Hi
If you separate the the electronics from the physics package then you will need to think pretty hard about magnetic shielding.
The physical package is what needs to sit inside the my-metal.
It is clear though that if you are going to run an LPRO off of batteries, you want to let it warm up. The energy savings likely outweigh the loss of reliability.
The reliability penalty is real. I have indeed "cooked" rubidiums. In each case it was not the heater circuits or the lamp that failed.
The important thing for the exercise is to stabilize temperature. To
what temperature is a matter of choise.
