase the 1.5 MeV peak in the CARME monitoring code when overlap with the target is found. Attachment 4.</p>
<p>Drop in the beam lifetime is also observed when overlapped with the target.</p>
<p>System OK</p>

<p>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.</p>
