This is contained in a spherical acrylic tank surrounded by 255 photomultiplier tubes and many layers of radiation shielding.
42.
In the light pipe the photons travel outside of the microscope's vacuum chamber to a photomultiplier tube for amplification.
43.
The fibers ends are optically coupled to a pair of photomultiplier tubes ( PMTs ) to detect photon bursts.
44.
The barrel region consisted of 64 Bicron bars with light guides leading to photomultiplier tubes outside the magnetic field region.
45.
The compact imaging system utilizes magnetically shielded position sensitive photomultiplier tubes and a compact 1 Tesla permanent magnet MRI platform.
46.
The photons are immediately detected by two arrays of 61 photomultiplier tubes at the top and bottom of the detector.
47.
To detect these flashes of Cherenkov light, photomultiplier tube cameras are used at the focus of large tracking light collectors.
48.
Photomultiplier tubes or avalanche photodiodes convert the light into separate red, green and blue electrical signals for further electronic processing.
49.
Photomultiplier tubes detect the light and convert it into an electric signal, which is amplified and sent to a computer.
50.
The IceCube Neutrino Observatory uses of the Antarctic ice sheet near the south pole with photomultiplier tubes distributed throughout the volume.
