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...
Modeling of microdischarge devices: Pyramidal structures
Microdischarge ~MD! devices are plasma sources typically operating at 100s Torr to atmospheric pressure with dimensions of 10s–100s mm. Their design in based on pd (pressure3characteristic dimension! scaling; smaller dimensions are enabled by higher operating pressures with typical devices operating with pd51 – 10 Torr cm. MD devices have exhibited behavior that resemble both Townsend and hollo...
متن کاملSymmetrical Pyramidal Horn Antennas Based on Ebg Structures
This paper presents a novel pyramidal (EH) horn antenna based on Electromagnetic Band Gap structures (EBGs). The reported pyramidal woodpile-based horn antenna possesses a symmetrical radiation pattern and a wide operating frequency range. Such antennas can substitute metallic horns in certain circumstances, which is especially valuable for millimetre and THz devices. The principle of creating ...
متن کاملSegmentation of 3D range images using pyramidal data structures
Given a 3-D range image of a scene containing multiple arbitrarily shaped objects, we segment the scene into homogeneous surface patches. A new modular framework for the segment& tion task is proposed. In the first module, over-segmentation is achieved wing zeroth and first order local surface properties. The segmentation is then relined in the second module using high order surface representat...
متن کاملClassical versus quantum structures: the case of pyramidal molecules
In a previous paper we proposed a model to describe a gas of pyramidal molecules interacting via dipole-dipole interactions. The interaction modifies the tunneling properties between the classical equilibrium configurations of the single molecule and, for sufficiently high pressure, the molecules become localized in these classical configurations. The model explains quantitatively the shift to ...
