Etymology

Origin of scintillation

First recorded in 1615–25, scintillation is from the Latin word scintillātiōn- (stem of scintillātiō ). See scintillate, -ion

From Science Daily

With each technological shift, the scintillation of new possibilities meets the tug of obsolescence.

From New York Times

Additionally, organic plastic scintillators suffer from low scintillation yields and low particle radiation tolerances due to their low electron density, which hampers their single-proton detection sensitivity.

From Science Daily

It will be the largest and most sensitive scintillation detector ever built.

From Science Magazine

One novel proposal, called THEIA, combines a water-based detector, like Hyper-K, alongside a “scintillation” detector that is more akin to DUNE—to reap the benefits of both approaches.
