ANNIE uses early prototypes of Large Area Picosecond Photodetectors (LAPPDs) to achieve high precision timing.
Notes on verification
Confirmed by multiple independent primary sources including ANNIE's own Letter of Intent, Expression of Interest, official Fermilab project page, and a conference proceeding on reconstruction techniques. [tier=silver indep_score=1.0 clusters=2 claim_tier=notable]
