Acronyms, Acronyms, Acronyms



Few things can be as intimidating to a new student at the tremendous variety of acronyms in everyday usage in experimental physics. Embarrassment can follow intimidation when you reach the point where you really ought to know some particular acronym, but forgot to ask what it meant when you first started!

Some time ago I served as the representative for Nuclear Physics on DOE's ESSC. Network terminology is probably one of the few domains (the military is another) where there are more acronyms in common usage than in experimental physics. I began keeping a "cheat sheet" just so I could understand (some of)  the discussions. That sheet, now augmented by PHENIX terms, forms the basis of this page.

I know there are many more acronyms out there than I've been able to capture in my first go round. Please send me your suggestions, and I will incorporate them here.


A incomplete and undoubtedly incorrect guide to

BA's (Binary Acronyms)

TLA's (Three Letter Acronyms)

AFLA (Another Four Letter Acronym) and
YAFLA (Yet Another Five Letter Acronym)
