| 41. | The horizontal coordinates can be reconstructed from the hit pattern in the photomultiplier array ( s ).
|
| 42. | Photomultiplier tubes, light guides, and silicon photomultipliers are examples of instruments used to collect this light.
|
| 43. | It consists of 50, 000 tons of pure water surrounded by about 11, 200 photomultiplier tubes.
|
| 44. | This statement in the first paragraph of the photomultiplier tube article struck me as possibly outdated and unsubstantiated:
|
| 45. | Inside are four photomultiplier tubes ( 3-8 " and 1-10 " high QE ).
|
| 46. | High-energy particles striking the water result in Cherenkov light that is detected by the photomultiplier tubes.
|
| 47. | A large number of photomultiplier models are available having various combinations of these, and other, design variables.
|
| 48. | An additional photomultiplier system viewed a beam splitter in the optical path and was used as a star mapper.
|
| 49. | The fibers ends are optically coupled to a pair of photomultiplier tubes ( PMTs ) to detect photon bursts.
|
| 50. | This is contained in a spherical acrylic tank surrounded by 255 photomultiplier tubes and many layers of radiation shielding.
