Under Pressure

I've decided that high pressure diffraction experiments with diamond anvil cells (DACs) are very fiddly (which is apparently a word only used by the English and Aussies). Tiny diamonds, with tiny faces, holding a thin foil, with a smaller hole and 2 grains of sample in the hole. Fiddly.
We have 4 DACs in use. The are called Bass, Leffe, Stella and Emmett. Bass is named in honour of our beverage for the evening.
