Location and Function

The fridge (or refrigerator) is inserted into the inner space of the target magnet from the top.  It takes LHe from the magnet LHe space thru its "separator" and stores LHe in its bottom-most space called "nose".  The nose space is cooled down to 1 K by the helium evaporation method.  The evaporated helium is pulled by the roots pump thru the gate valve or the gate-valve bypass.

Operations

• The incoming helium to the fridge is controlled by the fridge valves, namely the run valve and the bypass valve.  Operational procedures are explained in this page.
• The outgoing helium from the fridge is controlled by the gate valve and the gate-valve bypass.  Operational procedures are explained in this page.
