Currently it is around 8e8.</p> <p>09:00</p> <p>Target density has been increased to the high -10, very low -11 region. We will keep this run going unless the density is increased further.</p> <p> </p> <p>10:21</p> <p>Beam energy = 3 MeV.</p> <p>Horizontal beam position = 4.0 mm, vertical beam position = 0.0 mm.</p> <p>Target density ~ 1e9 at/cm2 (no target, get lost quite quckly)</p> <p>Beam intensity at inj ~ 1.7e7</p> <p>Detectors are positioned IN. Left arm = 36.54, right arm = 64.60 mm</p> <p>Histograms and stats zero'd, monitoring code restarted.</p> <p>Beam in the ring ~ 6 minutes.</p> <p>Pressure in YR09 E target ~ 4.36e-11 mbar.</p> <p> </p> <p>Merger OK, Tape server OK</p> <p>ADC data item statistics looks as before. OK</p> <p>FEE temperatures look OK</p> <p>System checks OK</p> <p>Leakage current stable</p> <p> </p> <p>target density has been fluctuating between E9 to E12.

When a valve is closed, can be observed a dramatic change in the plot and one of the three green ligths of atps7vaccrz1 (0,2,4) is turned off. Nikos opened it, and now it seems stable again around 1e11.</p> <p> </p> <p>14:07</p> <p>Merger OK, Tape server OK</p> <p>ADC data item statistics looks as before.

Might as well get beam background</p></td> </tr> </tbody> </table> </p><p> </p>
