Fixede755 Mon Jun 25 10:42:47 2018 daisukeTARGETSoftwareCryo-emptyRUN 106 (38Ca with empty target) S/N
p, d, t ratio of events from the target frame and from the target aperture (covered by Havar 6.5 micron and Mylar 2 micron)

R(d/p) = 0.3 (frame) 0.14 (target)
R(t/p) = 0.1 (frame) 0.07 (target)

The target cell produce less deuterons and tritons compared to the target frame.

The target cell also produce more particles within one event (or the multiplicity is higher).

Test for CAVIAR and CHIO:

Fixede755 Mon Jun 25 17:23:49 2018 Cherry Mx TeamCATSGeneralCryo-LH2Confirmation of CATS reconsctruction
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.

In attached picture you can see CATS position on target gated by:
- Red: T1
- Green: T2
- Violet: T3
- Noir: T4

There was a sudden increase of the temperature at 4pm. Fortunately the cell is still filled with liquid.
Fixede755 Mon Jun 25 17:31:27 2018 daisuke, benoïtTARGETSoftwareCryo-LH2RUN 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.

Fixede755 Mon Jun 25 20:01:07 2018 olivier, daisukeDAQHardwareN/AAnother deat time scaler
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.

The new dead time scaler counts at nearly the same rate as the originial dead time scaler. We could not see a meaningful difference.

Fixede755 Mon Jun 25 20:51:28 2018 daisuke, benoîtRUNGeneralCryo-LH2RUN 132
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.
