PRC was informed by MID at 8h50 about a new appeared limiation to about 60 pulses / train (MID operated previously at 120 pulses/train).
It turned out that this limitation came from the protection of the SA2_XTD1_ATT attenuator, in partiicular the Si attenuator.
MID had not noticed this before probably due to the fact that after bringing back A12 online, there was a bit higher pulse energy for MID, and MID changed the attenuation settings.

MID could continue working with the full required 120 pulses / train by inserting more diamond attenuators in XTD1 instead of Silicon and using additional attenuators downstream.
