physics that is happening inside the cold
finger, which is a cryogenic that goes to low
temperature. I would like to know when there are two pump connected each other (a mechanical one that goes up to
the pressure of 10^-3 mTorr connected to the diffusion bomb and the
diffusion go to a lower pressure of 10^-6 mTorr, the diffusion bomb connected to the cold finger. They used
thermodynamics to explain the physics
behind this and would like a full explanation.
Thank you very much and plis with example
of the pressure of the mechanic pump and
difusion pump.
The cold finger have a two different pressure, one from the water vapour and the other one from the diffusion bomb
This part is more theoretical and it is not an
exercise
An example is the following image:
