Goal: Vertical orbit and angle at the IP with I3 and I4 X-ray signals

8h55 Switch ON the modulator and all the machine

Camera SST2 : impossible de changer le temps d'expo    and SST3 not started

• Phase max Q = 333° with Q = 130 pC
• Phase Sec : 203°  and Att = 2.46 dB
• Aligned quads

With the previously saved receipt, the injection and charge of the stored beam was quite bad. We tried several receipts. We tried to tune the ring till ~16h.

The FPC was operated in synchronous mode with the power twice less as typical value.

The TL transport was different from previously used. We should try to keep the same orbit in the TL for reproducibility. 

The FPC scan showed the two peaks structure => to be understood.

Then, we re-loaded the lattice from folder Reference (changed the laser position @photocathode). With the energy-phase adjustments we arrived to the resonable conditions. The FPC scan is attached.

Both I3 and I4 were recorded/displayed during the shift. In this configuraiton, the X-ray signal was mainly maximized and I3 ~7k-8k pA (I4~ a few hundreds of pA).

The vertical orbit was modifief to have zero angle at the IP. See the plot attached. 

In this configuraiton, the X-ray signal was almost equally shared between I3 and I4 ~ 1k pA.

A proper conditions and FoM should be defined for further optimization procedures.
