the amount of knowledge here overwelmd me  a lot.
I want to ask if it is a good idea to put the reference voltage box inside a vacuum box with a Peltier cell
with a pwm controller with temperature sensors inside and outside the external box
in order to control the ambient temperature to 25 degrees.

TiN already had the idea with a Dewar flask :)
