Gas Loading system (Operational)

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.

Gas-loading system

Pressure transducers: There are two pressure transducers in the system to measure the pressure in the low pressure system and the high pressure system. The transducers produce a 0-5V output over their full scale pressure range. The low pressure transducer Honeywell model AP141DM, 2C10A has a full scale pressure range of 2500 PSI. The high-pressure transducer Honeywell model AP141EN, 2C10A has a full scale pressure range of 30,000 PSI.
