Could this be taking place here also? D. G. THEODOROU: The photocathode
sensitivity remains stable as long as current is not drawn from it. We have
investigated this effect with the photocathode illuminated and with no high
voltage applied ...

Astronomical Photometry: A Guide
Whereas an ideal photocathode would release one photoelectron for every
impinging photon (the quantum efficiency would then be 100%), in practice there
are large losses in absorption of the incident photons, hence, existing
photocathodes ...

the 8-25 type of photocathode'1 because of its superior performance in the near
infra-red region of the spectrum. The $25 photocathode is a derivative of the 820
type using the same basic chemical constituents; it difl'ers only in the processing
...

Christensen's Physics of Diagnostic Radiology
The photocathode is a photoemissive metal (commonly a combination of
antimony and cesium compounds). When light from the fluorescent screen strikes
the photocathode, photoelectrons are emitted in numbers proportional to the ...

Principles of Naval Weapon Systems
Usually placed in a vacuum tube with high voltage, a photocathode absorbs the
photon, and the energy absorbed is enough (higher than the electron work
function) to release the electron in the vacuum chamber. The voltage potential
moves it ...

Principles of Fluorescence Spectroscopy
A PMT vacuum tube consists of a photocathode and a series of dynodes which
are the amplification stages (Figure Figure 2.29. Schematic diagram of a
photomultiplier tube and its dyn- ode chain. 2.29). The photocathode is a thin film
of metal ...

Handbook of Optoelectronics (Two-Volume Set)
When photons strike a photocathode, electrons in the valence band absorb
photon energy hv,become excited into the conduction bandand diffuse toward
the photocathode surface. When the diffused electrons have enough energy to ...

Photonics and Lasers: An Introduction
A negative high voltage (usually ~ 1 kV) is applied to the photocathode, and the
proper potential for each dynode is maintained by a chain of equal—value
resistors. The anode is approximately at ground potential, and attracts the large
bunch ...
