7h50 : mise en chauffe en remote (frigo/chillers, modulateur, laser, cyclage)

Le cyclage de RI-C1/QP.08, RI-C1/QP.11 et RI-C2/QP.03 ne démarre pas tout seul (action nécessaire sur le boutton cyclage de l'élément).

Programme - Etude "IP dromadaire" ==> Scan pos horizontale FPC + phase 

Positions FENTES2/HEXA des 2 derniers shifts :
    Pos FENTE2 :    [H , V]  = [-3 , -10.20]
    Pos HEXA ech : [Tx , Ty] = [+79 , +31]

10h00 Beam is in the ring W/O RF, -120 pC, receipt saved: recipe_recipe_LI_TL_RI_all_20260217_09_44_16.txt on the base of reference for 50 MeV

recipe_recipe_LI_TL_straight_all_20260217_10_08_07.txt for the linac and the TL stright part

RF 100 kV phase -48.5 dg.

10h35 Standby, Changing the FPC controller

11h23 HV is on

11h40 RCDSon injection

11h59 RF gun phase 23 dg., Sect. Att. 2.39 dB, Phase 230 dg., Charges: (ICT) from -120 to 140 pc, (BPMs) -137, -137, 137, 137 pC

tunes: H 0.166, V 0.71

12h26 tunes: H 0.167, V 0.72. MRSV size is very sensetive to injection settings

At around 2:45 p.m., the power to the ring dipole went out.

16h42 RF 280 kV, phase -50 dg. Streak camera measurements for 100 kV and 280 kV

Orbit bump to change orbit tilt around IP

18h59 Stop ThomX
