Order-of-magnitude estimate of the target thickness.
We have about 5000 counts of 40Ca(p,d)39Ca(g.s.) in an angular range of 10-30 degrees.

|
Here is the temperature log when we evaporate the liquid H2 by heater.
The black line is what we call sensor A, which we monitor usually, and the red line is sensor B, which is the closest sensor to the target window. |
|
Fixed, e755, Sat Jun 23 22:03:17 2018, takeshi, TARGET, Hardware, , temperasure log of the target
|
I would report the temperature log of the liquid hydrogen target.
We consider it was liquid during the beam time up to now by the beam profile data on the target. |

|
9H10: D5 stopped at 9H10. We asked for the beam.
9H48: Still no beam. There is a problem with the beam current limits set in the accelerator. They have to change it from 40 nAe between CO1 and CSS1 |

Fixed, e755, Sun Jun 24 12:10:35 2018, takeshi, TARGET, Hardware, , target temperature during warming up
|
I would share the temperature log of the target cell during warming it up.
The thick line is the heat shield and the thin line is the cell.
The heat shield may takes 2 hours to reach 200 K and 6 hours for 270K.

Fixed, e755, Sun Jun 24 13:20:51 2018, takeshi, TARGET, Hardware, N/A, start target cooling
|
We started cooling the target cell at 13h03.
It would take 4 - 5 hours to cooling the cell enough low for liquifying hydrogen.

Fixed, e755, Sun Jun 24 13:25:30 2018, Fred, valérian, daisuke, DAQ, Software, N/A, Scalers to be recorded
|
The U2M scaler data cannot be recorded to the data in the current version of Narval. So there were no scaler data during the measurement of 40Ca.
To resolve the situation, we added register parameters for specified channels of U2M. This allows us to record the counts of a given channel at each event. |

|
It was found that the energy threshold of the strips was as high as 1 MeV. This threshold setting was chosen for the calibration and was never set back
to the nominal threshold (0.4 MeV) for experiments.
