Secondary electron emission studies
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 secondaryelectron-emission material. Secondary-...
متن کاملStatistics of Transmission Secondary Emission
The statistical distribution of the number of emitted secondary electrons per primary incident on transmission alkali-halide dynodes has been studied. For high primary energies (1 MeV), a model based on the theory of dielectric energy loss and the secondary electron-phonon interaction is proposed to account for statistical distributions. Measurements of distributions from 500 i-thick films of C...
متن کاملDevelopment of MicroMegas for a Digital Hadronic Calorimeter
Future particle physics experiments at the International Linear Collider (ILC) [1] will employ the Particle Flow Algorithm (PFA). In order to achieve an optimal PFA performance, a highly granular hadronic calorimeter with a good shower separation is required. One of the suitable and affordable choice for an active part of the hadronic calorimeter is a thin gaseous detector with embedded digital...
متن کاملSecondary-Electron-Emission Instability in a Plasma
A 200-eV electron beam is incident on an electrode in a laboratory plasma. The emission of secondary electrons produces a region of negative differential resistance in the current-voltage characteristic of the electrode. Spontaneous dynatron oscillations are driven by the negative differential resistance when a resonant circuit is placed in series with the electrode. The instability is driven b...
متن کاملSecondary-electron emission from hydrogen- terminated diamond
Diamond amplifiers demonstrably are an electron source with the potential to support high-brightness, highaverage-current emission into a vacuum. We recently developed a reliable hydrogenation procedure for the diamond amplifier. The systematic study of hydrogenation resulted in the reproducible fabrication of high gain diamond amplifier. Furthermore, we measured the emission probability of dia...
