| 11. | Photomultipliers with large distances between the photocathode and the first dynode are especially sensitive to magnetic fields.
|
| 12. | Some portion of these low-energy photons arrive at the photocathode of an attached photomultiplier tube.
|
| 13. | This is much like a CRT television, but instead of color guns the photocathode does the emitting.
|
| 14. | Pyroelectric photocathodes can be used to produce a vidicon sensitive over a broad portion of the infrared spectrum.
|
| 15. | This device converts the emitted photon energy into electrical energy by a photocathode via a series of other electrodes.
|
| 16. | The detector uses a micro-channel plate with the sensor being a CsI photocathode to detect the UV light
|
| 17. | However, the ion barrier causes fewer electrons to pass through, diminishing the improvement expected from the Gallium arsenide photocathode.
|
| 18. | The nanoparticles are deposited on a glass substrate and overlain by even smaller gold nanoparticles that act as a plasmonic photocathode.
|
| 19. | Wide-gap solid-state devices or vacuum devices with high-cutoff photocathodes can be attractive compared to silicon diodes.
|
| 20. | An image intensifier includes three functional elements : a photocathode, a micro-channel plate ( MCP ) and a phosphor screen.
