High power ICRH and NB heating results in TEXTOR

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...

Minority heating by ICRH: a tool for investigating burning plasma physics in FAST

A combined Fokker–Planck numerical analysis of the quasi-linear plasma–ion-cyclotron (IC) wave interaction and collisional relaxation of minority ion tails created by IC absorption was performed in order to determine the characteristic fast-ion parameters that are necessary for addressing some of the main ITER burning plasma physics issues, e.g. fast-ion transport due to collective mode excitat...

The dependence of plasma rotation and heating power on the density limit for MARFE onset hasbeen studied on TEXTOR using different mixtures of auxiliary heating methods (ICRH, co-, andctrNBI). The edge density limit in the plasma heated by NBI is two times larger than thatobserved in the plasma heated by ICRH ( PNBI= PICRH= 1.3 MW). The dependence of the densitylimit with regard...

High resolution multiposition Thomson scattering for the TEXTOR tokamak

In this article, the recently installed high resolution multiposition Thomson scattering ~TS! system of the TEXTOR tokamak is presented. Light from a pulsed ruby laser is scattered by the free electrons of the plasma and transmitted by fiber optics to a polychromator for spectral analysis. The Doppler broadened spectrum of the scattered light is analyzed with a Littrow spectrometer, detected wi...
