Progress Reports on the ETF Rebuilding Project

Just curious, would it be possible to get an adequate clean vacuum without bakeing the tube? I know it sound like a strange idea, but is it even remotely possible using modern equipment?

It's a question of process time and the dislodging of adsorbed contaminants, not the modernity of the equipment. A vacuum pump cannot draw contaminants in the tube from a distance, it can only trap them when they travel randomly to the pump.
