Data from current run - 35, with limited beam current and rates - see a recent post by Güray.

|
Since we were observing jumps of 16 ns in timings of all channels of whole boards, the assumption was that the
signals from logical FIFO arrive at different times to S-IN inputs to zero the TS counters.
6 originally placed cables of quite the same length were replaced with 6 cables of declared 3-ns length, same

41_ge_single_theta 101,117,143 looks ok. No peakdeformation of 511, other gammas FWHM around half of that of511 - ok
ch4 in total rate EAGLE_0 arouns 2.1 kHz - ok

Large beam intensity instabilities from 14:10 till 14:40. Beam intensity reduction requested. CH4 on Total rate EAGLE_0 returned to 1.9kHz. Intensity
became stable.

|
Beam stable, counting rate within limits, plunger distance within the given tollerance, gamma spectra ok, everything looks good but....
(yes there must be some "but"), refreshing of EAGLE_array_monitor.mat and NEDA_array_monitor.mat are out of sync. Mostly pure red colour
is dysplayed. Not very usefull and (I suppose) missleading information. |

Sun Mar 12 13:20:00 2023, EG, Problems, , , No Data

For a split second a red "NO DATA" notification appeared in the top right corner of Counting rates dashboard.
It looks like it did not change anything in data collection.

|
Using the data which we've sorted to date, I looked into the gamma-gamma coincidences and have identified a number of nuclei e.g. 50Cr, 52Mn,
55Fe which would be consistent with fusion-evaporation reactions involving the sulphur-32 projectiles and aluminium-27. Such reactions would yield a 59Cu
comound system and these channels would be populated as a result of the evaporation of a combination of alphas, protons and neutrons. |

Before this run TSs were moved on the LF level, so the BU has easier job to do and everything is more stable.
BU gate was changed from 1500 to 500 ns, this stay valid from now on.
