Subject: Shift summary 
  • after alignment of the beam, the main topic of the day were flatfields for the AGIPD with various settings
  • corresponding darks have been taken in addition
  •  
  • it was challenging to generate proper flatfield intensities on the detector (1photon peak equally high as the 0photon peak) due to the low intensity (750uJ)
  • shift crew received a warning of the machine that using the required 352 pulses for longer time could lead to an overheating of components in the machine -> flatfields were generated by using 172 pulses and sticking them together by shifting the delay
