Superconductivity, Cryogenics, and Vacuum Technology for Linear Accelerators*
The conventional, 10 -8 ’ Torr-range, ion-pumped vacuum system of the SLAC 3.2~km linear accelerator is briefly described, along with typical performance data. Since polarized electron sources are of increasing importance to high-energy research, the necessary physical environments for such sources is given, and differential pumping and/or isolation systems capable of maintaining those conditio...
متن کاملthe effects of multiple intelligences (focus on musical, visual, and linguistic) and direct instruction on learning grammar: a case on iranian efl students at elementary level
1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
An introduction to cryogenics
These notes aim to give a somewhat basic introduction to the hows (and occasionally whys) of cryogenics. Cryogenics is not a very well defined term; here I have taken it to mean systems that operate at temperatures of 77 K and below, with the emphasis on systems operating below 4.2 K and above 1 K. The first two temperatures are, of course, the boiling points of nitrogen and helium respectively...

متن کاملthe effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus
از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
