Activity Description:
|
Photons are created in scintillator devices in most modern particle detectors. These photons yield information about particle collisions that must be measured and decoded. This Website follows the track of a photon as it enters a photomultiplier tube (pmt), an amplifying device that increases the effect of a single photon to levels that are measurable. This signal amplification is crucial; without it, no information exists for decoding.
The site presents information regarding the innards of a pmt and allows students to investigate predictive mathematical models describing the signal increase under different, adjustable parameters. |
