Shift started at 18h

With the current injector settings, it was difficult to inject.  We loaded the settings from last Friday 30/09 (19-22-04).

Principal steps:

- Correction of the one quadrupole polarity this morning

-injection tuning, observation of Turn-by-Turn-X, Turn-by-Turn-Y and Sum

-quads focusing, defocusing +-.0.5%

-iterative manual adjustments of corrctors, DPI, Septum, Kicker

-orbit correction with open line model response matrix 

- several datasets taken for further postprocessing

Beam is stored !!!!! ~400 turns (limited by the Libera response)

Stored beam, visible  more than 300 turns,  signal decay as estimated  due to Libera cutoff filters. To store more, RF cavity should be used.

Stable closed orbit!

Important milestone is achieved.

No losses at scintillator/fiber except for the injection, see oscilloscope screenshot.

Current machine settings are stored in recipe_recipe_LI_TL_RI_20221003_20_24_01.txt

Orbit is stable for more than one hour. End of the shift.
