42.3: An Electron Gun with Gun Pitch Modulation
SID Symposium Digest of Technical Papers, 2001Abstract Philips Cybertubes use virtual Gun Pitch Modulation (GPM) in the Deflection Unit. Realizing GPM in the gun itself can make the system more compact and more cost effective. The beam deviation is achieved either by electric field variations induced by a dynamic voltage inside the gun or by a magnetic field induced outside the ...

Electronic gun (Taser®) injuries
Annals of Emergency Medicine, 1987The Taser is an electrical weapon used for immobilization. Two hundred eighteen patients who were shot by police with a Taser for violent or criminal behavior were compared to 22 similar patients shot by police with .38 Specials. The long-term morbidity rate was significantly different for "tasered" victims (0%) and for those with bullet wounds (50 ...

Electronics and The Gun Environment
Ferroelectrics, 2006Current advances in gun launched projectiles demand the incorporation of on board electronics. These on board electronics consist of both conventional ceramic and plastic encapsulated components as well as Micro-Electronic-Mechanical-Systems (MEMS). The materials used in all of these devices are usually brittle in nature and contain coatings that are ...

Abstract : The first gun developed was the plasma cathode electron gun. The electron source in this device is a plasma generated within a low-voltage, hollow-cathode discharge; a thermionic emitter is not required. Electrons extracted from the plasma pass through a triode-type control grid structure and are accelerated to high energies in a plasma-free

1959 International Electron Devices Meeting, 1959
A high-demagnification electron gun with a small spot size was developed by deflecting the electron beam before it enters a large focusing lens. The pre-focusing deflection allows close spacing between the focusing lens and the tube screen. The diameter of the focusing lens is large compared with the beam deflection to keep spot distortion at a minimum.

Proceedings of the IRE, 1934
The function of the electron gun irrespective of the purpose for which the cathode ray tube is used is to generate, to concentrate, to control, and to focus an electron beam to a spot of a desired size. This paper describes the theory of the above-mentioned functions.

Cosmic Research, 2013
Studies of three versions of electron guns (0.3 kV, 0.14 A; 20 kV, 0.1 A; 40 kV, 0.05 A) intended to operate aboard spacecraft during various space experiments are presented. The computer simulation results of electron-optical systems are given, the optimization of cathode-heating units and heat removal system are performed, circuit design of the gun ...
