Special-purpose data not represented by fixed promoted fields are preserved in TUBE_SECTION_PARAMETER. Klystron maximum beam voltage/current, collector dissipation, RF drive/output, cooling, and frequency data are preserved as parameters; no semantically matching standard plate/screen promoted fields were forced.

Source-dependent data

Operating conditions by source

Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.
