function of 1.55 eV for cesium but later
work with ERMA and negative electron affinity ( NEA ) photocathodes (to be discussed later)
indicates that the lower value is correct.
Synchroscan And Single-Shot Operation Of Photochron IV Streak Cameras
One of the possibilities for extending the near infrared photosensitivity thresholds of
electron-optical streak and framing cameras to wavelengths >l.5ym involves the exploitation
of negative electron affinity ( NEA ) photocathodes 1 °.
For a low energy IPES, a much lower electron beam current of a few to tens lA
was used from a BaO cathode or a negative electron affinity ( NEA ) photocathode for spin-polarized IPES as explained later in Sect.11.5.
Synthesis Of The Multialkali Photocathodes By Molecular Beam Epitaxy
of the evident success in fabrication of the negative electron affinity ( NEA ) photocathodes , the classical type photocathodes, namely the silver -oxygen- caesium (S1) and
multialkali antimonide (511, 520, 525, etc.) photoemitters still attract attention of the
experimentalists due to their very high …
Efficient Linear Upconversion Of Infrared To Visible In Impurity-Doped GaP
It may also be possible to take advantage of this method to use the negative electron affinity ( NEA ) photocathode for the detection of middle and far infrared radiation.
High photon counting efficiency in the near-IR (0.6 um--0.9 um) with a GaAs Ranicon
We present results of an evaluation of the first RANICON detector with a Negative Electron Affinity ( NEA ) photocathode , known as the Red-RANICON.
A study of the NEA photocathode activation technique on a [GaAs(Zn):Cs]: O-Cs model
So we present a new negative electron affinity ( NEA ) photocathode photoelectric emission model: [GaAs (Zn): Cs]: O - Cs.
Comparative study of GaN and GaAs photocathodes
Taking GaAs and GaN as representation, Negative electron affinity ( NEA ) photocathode has many virtues,
such as high quantum efficiency, low dark current, concentrated electrons energy distribution and angle distribution,
adjustive long-wave threshold, great potential to extend the long-wave spectral response …
Direct deposition of GaN-based photocathodes on microchannel plates
Negative electron affinity ( NEA ) photocathodes were
fabricated by cesium activation of the p-type GaN films in vacuum.
Evaluation system of negative electron affinity photocathode
