Dedicated or Add-On

The heart of the TR-USAXS is the motorized multi-bounce monochromator and analyzer crystals.
These can offered either in
- Dedicated standalone USAXS system
- Extended USAXS system with SAXS capabilities
- Add-on to existing GANESHA systems
Here’s a litle guiance on what we can offer:
Dedicated USAXS
For users with an existing SAXS instrument, who want a stand-alone USAXS to compliment and extend the data range to low q, we offer a compact solution with the following:
- Sealed tube line source with collimating optic
- Stationary Monochromator, Sample and Analyzer all contained in a single vacuum chamber
- NaI detector for collection. A filter box is incorporated at the incident beam before the monochromator to cut down the intensity, so that the detector doesn’t saturate
Extended USAXS
For users looking for a versatile USAXS that can extend the range to conventional SAXS, we offer a hybrid system with
- Bonse-Hart crytals that automatically move out of the beam
- Slit apertures closing in to define the beam in a line focus or point focus to continue SAXS collection
- imaging the scattering continuously at all angles on a linear or area detector
Ganesha Add-on
And finally for those fortunate to already own a Ganesha SAXS, the TR-USAXS Monochromator and Analyzer can be mounted inside the vacuum chamber, so that the existing source and Pilatus detector can be used. The advantages are:
- The sample can be investigated by USAXS and SAXS under the same conditions
- Economy of purchase, since no additional source or detector are required.
- Lowest noise. The Pilatus area detector behaves as a virtual slit, with background orders of magnitude lower than a NaI detector
