- Measured the speckle patterns using EPIX detector to estimate the beamsize focused down by 1D lens (Row 13).
- Heat load test to NFL #18 with 50 bunches.
- Measured the speckle patterns with 2D focusing lens to estimate the beamsize. wire edge scan? |

Day shift 28.02
Got the beam, aligned it up to the TCC, mirrors in 3 mrad configuration, checked positions for the CRLs. Optimised
beam at the HAPG. Beam stability was fine, energy up to 1,5 mJ at 8.2 keV, and up to 1 mJ at 9.1 keV (used for the spectrometer calibration). |

Beam delivery SASE 8,25 keV, 1300 µJ. Intensity stable,
but beam jittery in horizontal.
PRC (Dommach) did a ZZ around 13:00 and switched off coolling of M1 in XD1, but no effect on beam jitter. |

The intensity of the Seeding decreesed from 850 uJ to 550 uJ during the time between 20:00 and 02:00.
The Spectral purity also got worst, the beam in HIREX looks to have more SASE shoulders.
Between 18 and 20 we show a prossible transiant signal, PPL, of the lower branch. But a problem with the monochromator in the MID opt Hutch trigger |

Update of the damage tests at SQS.
Yesterday (15.04) SQS staff created a focused beam on our sample using a small YAG fragment we have placed on the holder.
Due to the unusual position, the beam is full of aberrations but it looked small enough for our purpose. Estimattion of the size is difficult |
