3 Research with Photons at DESY
Three generations of X-ray sources in one place: DORIS III 2nd generation, 5 GeV machine till 22th of October PETRA III 3rd generation, 6 GeV machine FLASH 4th generation, VUV and soft X-ray range European XFEL 4th generation, hard X-ray range starting in

Extreme Conditions Beamline (ECB) P02.2 at the Hard X-Ray Diffraction Beamlines for Time Resolved Studies P02 fixed energies: 25.6, 42.7, 60.0 keV focus (FWHM) at 42.7 keV: Kirkpatrick-Baez mirrors 1.5 x 1.5 µm or Compact Refractive Lenses 4 x 8 µm sample stack with 100 nm precision PerkinElmer XRD 1621 detectors MarIP imaging plate Pilatus 1M detector (pool) gas membrane (not for all types of cells) online ruby pressure at both tables LH (left) GP (right) X-rays Laser heating table General purpose table W. Morgenroth, Uni Frankfurt

8 W. Morgenroth, Uni Frankfurt
Laser heating table Observation path: Ag coated glassy carbon mirrors geoHEAT 60_NIR objectives Prosilica cameras directly inspecting the sample, highly sensitive to see the fluorescence of the X-ray beam (~ 5 sec exposure) inspection at mirror pinhole in front of spectrometer by movable Pellicle beamsplitter 1 4 3 2 W. Morgenroth, Uni Frankfurt

9 W. Morgenroth, Uni Frankfurt
Laser heating table Observation path: New: Andor shamrock spectrometer and iStar iCCD (fast, no filters necessary) two-sided temperature measurement by spectral radiometry (up- and downstream in parallel using double pinhole) 45 watt quartz-halogen tungsten coiled filament lamp (Gooch & Housego), standard of correlated color temperature X-rays W. Morgenroth, Uni Frankfurt

10 Off-axis laser heating setup
Laser path: one 100 W NIR fiber laser nm split into upstream and downstream path polarizing beam splitter cubes and λ/2 waveplates in rotators to control the power movement of lasers in-dependent of (re)alignment of observation path 1 2 3 4 5 W. Morgenroth, Uni Frankfurt

11 Off-axis laser heating setup
Laser path: change of laser focus possible not necessarily an optical element in path of X-rays but: basic alignment might be more difficult due to reflection in diamond planning: exchange the stepper motor system by Newport MFA linear stages with sub micron resolution Temperature range: K – 4000 K W. Morgenroth, Uni Frankfurt

12 Temperature determination
collection of up- and downstream spectra in parallel exposure time in the second to sub-second range analysis by BGI program at once wavelength range usable: 550 to 850 nm example: Pt foil in symmetric DAC, up- and downstream W. Morgenroth, Uni Frankfurt

15 W. Morgenroth, Uni Frankfurt
On-axis laser heating 1 200 W IPG fiber laser, 1064 nm experiments reaching for ultimate high pressure but: glassy carbon mirrors for laser beam transport in X-ray beam path but: no independent change of laser focus therefore: this path will include piShapers 2 X-rays W. Morgenroth, Uni Frankfurt
