the Cherenkov radiation is detected, usually by photomultiplier tubes (PMTs), and the cone of emission reconstructed. The axis of the cone gives the direction of the particle, and the light yield ...

releasing faster-than-light particles and so causing a faint blue flash — the eerie Cherenkov radiation seen in nuclear reactor pools. However, detecting the flash and converting it into a ...
