Hi,Mark:
Thanks a lot!
Here is more information about the situation.
The LN2 outlet has a loose handle and when I was unscrewing the hose, the handle dropped and sucked into the bore immdiately.
The spectrometer is 360MHz one and has a wide bore of 89mm.The handle is about 4-5 inch and was ten inches away from the bottom of the bore.I tried to pull this out first, but I can feel that it was held very tightly.I really don't know if pushing can work.I'm also concerned with if the stick will hit the bore or scratch the surface and cause the magnet to quench.
