| This gas-loading system is designed to load gases at high pressure into diamond anvil cells. The system has the ability to load many kinds of diamond anvil cells with a closure mechanism using motor driven screws which close a clamping device, not the cell itself. This design makes it easy to pressurize new cell designs by using a different clamp or different spacer. The gases can be loaded at pressures up to 29000 PSI, The gases to be loaded will be primarily Helium, Neon, and Hydrogen. The system has optical access for sample viewing and online ruby fluorescence pressure measurement. A vacuum pump is used to clean the system before loading. |

Absorbed pump light at 532 nm excites the Cr ion into excited states. The lifetime of these levels is short 3+ (50 ns), so that the excited ion quickly relaxes by making a transition to the long-lived metastable state. The energy which is lost in this process is nonradiative and goes into heating the crystal by generating phonons or vibrational excitations of the crystal atoms. The metastable energy level must have a lifetime which is long enough to enable the Cr ions to remain excited until a photon having the precise energy comes along to de-excite it.The lasing line in ruby is the so-called "R1-line" having a wavelength of 694.3 nm. The fluorescence lifetime of the R1-line is several ms. |

| A primary advantage to the lift-out technique over other specimen preparation methods is that specimens may be prepared from the starting bulk sample with little or no initial specimen preparation. The lift-out method also has significant implications in the overall analytical approach to a site-specific problem. Besides, the lift-out technique is very useful for TEM sample preparation and often used to lift out the sample and in-situ combination. | |
