Broad band p-Ge optical amplifier of terahertz radiation
A solid state broad band amplifier of terahertz radiation ~1.5–4 THz!, based on intersubband transitions of hot holes in p-Ge is demonstrated. The gain is investigated as a function of applied magnetic and electric fields by transmission measurements using a laser system with two p-Ge active crystals, when one operates as an oscillator and one as an amplifier. A peak gain higher than usually re...

در محیط های دانشگاهی ایران ، آموزش ترجمه واژگان هم آیند که به منزله امری لاینفک برای دانش جویان رشته مترجمی زبان می باشد، تا حدود زیادی نادیده گرفته شده است . این واقعیت باعث شده است تا دانش جویان رشته مترجمی زبان در ترجمه ی واژگان هم آیند اشتباهات بسیاری مرتکب شوند. این پژوهش توجه ویژه ای به ترجمه واژگان هم آیند داشته است. برای مشخص نمودن مشکلات و استراتژی های مورد استفاده ی دانش جویان در ترجم...
15 صفحه اولThe Free Electron Laser Klystron Amplifier Concept
The simplest high gain free electron laser (FEL) amplifier concept is proposed. A klystron amplifier has the useful property that the various electronic processes take place in separate portions of the amplifier, rather than overlapping as in FEL amplifier with an uniform undulator. The klystron consists of two fundamental parts: succession of 2-3 cascades (modulator), and an output undulator (...
متن کاملThe X-band Klystron Program at Slac*
The X-band rf source development at SLAC can be considered a qualified success. A total of twelve klystrons were built. Six of them are still in use. The latest tube, XL4, produced 75 MW at an efficiency of 47.5 percent. However, victory cannot be declared as yet, since an NLC prototype has not been fully designed and the decision between permanent magnet focusing and a super-conducting solenoi...
متن کاملX-band Klystron Development at Slac
The development of X-band klystrons at SLAC originated with the idea of building an X-band Linear Collider in the late 1980’s. Since then much effort has been expended in developing a reliable X-band Power source capable of delivering >50 MW RF power in pulse widths >1.5 μs. I will report on some of the technical issues and design strategies which have led to the current SLAC klystron designs.
