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-pressure water injection injury
Patients that present with high-pressure injection injuries most often have hand or digital involvement. Overall, highpressure injection injuries to the hand are uncommon and tend to be occupation related. The usual cause is industrial equipment, with machinery such as grease guns, spray guns and diesel engine injectors accounting for most of these injuries. Materials injected include the follo...
متن کاملWater Works in India
Most mornings, the line begins to form at dawn: scores of silent women with babies strapped to their backs, buckets balanced on their heads, and in each hand a bright-blue plastic jug. On good days, they will wait less than an hour before a water tanker rumbles across the rutted dirt path that passes for a road in Kesum Purbahari, a slum on the southern edge of New Delhi. On bad days, when ther...
متن کاملCoal Disintegration Using High Pressure Water Jet
2 Research method Different methods of coal processing into fuel [1, 6, 12] usually require its intensive comminution. Such situation needs the creation of new technologies for coal micronization [4, 11, 17] that enlarge specific surface of coal micro particles what finally intensifies burning process of such coal dust. Some interesting effects of water-coal mixture ensure waterjetting technolo...
متن کاملHigh pressure nucleation in water/nitrogen systems
Nucleation rate measurements of water in the presence of nitrogen as a carrier gas are reported at total pressures near 10, 25, and 40 bar, and temperatures of 230 and 250 K. The results were obtained using our pulse-expansion wave tube, particularly suited for high pressure nucleation research. Enhanced fugacity of water vapor in the mixture, due to the presence of nitrogen, was quantitatively...
