Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Future development and applications of accelerators and electron devices in the fields of free electron lasers (FELs), high-frequency vacuum electronics, high-power microwave devices, and electron beam lithography are partially restricted due to the electron source brightness. A high brightness electron gun with small emittance and high average beam current is one of the key goals in current technological developments. RF electron guns have the ability to reduce emittance growth due to the space-charge effects. Among RF guns, thermionic guns are quite attractive because of their simple configuration with no high voltage stage or complicated laser systems. In addition, the high acceleration reached in the gun cavity (up to 100 MV/m) can easily compress the bunch lengths to have sufficient peak current for FEL driving. On the other hand, Back Bombardment (BB) effect limits the wide usage of Thermionic RF guns worldwide. In this book, BB phenomena, associated effects and method of mitigations are presented. Numerical Model for simulating the effect of back bombardment in thermionic RF gun is used to discus the phenomenon. 104 pp. Englisch.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The aim of this work is to apply a recently developed technique to separate a composite TL glow curve into its individual components of glow peaks. In addition, this work aims to evaluate the trap parameters of each peak in sequence by using a program based on first- or general-order kinetics. In this work, two newly curve-fitting programs have been suggested to simulate the glow curve and to obtain the trap parameters of the glow peaks. The first program was designed to obtain b and no by using non-linear curve fitting program based on the general-order equation. This program was executed with the aid of a recent adaptation of Hoogenstraaten s method for obtaining E and S' in the case of general-order glow peaks. The second curve-fitting program was designed to obtain the trapping parameters b, E, S' and no of the first-, second- or general-order glow peaks. Finally, this work aimed to introduce theoretical studies on the physical and environmental factors, which affect the thermal fading of TL signal.…
