Customized variable temperature low-temperature platform 4K liquid helium thermostat

CCS（Closed Cycle System）The refrigeration machine has been utilizedG-MThe thermodynamic cycle principle compresses and expands helium gas. The compressor provides the high-pressure helium gas required during the cycle, which is transmitted to the cold head through a flexible metal helium gas pipeline. The compressed helium gas expands and cools inside the cold head, and the expanded low-pressure helium gas returns to the compressor for repeated cycles. The refrigeration unit consists of two stages of cooling stages. The first stage is used to cool the anti thermal radiation screen around the sample, while the second stage is used to cool the sample.Customized variable temperature low-temperature platform 4K liquid helium thermostat
