The X-ray diffraction facility @ICSN is equipped by two ® RIGAKU generators:
A Microfocus high-intensity sealed tube X-ray source MicroMax-003 (30W power consumption)
(λKαMo= 0.7103 Å ;Ø beam = 120 μm)
This XtaLAB diffractometer which is dedicated to chemicals small crystals, strongly diffracting beyond atomic resolution limit, is equipped by:
- A double-bounce confocal optic MaxFlux®
- A kappa geometry goniometer
- A Dectris® Pilatus3R-200K-A direct photon counting detector
- An Oxford® 800 Series Cryostream with auto-refill system (temperature range at the sample 90-400K
Average time for collection of complete dataset 2-3hours, structural connectivity elucidated within one hour.
A Microfocus rotating anode MM007 HF (1.2 kW maximum power)
(λKαCu= 1.5417 Å ; Ø beam = 200 μm)
Two available beamlines are dedicated to the analyses of small organic and biological samples and are appropriate to detect anomalous dispersion from light atoms N, O, F …, S, Cl useful for absolute configuration determination and protein phasing.
Beamline 1 :
- Osmic CMF optic
- Fixed Chi, 3-axis goniometer
- A RAPID™ II curved large-area detector (2θ range of 204°)
- An Oxford® 600 Series Cryostream (Temp. range : 90 – 375 K )
- dmin 0.8 Å
Beamline 2 : (work in progress)
- VarimaxHF optic
- Phi-2θ goniometer
- RAXIS IV ++ IP detector
- A Rigaku Xtream 2000 Cryostream (Temp. range : 93 – 277 K )
- dmin 1.2 Å
Data collection usually last several hours (o/n) and more if necessary.

- A SZX16 Stereo Microscope
Dark field and polarization capabilities and large zoom ratio of 16.4 :1 for 11.2x – 184x magnification with 10x eye-objective and 1.6x objective enable us to image and mount crystals.
