I am new to the Time-Nuts list and to the time standard area in general,
so please excuse my questions if they has been asked and answered before.

I just purchased an Efratom LPRO 101 Rubidium frequency standard.  As I
understand it, I must mount it on a heat sink.

 

Question 1:  The lamp and chamber operate at a temperature around 100
degrees C and we must provide sufficient power to heat the unit.  If we
are heating the unit, why do we need a heat sink?  Doesn’t the heat sink
defeat the heating process?

Question 2:  Assuming that there is a reasonable answer to question1 and
a heat sink is needed, how big a heat sink is required?  Are fins
required?  Is forced air required?  In other words, what do I have to do
to mount the LPRO 101 correctly?

Thank you in advance for your assistance.
