photocathode उदाहरण वाक्य

Photomultipliers with large distances between the photocathode and the first dynode are especially sensitive to magnetic fields.
Some portion of these low-energy photons arrive at the photocathode of an attached photomultiplier tube.
This is much like a CRT television, but instead of color guns the photocathode does the emitting.
Pyroelectric photocathodes can be used to produce a vidicon sensitive over a broad portion of the infrared spectrum.
This device converts the emitted photon energy into electrical energy by a photocathode via a series of other electrodes.

The detector uses a micro-channel plate with the sensor being a CsI photocathode to detect the UV light
However, the ion barrier causes fewer electrons to pass through, diminishing the improvement expected from the Gallium arsenide photocathode.
The nanoparticles are deposited on a glass substrate and overlain by even smaller gold nanoparticles that act as a plasmonic photocathode.
Wide-gap solid-state devices or vacuum devices with high-cutoff photocathodes can be attractive compared to silicon diodes.
An image intensifier includes three functional elements : a photocathode, a micro-channel plate ( MCP ) and a phosphor screen.
