[time-nuts] Cheap Rubidium (heatpipe cooling for)

This is all backwards.

The main reason the typical Rubidium box needs a serious heat sink is that 
there is an active heater inside it heating up the lamp to get it up to 
operating temperature.  That part of the system better be "tolerant" of high 
(enough) temperature.

Maybe things would be a lot better/simpler if the heating/cooling we have 
been discussing were split into two sections.  One for the lamp assembly, and 
a second for the electronics.


Anybody know what the thermal coefficient of the lamp is relative to the 
electronics?
