We have used 2.8M litres of liquid He since 1972. Losses amount to 11.8% on that period and varied between 5 and 9% over the past 10 years. 10% losses is easy and 5% is feasible but requires a permanent staff checking regularly equipment and usage.

Best wishes,
Eddy

Recycling is good for almost all materials, helium is even more non-renewable than most since if left in the atmosphere it evaporates into space.

I hope to reduce that loss but tracking down where it is being lots in a facility of 500 people is a bit of a problem. We are instrumenting the system a lot to try to find more low hanging fruit.
