Appendix · TDR acronyms

Acronyms used in the ATLAS Technical Design Reports, from the construction-era volumes through the Phase-I and Phase-II upgrades. Verified against readable TDR body text rather than transcribed from the glossary appendices, most of which are not publicly retrievable — so treat this as broad but not exhaustive. Terms with a full entry above are defined there.
