| The rate in the diamond was decreasing even if the rate in VAMOS was more or less constant. Now it seems stabilized. |

Attached a tentative time calibration for the square MG10_X from run 89 (to be checked!).
Even applying the calibration the spectrum E_TOF for MG10 (run 115) displays many structures. |

1. A monitor of the primary beam failed and the astreinte had to be call (PCP did it).
2. The H2O cold box went in default. The cold water for AGATA digitizer; vamos crates and CTA went up to 25 deg!

This search was triggered by our lack of seeing the 3958keV line at the expected level. 2689 keV line observed (runs 112,115,116) as 55-60 counts. Expected
yield in 3958 keV line based on 80:20 branching and 1.5:1.0 efficiency is 10 counts. We see (at most) 2 in the full photo-peak for this line. (Theses two
counts are also lower than expected by about 20 keV.)

Further to the previous post on gamma-ray lines, attached is Kanungo's paper on doppler-attenuation measurement of the 4033 line for lifetime measurement.
The lower-energy lines are, however, not included in the figures. |

|
goal: we want to check whether the yields of the 1297.7 keV (from 19Ne 1536, 3/2+, l=1 state) and 1340 keV (from 19Ne 1615, 3/2-, l=2 state) g-ray lines
is compatible with what we expect from x-sec calculations

|
The beam intensity decreased by half since 19h00 (600 in Vamos-or)due to the primary beam.
The operators are working on it since.
The intensity of 10^7 pps came back at 8 pm.
