During run 126:
Beam was tuned to be centered and homogeneous in the target
efficiency and resolution of the CHIO was improved |

|
Gating on T1 to T4 and looking at the the CATS reconstruction on Target we confirm that;
- CATS is correlated to MUST
- Telescope Position matches CATS Position, so Telescope numerotation is correct and there is no inversion in CATS.

| There was a sudden increase of the temperature at 4pm. Fortunately the cell is still filled with liquid. |

Fixed, e755, Mon Jun 25 17:31:27 2018, daisuke, benoït, TARGET, Software, Cryo-LH2, RUN 127 (Still filled with liquid? test with Wien filter)
|
Beam spot is now too small to see the cell frames. Moved the beam spot down and up by using the Wien filter. It is not conclusive, but the gap between the
cell frame and the liquid surface is increasingly apart toward outside in X. It is possible that liquid filling the upper part of the cell has been evaporated.
Should carefully monitor the cell temperature and the beam image. |

|
After RUN 128, we entered D6 to add another deat time measuring pulses to U2M channel 9. This is supposed to correctly measure dead time both for MUVI1
in the master and MUVI2 in the slave. For detail, see page 85 in the logbook.

Previous run (RUN 131), MUST2 threshold was raised to 500 keV to see how the dead time (DESC/ORDD) is improved (found not effective). The threshold was
set back to 400 keV. |

|
Data analysis of run0128 (38Ca physics run). The multiplicity distribution of DSSD x-strips is shown in
Attachment 1. The second peak centered at around 128, which is the number of strips of one detector, corresponds
to events where beam-like heavy ions are hitting the detector.
