Regarding the emergency gas exhaust, important considerations include, but are not limited
to, the following:
• Amount of liquid helium: Taking the 700/89 Ascend magnet as an example, the total
amount of liquid helium is 218 liters. In case of a quench, the liquid transforms into gas
and expands by a factor of 740. Therefore, the total amount of helium evaporated gas in
case of a quench will be ca. 76.3 m
3
(2,695 ft
3
).
• Maximum helium gas flow: The maximum flow of helium gas is calculated on the as-
sumption that half of the volume of liquid evaporates in 1 minute, thus the maximum flow
would be 175 m
3
(6,180 ft
3
) for the 750 WB US
2
magnet. The gas should be removed
from the room immediately through an emergency exhaust system.
