Proportional Counters as Low Energy Photon Detectors
We have investigated the response of an argon-methane proportional counter to monochromatic X-rays in the range 99-277 eV . The apparent nonlinearities in mean pulse height as a function of photon energy and the detailed shape of the pulse height distribution for each energy can be predicted quite precisely using the extensive atomic data available for argon. Based on this understanding, we pro...
متن کاملthe survey of the virtual higher education in iran and the ways of its development and improvement
این پژوهش با هدف "بررسی وضعیت موجود آموزش عالی مجازی در ایران و راههای توسعه و ارتقای آن " و با روش توصیفی-تحلیلی و پیمایشی صورت پذیرفته است. بررسی اسنادو مدارک موجود در زمینه آموزش مجازی نشان داد تعداد دانشجویان و مقاطع تحصیلی و رشته محل های دوره های الکترونیکی چندان مطلوب نبوده و از نظر کیفی نیز وضعیت شاخص خدمات آموزشی اساتید و وضعیت شبکه اینترنت در محیط آموزش مجازی نامطلوب است.
Development of backgammon-type multiwire proportional counters for the detection of x rays
A multiwire proportional counter !MWPC" based on a backgammon-type design has been developed for the detection of x-ray photons in two dimensions over the energy range of 4–6 keV. The MWPC was designed for operation in an experimental spectroscopy application requiring single photon counting over a wide range of count rates, high photon detection efficiency and resolution, and a highly linear r...
متن کاملFull simulation of the Sudbury Neutrino Observatory proportional counters
The third phase of the Sudbury Neutrino Observatory (SNO) experiment added an array of 3He proportional counters to the detector. The purpose of this neutral-current detection (NCD) array was to observe neutrons resulting from neutral-current solar-neutrino–deuteron interactions. We have developed a detailed simulation of current pulses from NCD array proportional counters, from the primary neu...
متن کاملGas Scintillation Proportional Counters for High-Energy X-ray Astronomy
A focal plane array of high-pressure gas scintillation proportional counters (GSPC) for a balloon-borne hard-x-ray telescope is under development at the Marshall Space Flight Center. These detectors each have an active area of ~ 20 cm, and are filled with a high pressure (10 Pa) xenon-helium mixture. Imaging is via crossed-grid position-sensitive phototubes sensitive in the UV region. The perfo...
