'''Vacuum Pumping and LN2 filling:'''1. # The day before, connect the vacuum pump using the 500mm long vacuum hose (see Fig. 1) and pump-down overnight. 2. # The next morning, check that the vacuum got down to the 10-6 mbar range.3. # Shortly before mounting the instrument, while still vacuum pumping, start filling the cryostat with LN2.  
4. After the first flask, close the cryostat vacuum valve and stop the pump.
5. Continue filling slowly until full, indicated by LN2 boiling in the outer funnel. When full, using a glove, quickly remove the inner funnel and dump the excess LN2 back in the filling flask.
