No, do read at page 27 first. There is some handling in a glove-box 
filled with argon and movement from that one before final assembly etc.

Doable, but not quite the same thing as you described. There is patents 
for CBT solutions where the ampule is broken when placed in the CBT, 
complete with metal cages to handle the ballistics of glass splinters.

Doing it once is one thing. Doing it several times is another. A 
home-made tube is bound to have an experimental touch to it. So the 
caesium oven needs to be isolated when experimenter tinkers around.

In comparison a rubidium setup seems much safer as it is sealed up in 
its glass-ware for the rest of the device life unless you are very clumsy.
