Application of the HOTWAXS detector for imaging at higher X-ray energies (10–30 keV)

The high overall throughput wide angle X-ray scattering (HOTWAXS) gas detector system, aimed at X-ray diffraction (XRD) and wide angle X-ray scattering (WAXS) applications has been a successful user facility on stations 2.1 and 9.3 at the Daresbury SRS offering high-speed data acquisition. The facility has been duplicated on station I22 of the Diamond light source. The energy range covered by stations I22 and 9.3 is very similar varying from 6 to 30 keV, well above the energy range conventionally covered by gas detectors. Here, we report studies of the options for successful operation of HOTWAXS at the upper end of this energy range, made possible by this particular design.
