Cooling the M CT detector
1.
Press on the front edge of the lid of the dewar, which then opens.

Figure 9 The Dewar Opening with the Funnel Inserted
WARNING
Stand where you can see the inside of the funnel as you pour the
nitrogen in. Pour slowly, so that neither the funnel nor the dewar
overflows. If liquid nitrogen runs down the outside of the dewar, it
can damage the optics of the microscope.
4.
Carefully fill the funnel with liquid nitrogen. Stand back and let the funnel
empty completely.
The liquid nitrogen bubbles rapidly as it drains into the dewar. This initial
quantity of liquid nitrogen vaporizes completely as it cools the dewar.
