our pp laser experienced timing jumps by 18 ns today. this happened for the first time at ~7:30 in the morning without us noticing and a couple of more
times during the morning. we realized it at 15:30 due to the fact that the signal on our pulse arrival monitor (X-ray/laser cross correlator downstream
of the experiment) disappeared. we spent some time to investigate it, until we also see this jump in two different photodiodes different triggers (oscilloscope |

Today in the afternoon, SASE1 was tuned (a description of the activities in att 4). We now realize that this has in some form changed the SQS pulse parameters.
att 1 shows ion spectra recorded under nominally the same photon parameters before (run 177) and after (run 247)
it's also visible in the history of the SASE viewer that the behavior of the SASE3 pulse energy is different before and after 15:45, which |

Dear all,
Due to a probable issue at the SA1 Transmissive imager, the "OUT" and "YAG" position indication signals seems to be not responsive.
After the FXE team noticed that MODE S was interlocked, the root cause has been narrowed down to this component. Later, further investigation |

Issue with SA3 Gas attenuator (SA3_XTD10_GATT) - SOLVED
Dear all,
after the reported issue by SQS colleagues regarding the impossibility to inject Argon, and after a first remote evaluation, we (VAC) have entered
XTD10 to assess the status and verify the most probable working hypothesis: a manual valve in the supply line was closed (otherwise as expected). Joshua |
