Following a grant from the Carlsberg Foundation, applied for by CMC ass. prof. Martin Bremholm and senior scientist Jacob Overgaard, the APEX-II single-crystal diffractometer is now set to undergo major upgrade. With it, the diffractometer will be using X-ray radiation from Silver (chemical symbol Ag) rather than Cupper or Molybdenum as hitherto. Furthermore, the Ag-source features micro-focusing optics yielding a narrow and intense beam. Both are ideal for high-pressure crystallography which routinely employs Diamond Anvil Cells (DACS) for establishing pressurized environments around the sample crystals. These DACS have narrow entries for the X-rays and therefore require a tiny beam cross-section. The angular width of the exiting window (which is a diamond) is also quite limited. This means that the data quality will benefit greatly from the high energy of Ag-radiation, as higher energy generally diminishes the angular range required for collecting good data sets.
