The laser starts at 93 KW.

This morning I operated the laser locked with the RF for 1h30 without any delock. All the machine was switch off.

All the system was very stable. Sometimes the 20 Hz perturbation was visible but no delocking.

In the afternoon I switched ON just the kikers and septum (with the Kikers delay of not giving perturbation for the synchro -8.561) and I do the same thing => The situation is exactely the same, all the system is very stable (but 20 Hz perturbations). NO deloking during 1h.

I change the delay between Kikers to -7.561 => exactely the same situation, all is very stable!!!!

In 3h of synchronized operation, NO delock at all with or without Kikers!!!

Conclusion no effect at all when juste pulsed element are switched ON.
