      The secondary-electron emission (SEE) coefficient, δ, was measured for thermally grown SiO 2 films on a Si wafer. As the thickness of SiO 2 film becomes greater than 40∼50 nm, the SEE curve changes to the double-humped shape having a low δ value from the typical ‘universal curve’ shown at ordinary SEE measurements. We conclude, from a . Stray electrons were produced in the Ames Laboratory linear accelerator by the ion beam striking the target and various other parts of the accelerator. This experiment was done to determine if the stray electrons from parts of the accelerator other than the target could be reduced by using construction materials other than brass.

    To enhance the efficiency of the Multistage depressed collector (MDC) of traveling wave tube amplifiers (TWTs), TiN film was deposited by arc ion plating. The thickness and roughness of the film were respectively measured by scanning electron microscopy (SEM) and atomic force microscopy (AFM). In order to study the effects of the preparation parameters and the process . Field emission from photo-excited nonequilibrium electron distributions were clearly observed, while no enhanced field emission due to optical electric fields appeared up to values of V/nm.

Certain solids emit electrons from their surfaces when subjected to heat (thermionic emission), electromagnetic radiation (photoemission) and/or an electric field (field emission). Much of electronics, including vacuum tubes, cathode-ray tubes in their various manifestations, and electron microscopes, depend on the emission of electrons from metals and the manipulation.

Measurements made on sputtered thin‐film gold‐metaloxide cermets indicate that the secondary electron emission yield is quite similar to that of the dielectric. For Au–Ta 2 O 5 films, the first crossover potential is ≃ 30 V, and the maximum yield of is achieved at V.

These values are essentially independent of the Au/Ta 2 O 5 ratio. Results are also presented. The transition from laminar to turbulent behavior of the electron sheath in a cross‐field gap is examined for the regime B≳B H, where B is the external magnetic field and B H is the Hull cutoff value.

An analytic expression is presented for the critical emitted current beyond which laminar solutions cease to exist. A one‐dimensional particle code is used to corroborate the analytic. material for which th~ sec6ndary electron ratio was a sensi­ tive function of the particle energy, thus offering a means of measurement of the primary particle energy.

Also, the data might assist theo~ists by supplementing the limited amount of data now available onsecondary electron emission due to positive ion bombardment. Secondary emission takes place when a material is bombarded by electrons, ions or photons. In our case we are only interested in the effect of bombard- ment by electrons.

air), or any non-conducting or weakly conducting. The theory of cold field emission of electrons from metals is discussed in many textbooks and monographs, including the monograph by R. Jenkins and W. Trodden, "Electron and Ion Emission From Solids" (Dover Publications, Inc., New York, N.Y., ), Chapter 4.

Chow et al.

The phenomenon of secondary electron emission from the surface. Secondary-electron-emission processes under electron bombardment play an important role in the performance of a variety of electron devices.

While in some devices, the anode and the grid require materials that suppress the secondary-electron-generation process, the crossed-field amplifier (CFA) is an example where the cathode requires an efficient secondary-electron-emission.
