Time dependence of stuff

Dear Git,

So the emission current is definately not constant. And appears to vary quite a lot with pressure in the chamber.
Yep.

Supervisor: "The emission current will be constant. I don't think such a small change in pressure will affect it."
Supervisor: "There is probably no need to measure the pressure of the chamber"

I can only hope that this message reaches you in time git, for my sanity is beginning to wane.

Yours annoyedly,

Sam
