understand protein behavior in solution. The probe used in SAS techniques can be an X-ray Beam (SAXS) or a Neutron beam (SANS). SAXS is very powerful for soluble protein but cannot distinguish between molecules ... detergent, while SANS can: using specific deuteration, the detergent can be made invisible to the neutron beam. In consequence, SANS is ...

The emitted scintillation ... ion light is reflected to the detector, which is orientated perpendicular to the incident neutron beam. Two heating cartridges inserted ...

primary white beam is reflected by a focussing monochromator made of 9 highly oriented pyrolytic graphite (HOPG) providing an important flux at the sample. The monochromator housing has two beam holes at take-off ... 85° and 115°, corresponding to 4.5 Å and 5.6 Å beams with HOPG and incorporates the slit systems and cooled Beryllium filter in a way ...
