SIMULATION / SA-EQP-VACUUM-PUMPDOWN-001

Vacuum pumpdown envelope
Pumpdown

Replay volume, effective speed, leak-floor, and target-pressure vocabulary for vacuum tools without pump selection or operation guidance.

EXPLORE

Start with the observable.

Use this page when the simulation is the primary artifact. The linked lesson explains the concept; the linked lab keeps the visual replay surface available.

guided exploration
  • Read pumpdown time as a relation among chamber volume, effective speed, target pressure, and floor.
  • Compare loadlock, process chamber, and large-chamber recovery teaching cases.
  • Use the card to ask what qualified pump curve, leak rate, and safety review are missing.

RUN CARD

Conditions before conclusions.

The page replays saved vacuum teaching data. It does not select pumps, operate valves, configure interlocks, or diagnose a tool.

precomputed replay

Primary knobs

  • Teaching cases: loadlock roughing, process chamber, large chamber recovery
  • Outputs: time constant, time to target, leak-floor note, normalized recovery index
  • Review focus: vacuum vocabulary for equipment-facing papers
  • Boundary: no pump selection, leak-check procedure, valve sequence, interlock setting, or tool operation
outputs

Saved outputs

  • pumpdown envelope table
  • positive-time check
  • large-chamber ordering check
  • target-above-floor check

METHODS

How the number was made.

Methods are written for citation discipline: the extraction rule matters as much as the plotted value.

method

Use a first-order exponential pumpdown teaching envelope with explicit volume, effective speed, target, and floor fields.

Keep this method attached when reusing the figure or metric.

method

Compute time to target only for public-safe teaching cases.

Keep this method attached when reusing the figure or metric.

method

Check ordering across chamber scale without exposing actual tool parameters.

Keep this method attached when reusing the figure or metric.

method

Attach vacuum vocabulary sources while excluding operating sequences and safety settings.

Keep this method attached when reusing the figure or metric.

LIMITS

What this page does not claim.

The MVP is useful because the limits are visible. These statements prevent a teaching simulation from being cited as silicon evidence.

non-claim

No pump selection, valve sequence, leak-check method, interlock setting, safety procedure, tool operation, or process recipe is included.

Carry this boundary into any derivative note, paper draft, or slide.

non-claim

No gas chemistry, hazardous exhaust, abatement, cryo behavior, turbo-pump detail, conductance model, or real tool geometry is represented.

Carry this boundary into any derivative note, paper draft, or slide.

non-claim

The envelope is a teaching proxy and cannot diagnose vacuum performance or authorize operation.

Carry this boundary into any derivative note, paper draft, or slide.

non-claim

Real reuse requires OEM documentation, facility/EHS ownership, calibrated gauges, qualified leak checks, and owner signoff.

Carry this boundary into any derivative note, paper draft, or slide.

EVIDENCE

Trace the claim back to artifacts.

The evidence route remains the catalog-level browser; this page is the simulation-level reading card.

evidence note

The dataset preserves three public-safe vacuum teaching cases.

SA-EQP-VACUUM-PUMPDOWN-001

evidence note

Verification checks positive times, target/floor consistency, and chamber-scale ordering.

SA-EQP-VACUUM-PUMPDOWN-001

evidence note

The model card keeps valve, interlock, leak-check, and tool-operation boundaries explicit.
