Monitoring the helium level of an MRI scanner

WebWhen super-cold helium leaks into the MRI room, it can affect the temperature and pressure in the room, and displace oxygen — causing hospital staff and patients trapped inside to suffocate. Lab workers are unable to see or smell the liquid helium, so there isn’t a way for them to spot a leak and evacuate. Web10 jan. 2024 · In the diagram, we can see that at temperatures below 20K (-253C) all these gases will condense to pressures below 10 -10 mbar, which means pure ultra-high vacuum! Such temperatures can be easily maintained with commercial cryocoolers (these are operated by helium gas supplied in a closed cycle remote compressor). immersed translate https://ecolindo.net
