    A forced flow of liquid nitrogen and supercritical helium has been chosen for the cooling of the cryoshields and cryocondensation panels for this cryopump. The reasons for this selection are to minimize the inventory of cryogens (to minimize nuclear heating) good heat transfer conditions and minimum time for transient conditions such as cool-down, regeneration and warm-up.

  • Liquid Helium » Environmental Health Safety »

    Liquid helium is inert, colorless, odorless, non-corrosive, extremely cold, and nonflammable. Helium will not react with other elements or compounds under ordinary conditions. Since helium is non-corrosive, special materials of construction are not required. However, materials must be suitable for use at the extremely low temperatures of liquid helium.

    Liquid helium is a physical state of helium, at very low temperatures if it is at standard atmospheric pressures. Liquid helium may show superfluidity.. At standard pressure, the chemical element helium exists in a liquid form only at the extremely low temperature of −269 °C (about 4 K or −452.2 °F). Its boiling point and critical point depend on which isotope of helium is present: the ...

  • New Cooling Technology Offers Helium

    Because the helium gas remains cold and does not condense into a liquid, the system avoids the possibility of quenching. While relatively rare in MRI machines, quenching—in which a malfunction causes the helium to convert back to gas and escape the cryogenic chamber, effectively demagnetizing the MRI magnet—can be both damaging to the machine and dangerous to anyone near the machine.
