We are planning a site for a new 800MHz magnet and consider to make a hole
(2-3 m deep) in the rock floor of sufficient diameter to accommodate the
magnet. However we would like to be able to have the Helium and Nitrogen
containers at the regular floor level (half way above the magnet) using
special helium transfer lines.
Bruker (Sweden) however tells us that the helium container must be at the
same level as the 800 MHz magnet. Is this correct? We would prefer not to
make a new lift/elevator just for this purpose. Is it possible to use
specially elongated (vertically) helium transfer lines?
Thanks for any advice!
Sincerely
Frode Rise
