10:30 Beam ON

Loading recipe: LI_TL_RI_good_20241114_15_27_46

11:30 RF section phase: 191 deg, Att=2.56dB

Start position feedbacks...

Beam seen in the LE (but very weak).

Recipe saved as TL_test_20241129_12_06_24

12:15 Access in Fosse nord for ALTO => 1h30 break.

13:45 Restart beam

Difficulty to tune...

15:12 Extraction at t=92.3

LIB.01 was at -7.48 moved to -4

15:41 Ext kicker very stable

Beam seen in EL/DG/BPM.01

Beam intensity on the BPM is varying with a long period. We can not identify the source of the variation.

Transmission is about 20% but most of the losses probably occur in the EL.

17:00 Beam OFF
