In use, the first stage is used primarily for ancillary cooling of the cryostat with the second stage used primarily for cooling the magnet.
32.
In applications the first stage also operates as a temperature-anchoring platform for e . g . shield cooling of superconducting-magnet cryostats.
33.
At the beginning of Season 3 the crew spends about 4, 000 years in cryostats before arriving at the twin planets of Fire and Water.
34.
The cryostat is cooled to-269�C by liquid helium and provides the high-quality vacuum necessary to prevent the highly charged ions from recombining.
35.
For " Herschel ", the solar array is fixed on the bottom part of the baffle designed to protect the cryostat from the Sun.
36.
This may be a furnace for measurements at elevated temperatures ( temperatures to 2000 �C ), or a cryostat for measurements at temperatures below room temperature.
37.
Nowadays few units using multiple cryogens are made with the trend being towards'cryogen-free'cryostats in which all heat loads are removed by cryocoolers.
38.
After a period of vessel leak-checking, beginning in the summer of 2014, the cryostat was evacuated, and magnet testing was completed in July 2015.
39.
Other parts of the system include a liquid nitrogen storage tank, a refrigerator, and a number of cryostats which manage the transition between cryogenic and ambient temperatures.
40.
The MIC is mounted to the helium chamber inside the cryostat vacuum shell, not only to efficiently keep the instruments cold but to seal out any stray light.
