I have a new filament to be installed in an ionization chamber. How can I provide it with the required voltage and what are the main components to be combined to get a new ionization chamber?
The question is not clear. What kind of instrument ? Have you all the power supplies for a 70 eV electron ionization source ? Do you need an external power supply ? An ionization source should have several DC supplies, for filament heating, for the filament bias of -70 V (relative to other source elements) to accelerate electrons, and also DC for repeller, electron trap, etc.
