[time-nuts] So what’s inside that Cs Beam Tube anyway?

[Peter Reilley]

Just throwing this out: would it be possible recover the cesium by heating
the tube but cooling it near where the reservior is?   This might cause the
cesium to migrate in that direction and some of it end up in the reservior?

Pete.
