emittance control in high power linacs

چکیده این پایان نامه به بررسی اثر سیم پیچ مغناطیسی و کاوه یِ خوشه گر با بسامد رادیویی بر هاله و بیرونگراییِ باریکه هایِ پیوسته و خوشه ایِ ذرات باردار در شتابدهنده های خطیِ یونی، پروتونی با جریان بالا می پردازد و راه حل هایی برای بهینه نگهداشتن این کمیتها ارایه می دهد. بیرونگرایی یکی از کمیتهای اساسی باریکه هایِ ذرات باردار در شتابدهنده ها است که تاثیر قابل توجهی بر قیمت، هزینه و کاراییِ هر شتابدهند...

Optimization Analysis of Feedforward Power Amplifier

The efficiency optimization of a feedforward low distortion power amplifier is presented. Based on the principle of distortion compensation, the main amplifier output power, that of subamplifier, and amplifier efficiency have been accurately derived. In the present analysis, the coupling coefficient of main signal and distortion paths is selected as the optimization parameter because it may ess...

Optimization-Based Feedforward Path Following for Model Reference Adaptive Control of an Unmanned Helicopter

This paper presents an optimization-based approach to let an unmanned helicopter follow a geometrically defined path. In particular, this approach extends reference model following concepts. Instead of using a model of the vehicle dynamics, the optimization is based on the reference model of the controller. By this means, we can calculate the timewise progress on the path by means of dynamic op...

Feedforward Control in Dynamic Situations

This thesis proposal discusses control of dynamic systems and its relation to time. Although much research has been done concerning control of dynamic systems and decision making, little research exists about the relationship between time and control. Control is defined as the ability to keep a target system/ process in a desired state. In this study, properties of time such as fast, slow, over...
