Chem process chamber with microwave heating.
(OP)
I have a proof of concept i am working on and i was hoping someone could give me some pointers on the three main problems i am having
1:I need a window that the microwaves can pass through and still hold a vacuum. will glass work? Plastic? how much loss/heat to get rid of off the glass plate. If nominal it will be fine.
2:I need to be able to change the output very precisely because i need to be able to count the BTU's in and out of the chamber. Can i use pulse width modulation? Does the magnetron turn on off that fast? If i lower the input voltage it will just shut off rite?
3:I am hoping to drop the energy directly into the crucible if there is a metal plate in it it will absorb the microwaves and i will not need to "tune" the chamber rite?
Well thanks if anyone can help note that i will have a metal shield around the output of the magnetron and have no holes in chamber (other than window for said microwaves to go in) and have no intention of microwaving myself.

Why not use induction heating? About a hundred times less complicated.

If you look at microwave glass window patents, you will find some that can withstand hundreds of psi (I think they use them in submarines).
