Contents are completely enclosed by diamond to hold the pressure. No way to probe otherwise as far as i know.
- s0rce 6y agoX-rays are also widely used to probe high pressure matter within diamond anvil cells Here is an example at an ESRF beamline https://www.esrf.eu/home/UsersAndScience/Experiments/MEx/ID15B/overview.html https://www.esrf.eu/home/UsersAndScience/Experiments/MEx/ID1...
- smartscience 6y agoDon't forget neutrons! Not as quick to measure, and not so good with very small samples, but well-suited to combinations of extreme environments beyond just pressure, such as temperature, magnetic field, voltage gradient etc. https://www.isis.stfc.ac.uk/Pages/Pearl.aspx https://www.isis.stfc.ac.uk/Pages/Pearl.aspx
