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...
High Power Factor and High Efficiency— You Can Have Both
Although improving the power-supply power factor (PF) can offer significant and necessary reductions in distribution losses, it is usually assumed that adding an active power-factor correction (PFC) stage will reduce the supply’s internal efficiency. It doesn’t have to be this way. This topic shows that several new system architectures are possible that can minimize system losses, accommodate a...
متن کاملI said, you said: the production effect gets personal.
Saying a word out loud makes it more memorable than simply reading it silently. This robust finding has been labeled the production effect and has been attributed to the enhanced distinctiveness of produced relative to unproduced items (MacLeod et al. Journal of Experimental Psychology: Learning, Memory, and Cognition, 36, 671-685, 2010). Produced items have the additional information that they...
متن کاملSpatial trigger waves: positive feedback gets you a long way
Trigger waves are a recurring biological phenomenon involved in transmitting information quickly and reliably over large distances. Well-characterized examples include action potentials propagating along the axon of a neuron, calcium waves in various tissues, and mitotic waves in Xenopus eggs. Here we use the FitzHugh-Nagumo model, a simple model inspired by the action potential that is widely ...
متن کاملfMRI Gets BOLDer at High Fields
The majority of fMRI experiments are conducted based on the blood oxygenation level dependent (BOLD) contrast [1-3], which is derived from the fact that deoxyhemoglobin is paramagnetic while oxyhemoglobin, similar to tissue, is diamagnetic, and changes in the local concentration of deoxyhemoglobin in the brain lead to alterations in the MRI image intensity. It is generally accepted that neurona...
