| 21. | A photomultiplier tube is placed on the top of the aluminum casing covering each scintillator.
|
| 22. | This photon is multiplied in a photomultiplier tube which converts light into an electrical signal.
|
| 23. | He pioneered the use of photomultiplier tubes to measure the infrared radiation of cold stars.
|
| 24. | In time resolved fluorometry the fast photomultiplier tube is the only practical single photon detector.
|
| 25. | The target is to be instrumented by 60 to 100 eight-inch photomultiplier tubes.
|
| 26. | Surrounding the tank are 13, 000 photomultiplier tubes that detect the faintest flash of light.
|
| 27. | The scanner had a single photomultiplier detector, and operated on the Translate / Rotate principle.
|
| 28. | Elements of photomultiplier technology, when integrated differently, are the basis of night vision devices.
|
| 29. | However, owing to the avalanche of current, a reset of the photomultiplier is required.
|
| 30. | This fluorescent light is typically recorded with a photomultiplier tube ( PMT ) or filtered photodiodes.
