Here are the dimension of the Nb crucibles I use (I guess they are exactly
the same as the Ta ones...):
Total lengh of the crucible from the base of the CF35 flange: 205.5 mm,
included a welded bottom of 5.1 mm in thickness (drilled in its center with
a hole of ca 2.5 mm in depth).
OD: 15.70 mm
ID: 14.41 mm
The crucible is welded on a classical CF35 flange
Sorry for the mm... rather than inches...
