Cylindrical gas pressure cells and gas intensifiers
Various cylindrical gas pressure cells operated in conjunction with the appropriate gas intensifiers are available. They are typically used across a number of diffractometers and spectrometers at the SNS and HFIR. CO2, CH4, He, N2 and Ar are some of the gases commonly used in these cells. Other gases may be utilized, pending technical review. An example of use and development for diffraction at SNS can be found here: Santos et al. RSI 89, 092907 (2018).
For specific experiments, please contact the instrument team of the instrument in question. For general inquiries and possible future opportunities please contact Antonio dos Santos.
