Subject: Shift summary 

beam parameters: 18 keV, 1 pulse on demand, 400 uJ

achieved:

  • VISAR calibrations
  • timing between X-rays, VISAR laser and DIPOLE laser
  • main shots with DIPOLE energies up to 35 J, 10 ns flat top -> shock wave compression experiments on user targets

night shift changed the phase plate to 250 um, re-aligned everything and continued with user programme succesfully

issues:

  • cryostat for the 100J is icing and needs to be defrosted which takes about 1 hour. The frequency of this happening is increasing - Over the last 24 hours it happened 3 times
  • slowness of controls - especially Karabo playground MDLs
  • slowness of DAMNIT and extraction of data tiff files
  • ADQ412 (HED_EXP_IC2/ADC/1) stops randomly acquisition on its own

X-ray beam delivery relatively stable, could make use of bit higher pulse energy. Mirror feedbacks work fine
