Replacing Threaded Copper piece on Sample Siphon
Equipment/Beam Line: 

the copper piece on Sample diphon was leaking helium gas to IVC during sample change process. This iece was replaced with a new piece.

Few tips :

-use Certanium 34C solder with its flux

-clean the inside of the SS tube relly good

-hold the tube as normal vertical operating position for soldering

-don't put too much solder!

-check the flow of helium liquid in and gas out before soldering and after

-mazimize the number of threads that are sticking out of the copper torque piece
