High Current Multibunch Operation at Da Ne
At present the Frascati Φ-factory DAΦNE is operating in multibunch regime with stored currents in the range of 0.5-1 A in both e+ and erings. A longitudinal bunch-bybunch feedback system has been operating in each DAΦNE main ring since the beginning of the machine commissioning. The transverse bunch-by-bunch feedback system working in the vertical plane has been implemented last year in both ri...
متن کاملDa Φ Ne Operation and Plans for Da Φ Ne 2
The e+ecollider DAΦNE, a 1.02 GeV c.m. Φ-factory, has reached a peak luminosity of about 1.4x10 cm s and a peak integrated luminosity in one day of about 8.6 pb. With the current rates the physics program of the three main experiments DEAR, FINUDA and KLOE will be completed by the end of 2007. In this paper we describe in detail the steps which have led to the luminosity improvement and the opt...
متن کاملDa Ne Setup and Operation with the Crab-waist Collision Scheme
In the second half of 2007 a major upgrade has been implemented on the Frascati DA NE collider in order to test the novel idea of Crab-Waist collisions. New vacuum chambers and permanent quadrupole magnets have been designed, built and installed to realize the new configuration. At the same time the performances of relevant hardware components, such as fast injection kickers and shielded bellow...
متن کاملDevelopment of THGEM-based photon detectors for Cherenkov Imaging Counters
The development of a large size gaseous detector of single photons, able to stably operate at high gain and high rate, and to provide good time resolution and insensitivity to magnetic field would be beneficial to future Cherenkov Imaging Counters. The detector could be based on the use of a multilayer architecture of THGEM electron multipliers coupled to a solid state CsI photocathode. A syste...
متن کاملmanipulation in dubbing and subtitling
پژوهش حاضر در چارچوب مکتب دستکاری قرار گرفت و با استفاده از تقسیم بندی دوکات (2007) از شیوه های دستکاری، به دنبال یافتن پاسخ برای پرسش های زیر بود: 1-رایج ترین شیوه دستکاری در دوبله فیلم ها کدام است؟ 2-رایج ترین شیوه دستکاری در زیرنویس فیلم ها کدام است؟ 3-دستکاری در دوبله فیلم ها رایج تر است یا در زیرنویس آن ها؟ این پژوهش از نوع تحقیقات توصیفی- مقایسه ای و پیکره ای می باشد. پیکره تحقیق شا...
