8h: mise en chauffe en remote (frigo/chillers, laser, modulateur, cyclage)

*** Programme : Mesure spectre et monochromateur à 61.5MeV (70MeV si le temps le permet)

61.5 MeV

09h35 HV is on
photocathod laser phase 62 dg.  The receipt 61p5MeV_20250703_12_56_55.txt loaded, going to 61.5 MeV (interlocks)
10h13 Beam is on TL/SST02. Sect. att. 0.992 dB, sect. phase 236 dg.
10h30 Aligned with QP1 - QP3, linac steerers: H [-0.2 -3.02], V [-2.55 3.22]
11h05 Beam is in the ring W/O RF with all ring correctors set to zero

RF 100 kV storage is good, but can't correct the orbit  at 61.5 MeV :  le faisceau est presque hors du tube ==> Try to go to 70 MeV

70 MeV

13h20 RF processing the section on 25 pps by increasing pulse length from 1 us to 3 us
13h56 70 MeV, Linac steerers H [0.21 -3.75], V [-2.84 3.33], sect. att 0.18, phase 255 dg. laser phase 56 dg. (On the base of 70_MeV_Vert_tune 0.66_good_20251212_13_56_38.txt)
16h17 recipe_recipe_LI_TL_RI_good_20260318_16_17_14.txt saved, screenshots, RF 100 kV, phase -36 dg., Freq. 500.031645 MHz

L'orbite n'est pas la meme que pour 50 MeV  ==> Checks spectres dromadaires a V+40 

X_fpc = -1.5 / -1.3 / -1.7 / -1.9 / -1.1  mais on a oublie d'ajuster la phase a chaque fois  .... meme phase (3.0 V) 
X_fpc = -0.9 / -0.7 / -0.4 / -0.2 / -0.5  en ajustant la phase a chaque fois
Cf les 2 screenshots "Spectre 70 MeV"

On se place a X_fpc = -1 mm (pas top mais dans l'urgence on se met la)

Fente2 centrees a l'oeil : [H , V] = [11 , -23]
Prise de spectres a +/- 10 en H et V  (a voir ce que ca donne offline)
