Workflow

  1. Prepare for Base Pressure

    30 minutes

    Gather required equipment and verify conditions for base pressure.

Base Pressure ProcedureStandard

Standard operating procedure for base pressure.

Safety ProtocolStandard

Follow institutional safety guidelines for vacuum technology.

  • Base Pressure Trend

    Plot base pressure over 24 hours — rising rate of rise indicates a virtual or real leak.

  • Bakeout Benefit

    Chamber bakeout at 150°C reduces desorption-limited base pressure significantly.

  • Contamination

    Never open chamber to atmosphere after turbo pump — backstreaming oil contaminates surfaces.

Safety Notes

  • Hot chamber bakeout surfaces exceed 150°C — allow cool-down before handling.
  • Verify vent valves before opening chamber — sudden air rush can eject debris.
