Summary on Grant Application Form |
|
There is an urgent need to enhance the HRPD 90 degree bank to match its count-rate with that in backscattering. Although this bank offers a resolution five times better than that on POLARIS and a factor three better than that proposed for GEM, with matching benefits across the whole User Programme, there is a quantifiable problem with parameter precision from the existing bank. This routinely compromises a significant number of experiments, particularly those in complex sample environments. We therefore propose to enhance the available detector area on HRPD by constructing banks at +/- 90 degrees which will offer a factor of 10 increase in countrate over that currently available and allow count-rate matching with backscattering. This will have significant impact and provide new opportunities particularly in the areas of high-pressure diffraction (especially at pressures up to 0.6 GPa accessed by gas cells), exotic environments including in-situ diffraction and catalysis studies, zeolite structures, larger unit cell materials and mineralogy. The routine use of multi-histrogram methods will enhance both the quality of science and speed of results across the complete User Programme.
