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? -- These are my opinions, not necessarily my employer's.
