Complete base pressure guide for vacuum technology practitioners. Step-by-step workflow with 4 stages and 2 specialized tools. Covers prepare for base pressure, set up workspace, execute base pressure procedure.
Gather required equipment and verify conditions for base pressure.
Configure workspace, calibrate instruments, and prepare materials.
Follow the established protocol for base pressure, recording observations.
Process collected data, compare against standards, and document findings.
Standard operating procedure for base pressure.
Plot base pressure over 24 hours — rising rate of rise indicates a virtual or real leak.
Chamber bakeout at 150°C reduces desorption-limited base pressure significantly.
Never open chamber to atmosphere after turbo pump — backstreaming oil contaminates surfaces.
